1990s以来京津冀地区经济增长快速,然而经济发展在行政辖区间并不均衡,且逐渐导致环京津贫困带的形成.为识别经济发展失衡格局的演化过程,首先引入DMSP/OLS夜间灯光和可比价GDP,构建"单位开发活动GDP"表征区域经济发展状况;然后运用Local Moran's I将区域经济发展格局划分为五种类型:HH富化扩散,HL富化极化,LH贫化塌陷,LL贫化制约和非显著;最后以HH类型的边界作为京津冀地区经济发展失衡界线,采用缓冲区分析探讨经济发展失衡格局的演化过程和行政区划等人为因素对经济发展的制约效应.结果表明:① 整体上,1990s以来京津冀地区经济发展失衡格局不断加剧,京津富化扩散与河北贫化制约的规模与强度同时增长;局部上,受京津市区经济发展的外溢效应,京津郊区及区位优势显著的部分河北地区经济发展较快.② 与传统认知的"环京津贫困带"不同,在两个空间尺度上识别出经济发展断层,一为京津市区与郊区之间,二为京津与河北之间,且前者的区域经济发展失衡整体上较后者更为严峻.③ 1990s以来京津冀地区经济发展的失衡格局,整体上受制于城乡二元体制带来的城乡隔离效应,局部上受京津冀三地的行政制约.要实现京津冀地区经济发展的协同均衡,关键在于弱化城乡隔离,并辅以消除行政制约.

Abstract

The Beijing-Tianjin-Hebei region has been experiencing rapid economic development since 1990. However, development has been imbalanced and has been widening the gaps in economies of Beijing, Tianjin, and Hebei. To identify the imbalanced pattern of economic development and analyze its dynamics in the Beijing-Tianjin-Hebei region during 1992-2012, we first proposed a "GDP per human activity intensity" consisting of DMSP/OLS nighttime light data and the constant price of GDP to map economic development. Second, local Moran's I was applied to classify the economic development pattern into 5 types: HH (high values surrounded by high values), HL (high values surrounded by low values), LH (low values surrounded by high values), LL (low values surrounded by low values), and not significant. Third, the boundary of the HH type was used as the line between rich areas and poor areas, and the dynamics of economic development and its response to administration are analyzed by buffer analysis. The results suggest that the spatial pattern of economic development has been imbalanced during 1992-2012, and the HH type in Beijing-Tianjin and the LL type in Hebei have been increasing in area and intensity. The HL type and the LH type in Hebei and suburban Beijing and Tianjin are growing because of the spillover effect of the development in the urban areas of Beijing and Tianjin. Moreover, having a different view from the previous understanding of "one poverty region around Beijing and Tianjin", we identified wealth gaps on two spatial scales: One is inside Beijing and Tianjin, which is between urban and rural areas, and the other is between Beijing-Tianjin and Hebei. Furthermore, the wealth gap in the former scale is larger than the latter. The imbalanced spatial pattern of economic development is a result of the administrative restrictions among Beijing, Tianjin, and Hebei and the urban-rural dual system. Such a result can be attributed to the difference of administrative management and policy exists not only between cities but also between the urban and rural areas of a particular city. In addition, our analysis shows that the latter scale is the main reason for the imbalanced spatial pattern. Therefore, reducing urban-rural differences and administrative constraint is important in realizing balanced economic development in the Beijing-Tianjin-Hebei region.

2.1 研究区概况

2.2 研究流程

2.2.1 区域开发强度 由于时效性,客观性及可获性等特有优势,遥感数据成为重要数据源,引入DMSP/OLS夜间灯光表征区域开发强度.由于夜间灯光是区域人为活动的具象化表征,其与社会经济等人类活动存在显著的相关关系,故夜间灯光可有效衡量区域经济社会发展(生产总值,城市规模,人口分布,植被覆盖,能源消费,城市化等[17-25]),也可量化区域开发的广度与强度.6个评估时间节点所对应的为F101992,F121995,F152000,F162005,F182010,F182012遥感数据.由于客观条件(灯光饱和效应与卫星观测误差等)对原始数据存在一定的"灰箱式"干扰,需依次修正弱化灯光饱和效应与卫星观测误差.

