无锡土地利用变化及生态系统服务价值研究

选取江苏省无锡市作为研究区域,探索从2000年到2014年,无锡土地利用状况及生态系统服务价值的变化。对无锡市的发展状况进行评估并对未来的城市发展做出相应的分析。结果表明,无锡市土地大多数是从其他土地类型转变为建设用地;在水域、耕地、林地这3种土地利用类型中,仅有林地有少幅增加;建设用地是变化量最大的土地利用类型,也是最快的类型,可见无锡的城市化进程在这14年中迅猛发展;而在生态系统服务价值方面,无锡的生态系统服务价值也是逐年递增的,但总体变化幅度不大。

Study on land use change and ecosystem services evaluation of Wuxi

Based on the changes of land use and the value of ecosystem services, in this study we selecte Wuxi City, Jiangsu Province as the research area, and explore the change of land use status and ecosystem service value in Wuxi from 2000 to 2014. The assessment of the development for Wuxi City and the analysis of future development are carried out. The actual results show that most of the land in Wuxi is transformed from other land types to construction land. In the three types of land use types, such as waters, cultivated land and forest land, there is only a slight increase in forest land. Construction land is the largest change and the fastest type in the type of land use. it reverls the process of urbanization in Wuxi in the 14 years of rapid development. In terms of the value of ecosystem services, the value of ecosystem services in Wuxi increases year by year, but the overall change is not significant.
