苏州市吴中区土地利用景观格局变化分析与模拟

在分析苏州市吴中区2005～2008年土地利用变化的基础上,应用CLUE-S模型预测分析了2008～2020年土地利用时空变化情况;从景观生态学的角度,利用景观指数定量分析了未来吴中区土地利用景观格局状况。结果表明,2005～2008年吴中区土地利用变化幅度过大,大量的耕地与林地转换成了建设用地与园地;在节约集约用地与耕地保护政策的导向下,未来土地利用变化幅度将明显减缓;耕地、林地及水域破碎度有所降低,但建设用地破碎度仍有所增加,总体上各景观类型表现为向均衡性方向发展的趋势。

Analysis and Simulation of Land Use and Landscape Pattern Change in Wuzhong District of Suzhou City

Based on analyzing the land use change in Wuzhou from 2005 to 2008, temporal and spatial variation of land use change in Wuzhou from 2008 to 2020 were analyzed and simulated by using CLUE-S, from aspect of landscape ecology, the landscape pattern in Wuzhong District were analyzed by using landscape pattern index. The results showed that the changing extent of land use was too large that a large number of cultivated land forest land change into extent of land use will showed obviously smaller by considering the policy guidance of land saving and intensive use and cultivated land protection. The degree of fragmentation of cultivated land, forest land and water land will decrease but construction land. The general show that all landscape type will have a balanced development.