2.2.2 区域经济发展 "环京津贫困带"不断显化源自京津冀区域经济发展格局的过度失衡.区域经济发展是经济增长与社会进步及生态改善等经济--社会--生态所表征的综合概念,社会进步与生态改善均以经济增长为物质基础,没有经济增长就没有坚实的社会进步与生态改善.虽然量化经济发展的评估指标或评估体系往往因人因地存在显著差异,地区GDP却是区域经济发展评估最为基础,最为核心的,其他各级各类的指标或体系多是区域GDP的直接表征或间接量化.同时,为了避免以单一区域GDP量化区域经济发展容易陷入"唯GDP论",尝试性引入夜间灯光表征的区域开发强度,并以单位开发强度的可比GDP表征区域经济发展,如公式(1)所示.

$y = x i × GD P j ∑ i = 1 n x i y j = x i × ( GD P j / Σn x i )$ (1)

2.2.3 时空演化格局 对1992-2012年京津冀地区经济发展失衡格局进行量化识别,先以1 km $×$ 1 km为评估单元,以Local Moran's I空间聚类将京津冀区域经济失衡格局分为非显著类型与显著类型(即HH富化扩散,HL富化极化,LH贫化塌陷,LL贫化制约)[26].而后,分别提取环京和环津的HH富化扩散类型,将其外延识别为京津冀地区经济发展的失衡界线.经济发展格局类型的HH类型代表区域经济发展水平的高值集聚区,将京津冀地区经济发展失衡界线界定为经济发展高值地区向低值地区转变的突变地带,而HH类型即其数值是显著高于周边邻近地区的,其界线意义与本研究定义的经济发展失衡界线存在较高类似性,可以替代之.最后,依次对北京与天津的HH内部,HH外部但属京津市内,河北省域进行间隔2 km的Buffer分析,量化1990s以来京津冀地区经济发展失衡格局的演化过程.

1992-2012年6个评估时间节点的京津冀地区经济发展失衡格局,如表3与图3所示.1990s以来京津冀地区经济发展失衡格局均主要是非显著类型,经济失衡更多的是城市之间与城乡之间的局部失衡.1992年京津冀地区经济发展的显著类型只有HH富化扩散,这表明区域经济发展呈整体弱化,结构简化的失衡格局."环京津贫困带"是京津市区"财富高原"等城区经济与邻近周边的市郊经济之间的严重失衡,这种城乡之间的经济失衡是产生于区域经济发展整体有限背景下市区享受人为行政区划所带来的有限资源严重倾斜."环京津贫困带"早已存在,或是一种计划经济时代的衍生产物,而京津冀区域经济发展失衡是历史上长期演化的结果,非短期突变.

 Figure Option 图3 1992-2012年京津冀地区经济发展失衡的时空演化格局 Fig. 3 Imbalanced pattern of economic development in Beijing-Tianjin-Hebei region during 1990-2012

1995年格局类型有HH富化扩散与LL贫化制约及LH贫化塌陷.HH富化扩散持续扩展而LL贫化制约不断显化,受惠于人为资源倾斜的市区经济发展不断加快,受困于区位制约与政策限制的市郊经济却面临困境,京津冀地区经济发展失衡格局整体加剧.京津市区的邻近周边也散布零星LH贫化塌陷,是市区与郊区及乡村的城乡交错带.受惠于邻近市区经济外溢的城乡过渡地带多呈外延式扩张,而飞地式与点轴式的经济扩张相对较少.京津冀地区经济发展失衡格局呈局部优化而整体恶化,"环京津贫困带"不断显化.行政区划等人为因素所带来的资源倾斜可能是导致京津冀地区市郊之间及城乡之间的经济失衡重要诱因.

