摘要:

以长江中游经济带325个县域为研究单元,利用2000年、2005年和2010年Landsat TM遥感影像解译数据,分析土地利用转型及生态系统服务价值时空演变特征。构建交叉敏感性响应矩阵,分析生态系统服务价值对土地利用转型的敏感程度并进行敏感性分区。结果表明:① 长江中游经济带土地利用空间分布格局与区域地形特征相契合。年综合土地利用变化率高值区集中在武汉和环鄱阳湖城市圈、长株潭城市群及江西省南部;低值区集中在西部和中部山区,分别对应土地利用转型快速和迟缓区。② 森林和农田向其他多数地类转型对生态服务功能的影响均较敏感,其中森林与农田、湿地、水域、荒漠、建设用地间转型,农田与湿地、水域、建设用地间转型最敏感,而草地、水域和荒漠向其他地类转型不够敏感。③ 生态服务价值敏感性分区空间分异明显:森林与荒漠、湿地、水域间转型的高生态敏感区分布较广;森林与建设用地、农田与湿地、水域、建设用地间转型的高生态敏感区分布较小;森林与荒漠、水域间转型的高生态敏感区多集中在山地丘陵区;森林与农田间转型的中、高生态敏感区多集中在平原盆 地区。研究结果可为如何在科学管理土地开发利用的同时实现生态服务功能的延续和提升提供借鉴。

Abstract:

Taking the county of the Middle of the Yangtze River Economic Belt as a basic research unit, this paper analyzes the spatio-temporal pattern features of land use transitions and ecosystem service value(ESV)based on the Landsat TM remote sensing image data of 2000, 2005 and 2010. By constructing the cross-sensitivity response matrix, the sensitivity of ecosystem service value to land use transition is calculated and sensitive areas are divided. The results show: (1) The spatial distribution pattern of the land use in the Middle of Yangtze River Economic Belt is consistent with its topography. The high value areas of annual comprehensive land use change rate are concentrated in the Wuhan metropolitan area, Changsha-Zhuzhou-Xiangtan urban agglomeration, the Poyang Lake metropolitan area and the southern part of Jiangxi Province, while the low value areas are concentrated in the mountainous areas of central and western China, corresponding to the fast and slow areas of land use transition separately. (2) The transitions of forest and farmland to most other land types are more sensitive compared to the other land transitions, during which the transitions of forest to farmland, wetland, water area, desert and construction land are of the highest sensitivity, while the transitions of grassland, water area and desert to the other land types are of less sensitivity. (3) The ESV sensitive areas differ obviously: most of the high ecological sensitive areas of forest transformed to desert, wetland and water area are widely distributed; transitions of forest to construction land, as well as farmland to wetland, water area and construction land present a small distribution; high ecological sensitive areas of forest transformed to desert and water area are mainly distributed in mountainous and hilly areas; while the middle-high ecological sensitive areas of forest transformed to farmland are mainly found in plain and basin areas. The results can provide reference for us on how to realize the continuity and promotion of ecological service functions while simultaneously well handling the scientific management of land use.
