摘要: 处于城市化不同发展水平的城市,其土地集约利用的利用强度、利用形式与利用类型存在显著差异,城市土地利用最佳集约度与城市化水平密切相关,而城市土地集约利用与城市化的耦合协调可有效推动城市可持续发展。基于城市土地集约利用与城市化的交互耦合作用机制,本文构建两者之间的耦合协调发展度模型,定量评价城市土地集约利用与城市化的耦合协调发展状况,并将其分为拮抗、磨合和协调三大阶段9类状态,最后利用ArcGIS9.2对耦合协调发展度进行空间聚类分析,并以环渤海地区27市进行实证研究。结果发现,研究期间内环渤海地区城市耦合协调发展度多处于磨合阶段,没有拮抗阶段,且交互耦合关系随着时间变化而逐渐优化;基于其相对发展状态,环渤海地区城市多处于同步发展状态,滞后发展状态与超前发展状态较少,呈稳定的梭形形态;基于空间聚类系数,城市耦合协调发展度呈先集聚后随机分布,没有空间强极化效应,高值集聚地域为京津冀圈,低值集聚地域则为辽东半岛圈。

Abstract: Land use intensity, land use type and land use form of the intensive urban land use in different cities, which reflect different levels of development in urbanization, have significant differences. What's more, optional intensity of urban land use is closely related to the urbanization level. Based on the coupling mechanism between intensive urban land use and urbanization, to promote the balance between them is the most important basis of achieving sustainable development. Based on the interaction between intensive urban land use and urbanization, we evaluated index of the intensive urban land use coefficient, the urbanization and the harmonious degree quantitatively by factor analysis with the aid of SPSS16, then set up the degree model of harmonious development. We divided the harmonious degrees into the antagonism, the compromise and the coordination, comprising of three stages. Then using the analysis method of dynamic equilibrium relation of time series, this paper analyzed qualitatively the harmonious degrees. Finally, with the aid of spatial autocorrelation of ArcGIS9.2, the spatial clustering analysis in the Bohai Rim Region which consists of 27 cities in 2000, 2002, 2005 and 2007 year is also evaluated quantitatively. The result shows that the coupling harmonious degrees of cities in the Bohai Rim Region are mainly in three states (Ⅳ, Ⅴ and Ⅵ) of the compromise stage but have no antagonism stage. During the study period, the relation between intensive urban land use and urbanization is becoming more and more harmonious. Based on its relative state of development, most cities have remained a synchronized development status, and both of statuses in delay and in advance are much less, which are spindle bacilliform in shape. According to the spatial clustering coefficient, the phenomenon of strong spatial-polarization is still not significant, and the high-value center is in the Beijing-Tianjin-Hebei region, while the Liaodong Peninsula region is the low-value center.