2000年与2005年格局类型有HH富化扩散与LL贫化制约及LH贫化塌陷与HL富化极化.HH富化扩散并无显著扩张而LH贫化塌陷与HL富化极化仅散布市区周边,京津市区经济发展的外溢效应增长较快却基数有限,现仅区位优势显著的京津市区周边享受经济外溢.LL贫化制约在张承一带迅速扩张,自然区位劣势与人为政策制约张承享受京津经济的发展外溢,而碳交易等区际调控缺失进一步导致"环京津贫困带"持续加剧,京津冀区域经济发展失衡整体上仍难以得到有效遏制.

2010年经济发展格局类型,与2005年相同.彼此矛盾的HH富化扩散与LL贫化制约同时扩张,京津冀区域经济发展失衡仍是局部改善却总体严峻,贫的越贫,富的越富.经济洼地从张承一带逐渐蔓延至唐山--秦皇岛西北,自然环境与行政制约等人为因素始终困扰京津周边经济,而经济外溢虽局部有效但整体上仍难以扭转京津冀地区的经济失衡趋势.

2012年经济发展格局类型,也与2010年相同.HH富化扩散继续扩张,京津市区经济外溢不断增强,京津市区与邻近周边局部上显著优化.LL贫化制约外扩得到一定阻滞,"环京津贫困带"整体趋势得到一定弱化.京津冀地区经济发展失衡格局得到一定程度的优化均衡,不过尚难以判定这种格局改善是1990s以来京津冀地区经济发展的偶然过程还是必然结果,是暂时性波动还是长期性趋势.

3.2 经济发展失衡界线

3.3 经济发展失衡格局演化

1990s年以来京津冀地区经济发展失衡格局存在着两大显著的发展断崖,即京津的市区和郊区,京津市域和河北地区,而并非传统认识上的"环京津贫困带"一个经济失衡断层,这意味着城乡二元对京津冀地区经济失衡的隔离效应远甚于行政区划所带来的制约效应.邻近京津的贫困县域只是"环京津贫困带"的外围表征,京津市郊之间的经济失衡远甚于京津市域和河北省域之间.尤为严峻的是,1990s以来京津市区与郊区之间的经济失衡并没有得到有效遏制与广泛关注.

1990s以来京津冀地区HH富化扩散地带的经济发展远高于京津外围周边,这个经济断崖并没有随着高速发展的区域经济而逐渐缩小.经济失衡格局演化蔓延扩至周边 100 km,行政制约诱发的"灯下黑"效应甚至局部外延至200 km左右,1990s以来京津冀地区经济失衡格局演化总体上相对稳定.

1990s以来京津冀地区京津市域与河北省域的经济失衡始终显著,距离京津HH富化扩散的河北地区经济发展远低于相似距离的京津地区."环京津贫困带"并非完全受制于自然环境的客观限制,更多的是城乡隔离与行政制约所带来的资源倾斜.整体而言,1990s以来京津冀地区经济发展失衡格局逐渐严峻,"环京津贫困带"不断显化,局部上是受制于京津冀三地各自为政所带来的行政制约,整体上却是城乡二元结构所诱发的城乡隔离.破解"环京津贫困带",实现京津冀区域协同发展,首要在于消除城乡隔离并辅以弱化行政制约.

4 结论与讨论

(1)1990s以来京津冀地区经济发展失衡格局识别为非显著类型与显著类型(HH富化扩散,HL富化极化,LH贫化塌陷,LL贫化制约).彼此对立的HH富化扩散与LL贫化制约(集中于张家口--承德一带)同步扩张表明京津冀地区经济失衡不断加剧.HL富化极化与LH贫化塌陷都散布于市区周边表明京津两市的市区经济的外溢效应虽整体强度有限却不断加强.

(2)1990s年以来京津冀地区经济发展失衡界线并无显著波动,多是缓慢的蔓延扩张,而2005年之后京津市区周边出现局部的飞地扩张.北京经济发展多向区位优势显著的东部扩展,而受制于自然条件与政策定位的京西却相当缓慢.天津经济发展分别向南北两侧同时扩展,区位较好的津西发展滞后或是受制于三地各自为政的行政制约.

