县域土地利用/覆被变化对生态环境承载力影响评价——以江苏省建湖县为例

进行了2001～2004年建湖县土地利用/覆被变化对生态环境(包括水环境、大气环境、土壤环境等)及其生态环境承载力影响评价;结果表明,建湖县生态环境承载力呈下降态势;生态环境单要素承载力——水环境承载力属于中等超载、大气环境承载力属于低超载、土壤环境承载力基本属于弱超载;提出了建湖县协调土地利用与生态环境建设的相应措施。

The evaluation On the influence of land utilization/cover to environment carrying capacity in countryside——Take Jianhu Country as a case

The influence evaluations to the eco-environment (including water environment, atmospheric environment and soil environment) have been analyzed from the Land utilization/cover in this research from 2001 to 2004. The result indicated:(1) Jianhu Country's environment carrying capacity had a tendency to drop.(2)The evaluation result of the single eco-environment factor environment carrying capacity showed that the water environment carrying capacity belonged to the medium overloading; the atmospheric environment carrying capacity belonged to the low overloading; the soil environment carrying capacity belonged to the weak overloading basically. On this base, the specific measures with the coordination land utilization and the ecological environment have been proposed.
