摘要
采用长时间多源遥感数据对塔里木河重要生态功能区进行了土地利用变化、植被指数分析,同时结合多年地面调查监测数据,系统分析了区域生态环境变化情况,并对近五年区域生态环境质量开展了评价,环境质量变化值ΔI为2.58,生态环境质量略有下降,其中环境状况指标和植被覆盖率指数起主导作用。
Using the multi-source remote sensing data many years,analyzed land use change and vegetation index of the Tarim important ecological function zones,combined with many years ground investigation monitoring data,systematic analyzed the changes in the regional ecological environment,and evaluated regional ecological environmental quality last five years.Results showed environmental quality changes value ΔI was 2.58,the ecological environmental quality was a slight decrease,the environmental status indicators and vegetation cover index plays a dominant role.