(3)1990s以来京津冀地区经济发展失衡格局存在两大发展断崖,即京津市区和郊区之间,京津市域和河北省域之间,而并非传统认识上的"环京津贫困带"一个断层.京津市区和郊区之间的经济失衡远甚于京津和河北之间,城乡隔离效应整体上远大于行政制约效应."环京津贫困带"所诱发的制约效应周边绵延100 km,甚至200 km.受制于自然条件的京津西北地区经济发展虽相对滞后,1990s以来京津冀区域经济发展失衡却多是城乡隔离效应与行政制约效应.弱化京津冀地区经济发展的失衡格局,破解"环京津贫困带",重点在于消除城乡隔离效应并辅以弱化各自为政的行政制约,关键在于以区域多功能性理念建立公共政策决策机制并健全社会生态补偿机制.

As important mechanisms of regional strategy and policy, prefecture-level regions have played an increasingly significant role in the development of China’s economy. However, little research has grasped the essence of the economic development stage and the spatiotemporal evolution process at the prefecture level; this may lead to biased policies and their ineffective implementations. Based on Chenery’s economic development theory, this paper identifies China’s economic development stages at both national and prefectural levels. Both the Global Moran I index and the Getis-Ord Gi* index are employed to investigate the spatio-temporal evolution of China’s economic development from 1990 to 2010. Major conclusions can be drawn as follows. (1) China’s economic development is generally in the state of agglomeration. It entered the Primary Production Stage in 1990, and the Middle Industrialized Stage in 2010, with a ‘balanced-unbalanced-gradually rebalanced’ pattern in the process. (2) China’s rapid economic growth experienced a spatial shift from the coastal areas to the the inland areas. Most advanced cities in mid-western China can be roughly categorized into regional hub cities and resource-dependent cities. (3) Hot spots in China’s economy moved northward and westward. The interactions between cities and prefectures became weaker in Eastern China, while cities and prefectures in Central and Western China were still at the stage of individual development, with limited effect on the surrounding cities. (4) While the overall growth rate of China’s economy has gradually slowed down during the past two decades, the growth rate of cities and prefectures in Central and Western China was much faster than those in coastal areas. (5) Areas rich in resources, such as Xinjiang and Inner Mongolia, have become the new hot spots of economic growth in recent years. For these regions, however, more attention needs to be paid to their unbalanced industrial structures and the lagging social development against the backdrop of the rapid economic growth, driven predominantly by the exploitation of resources.

Environ., 2008, 112(9): 3668-3679. Mapping human settlements from remotely sensed data at regional and global scales has attracted increasingly attention but remains a challenge. The thresholding technique is a common approach for settlement mapping based on the DMSP-OLS data. However, this approach often omits the areas with small proportional settlements such as towns and villages and overestimates urban extents, resulting in information loss of spatial patterns. This paper explored an integrated approach based on a combined use of multiple remotely sensed data to map settlements in southeastern China. Human settlements for selected sites were mapped from Landsat ETM+ images with a hybrid approach and they were used as reference data. The DMSP-OLS and Terra MODIS NDVI data were combined to develop a settlement index image. This index image was used to map a pixel-based settlement image with expert rules. A regression model was established to estimate fractional settlements at the regional scale, which the DMSP-OLS and MODIS NDVI data were used as independent variables and the settlement data derived from ETM+ images were used as a dependent variable. This research indicated that a combination of DMSP-OLS and NDVI variables provided a better estimation performance than single DMSP-OLS or NDVI variable, and the integrated approach for settlement mapping at the regional scale was promising. Compared to the results from the traditional thresholding technique, the estimated fractional settlement image in this paper greatly improved the spatial patterns of settlement distribution and accuracy of settlement areas. This paper provided a rapid and accurate approach to estimate fractional settlements from coarse spatial resolution images at the regional scale by combining a limited number of medium spatial resolution images. This research is especially valuable for timely updating settlement databases at regional and global scales with limited time, labor, and cost.      [本文引用:1] [18] He Chunyang, Ma Qun, Li Tong, et al.Spatiotemporal dynamics of electric power consumption in Chinese Mainland from 1995 to 2008 modeled using DMSP/OLS stable nighttime lights data. Journal of Geographical Sciences, 2012, 22(1): 125-136. Abstract

