塔里木河干流生态效应评价方法研究

Research on Ecological Effect Evaluation Method in the Mainstream of Tarim River

以塔里木河干流为研究区,合理选取生态效应评价指标,根据塔里木河流域地表覆盖信息的动态时空变化特征,采用地面监测与多源卫星监测相结合的方法,建立了生态环境变化的监测体系。从植被恢复响应、生态景观格局指数、地下水埋深等方面出发,分析了研究区生态环境本底状况,从而对塔里木河干流生态效应进行了评价。

In this paper, taking the mainstream of the Tarim River as the study area, choosing reasonable evaluation indexes of the ecological effect, using the method combining ground monitoring and multi-source satellite monitoring, according to the dynamic spatio-temporal change characteristics of surface cover information in Tarim River basin, we established a monitoring system of ecological environment change. And then, we analyzed the background of ecological environment in study area form vegetation repair response, ecological landscape pattern index,groundwater depth, so as to evaluate the ecological effect in the mainstream of Tarim River.