Electric power consumption (EPC) is one of the basic indices for evaluating electric power use. Obtaining timely and accurate data on the spatiotemporal dynamics of EPC is crucial for understanding and practical deployment of electric power resources. In this study, an EPC model was developed using stable nighttime lights time-series data from the Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS). The model was used to reconstruct the spatial patterns of EPC in Chinese Mainland at the county level from 1995 to 2008. In addition, the spatiotemporal dynamics of EPC were analyzed, and the following conclusions were drawn. (1) The EPC model reliably represented the spatiotemporal dynamics of EPC in Chinese Mainland with approximately 70% accuracy. (2) The EPC in most regions of Chinese Mainland was at low to moderate levels, with marked temporal and spatial variations; of high-level EPC, 58.26% was concentrated in eastern China. Six urban agglomerations (Beijing-Tianjin-Tangshan region, Shanghai-Nanjing-Hangzhou region, Pearl River Delta, Shandong Peninsula, middle-south of Liaoning Province, and Sichuan Basin) accounted for 10.69% of the total area of Chinese Mainland but consumed 39.23% of the electricity. (3) The EPC of most regions in Chinese Mainland increased from 1995 to 2008, and 64% of the mainland area showed a significant increase in EPC. Moderate increases in EPC were found in 61.62% of eastern China and 80.65% of central China from 1995 to 2008, whereas 75.69% of western China showed no significant increase in EPC. Meanwhile, 77.27%, 89.35%, and 66.72% of the Shanghai-Nanjing-Hangzhou region, Pearl River Delta, and Shandong Peninsula, respectively, showed high-speed increases in EPC. Moderate increases in EPC occurred in 71.12% and 72.13% of the Beijing-Tianjin-Tangshan region and middle-south of Liaoning Province, respectively, while no significant increase occurred in 56.34% of the Sichuan Basin.

Urban areas concentrate people, economic activity, and the built environment. As such, urbanization is simultaneously a demographic, economic, and land-use change phenomenon. Historically, the remote sensing community has used optical remote sensing data to map urban areas and the expansion of urban land-cover for individual cities, with little research focused on regional and global scale patterns of urban change. However, recent research indicates that urbanization at regional scales is growing in importance for economics, policy, land use planning, and conservation. Therefore, there is an urgent need to understand and monitor urbanization dynamics at regional and global scales. Here, we illustrate the use of multi-temporal nighttime light (NTL) data from the U.S Air Force Defense Meteorological Satellites Program/Operational Linescan System (DMSP/OLS) to monitor urban change at regional and global scales. We use independently derived data on population, land use and land cover to test the ability of multi-temporal NTL data to measure regional and global urban growth over time. We apply an iterative unsupervised classification method on multi-temporal NTL data from 1992 to 2008 to map urbanization dynamics in India, China, Japan, and the United States. For two-year intervals between 1992 and 2000, India consistently experienced higher rates of urban growth than China, and both countries exceeded the urban growth rates of the United States and Japan. This is not surprising given that the populations of India and China were growing faster than those of the U.S. and Japan during those periods. For two-year intervals between 2000 and 2008, China experienced higher rates of urban growth than India. Results show that the multi-temporal NTL provides a regional and potentially global measure of the spatial and temporal changes in urbanization dynamics for countries at certain levels of GDP and population-driven growth.      [本文引用:0] [20] Roychowdhury Koel, Jones Simon D, Arrowsmith Colin, et al.A comparison of high and low gain DMSP/OLS satellite images for the study of socio-economic metrics. IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2011, 4(1): 35-42. The Operational Linescan System (OLS) onboard the Defense Meteorological Satellite Program (DMSP) group of satellites, unlike other passive remote sensing sensors, is capable of recording the emissions from artificial lights on the earth surface. Along with detecting light from forest fires, shipping fleets and gas flares, the OLS sensor also records the light emitted from cities at night. This paper reports on a study that uses the DMSP Operational Linescan (DMSP-OLS) images with fixed gain settings of 20 dB and 50 dB to model selected metrics used in the Indian census for the state of Maharashtra. The study firstly looks into the utility of non-composited single fixed gain radiance calibrated DMSP-OLS products for proposing a method which might help to build a surrogate method for Indian census. Several parameters are considered in this analysis, with detailed focus on population density, total population and proportion of households with electricity access for 35 districts within the state of Maharashtra. Results show that spatial scale plays an important role in selection of the images and gains. Secondly, this study provides a relative assessment of gain setting for the DMSP-OLS images in an urban Indian context. Images with a gain of 50 dB prove suitable for larger areas while those with a gain of 20 dB give better results at a smaller spatial scale. Statistical analysis and residual maps of spatial distribution of total population and population density validate the result.      [本文引用:0] [21] Small Christopher, Elvidge Christopher D, Balk Deborah, et al.Spatial scaling of stable night lights. Remote Sens Environ, 2011, 115(2): 269-280. City size distributions, defined on the basis of population, are often described by power laws. Zipf's Law states that the exponent of the power law for rank-size distributions of cities is near 鈭1. Verification of power law scaling for city size distributions at continental and global scales is complicated by small sample sizes, inappropriate estimation techniques, inconsistent definitions of urban extent and variations in the accuracy and spatial resolution of census administrative units. We attempt to circumvent some of these complications by using a continuous spatial proxy for anthropogenic development and treat it as a spatial complement to population distribution. We quantify the linearity and exponent of the rank-size distribution of spatially contiguous patches of stable night light over a range of brightnesses corresponding to different intensities of development. Temporally stable night lights, as measured by the Defense Meteorological Satellite Program-Operational Line Scanner (DMSP-OLS), provide a unique proxy for anthropogenic development. Brightness and spatial extent of emitted light are correlated to population density (Sutton et al., 2001), built area density (Elvidge et al., 2007c) and economic activity ( and ) at global scales and within specific countries. Using a variable brightness threshold to derive spatial extent of developed land area eliminates the complication of administrative definitions of urban extent and makes it possible to test Zipf's Law in the spatial dimension for a wide range of anthropogenic development. Higher brightness thresholds generally correspond to more intense development while lower thresholds extend the lighted area to include smaller settlements and less intensively developed peri-urban and agricultural areas. Using both Ordinary Least Squares (OLS) and Maximum Likelihood Estimation (MLE) to estimate power law linearity and exponent of the resulting rank-size distributions across a range of upper tail cutoffs, we consistently find statistically significant exponents in the range 鈭0.95 to 鈭1.11 with an abrupt transition to very large, extensively connected, spatial networks of development near the low light detection limit of the sensor. This range of exponents and transition are observed at both continental and global scales. The results suggest that Zipf's Law also holds for spatial extent of anthropogenic development across a range of intensities at both continental and global scales. The implication is that the dynamics of urban growth and development may be represented as spatial phase transitions when the spatial extent and intensity of development are treated as continuous variables rather than discrete entities.      [本文引用:0] [22] Tao Yuan, Xinqi Zheng, Wei Zhou.Calculation methods of territorial development intensity using DMSP/OLS data.

This paper presents a quantitative analysis on the brightness of nighttime lights and territorial development intensity (TDI) from pixel-scale using the land use data of Shuozhou City as the reference data source. The nighttime lights were reprojected to 2-kilometer equal area grid in an Albers conical equal area projection. Linear regression defined a formula for estimating the TDI base on the brightness of nighttime lights. Furthermore, results also confirm that different types of construction land make different contribution to the brightness. This method is effective and convenient for constructed area analysis and monitoring.      [本文引用:0] [23] Wang Wen, Cheng Hui, Zhang Li.Poverty assessment using DMSP/OLS night-time light satellite imagery at a provincial scale in China.

All countries around the world and many international bodies, including the United Nations Development Program (UNDP), United Nations Food and Agricultural Organization (FAO), the International Fund for Agricultural Development (IFAD) and the International Labor Organization (ILO), have to eliminate rural poverty. Estimation of regional poverty level is a key issue for making strategies to eradicate poverty. Most of previous studies on regional poverty evaluations are based on statistics collected typically in administrative units. This paper has discussed the deficiencies of traditional studies, and attempted to research regional poverty evaluation issues using 3-year DMSP/OLS night-time light satellite imagery. In this study, we adopted 17 socio-economic indexes to establish an integrated poverty index (IPI) using principal component analysis (PCA), which was proven to provide a good descriptor of poverty levels in 31 regions at a provincial scale in China. We also explored the relationship between DMSP/OLS night-time average light index and the poverty index using regression analysis in SPSS and a good positive linear correlation was modelled, with Requal to 0.854. We then looked at provincial poverty problems in China based on this correlation. The research results indicated that the DMSP/OLS night-time light data can assist analysing provincial poverty evaluation issues.      [本文引用:0] [24] Zeng Chuiqing, Zhou Yi, Wang Shixin, et al.Population spatialization in China based on night-time imagery and land use data.

Abstract

Since the 1980s Chinese economic reform has greatly accelerated its economic growth while in contrast China's environment is increasingly degraded. The Chinese government has recognized that environmental protection and sustainable economic development can promote mutual and sustainable co-development of the economy and the environment as a basic national principle. This paper examines the interactions between economic development and environmental change in China that were compared and analyzed for the years 1996 and 2000. Net primary production (NPP) was selected as a proxy evaluator of ecosystems and gross domestic product (GDP) was chosen as a proxy evaluator of economic development. An NPP change map was produced with Advanced Very High Resolution Radiometer (AVHRR) summed annual NPP imagery products. The Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime imagery was used to produce a Chinese GDP change map. An integrated map was produced to exhibit the combined changes of NPP and GDP. This map showed that in the regions with increased GDP, NPP decreased but the regions with no GDP change were smaller in area for NPP increase while larger in area for NPP decrease. The changing pattern of NPP varied with the developing level of GDP at province level. A province's development of GDP is controlled by its accessibility to natural resources. Interactions between NPP and GDP are greatly affected by factors of spatial location aside from human factors and natural systems' characteristics.

Research Highlights

? Nighttime imagery is used to estimate GDP at the pixel level. ? Remote sensing is a potential tool to study interactions of social-ecological systems. ? The Changing patterns of NPP and GDP vary by region. ? Globalization leads to uneven outcomes for Chinese social-ecological systems.

Journal of Geographical Sciences, 2011, 21(2): 331-345. Valley economy is a new mode in mountainous area development that is defined by various characters of valley development, and is a distinguishing economical geographic pattern for mountainous area development. The special spatial coupling relations in the distribution of different mountainous elements in valleys are new subjects for the mountain development studies, and such studies are meaningful both for researches and practices. Based on the long term researches on mountainous area development and following a brief exploration into the connotations and the spatial organizing process of valley economy, the authors analyzed the present situations of the development of valley economy in Beijing’s mountainous areas, studied the characteristics and the impacts of the spatial structural changes of the valley economy in Beijing’s mountainous areas, and finally proposed a rational arrangement of the spatial structure of the valley economy in Beijing’s mountainous areas. It is considered in this study that valley economy plays an important role in the development and functional transformation in Beijing’s mountainous areas in the new epoch. Firstly, valley economy is not outlined by the administrative boundaries, and it connects most of the villages in the mountainous areas roughly along the major transportation lines. Therefore, valley economy can exert positive influence on the development in the mountainous areas, at least in the aspects such as the rearrangement of industrial structure in the mountainous areas and the coordinated development of rural and urban areas. In addition, it is found that the valley economy in Beijing’s mountainous areas is evolved in a spatial organizing stage of secondary concentration, which is characterized by resource-saving, ecological protection and industrial optimization. Therefore, the development of valley economy will be helpful to the coordination between ecological protection and economic development in the mountainous areas, and will promote the integrated development of the mountainous areas. The developing mode of the valley economy in Beijing’s mountainous areas will provide the basis for the decision-making in the transformation of the functional roles of Beijing’s mountainous areas, and on the other hand, will present experiences for the studies in the mountainous areas outside of Beijing.      [本文引用:1] [28] Lv Wei, Wang Weitong.Unbalanced development, public services and government responsibility: An analysis based on government preference and government efficiency.
