摘    要:采用现代化高新技术对流域牛态环境进行动态监测,是流域规划和综合治理的重要依据.本文以塔里木河下游地区的三期遥感影像及基础背景数据为基础,基于遥感和GIS技术,通过分类体系划分、遥感解泽、生态模型构建,实现了塔里木河下游地区多源、多类型监测数据的定性、定量分析.分析结果表明:应急输水工程实施后,随着累计输水最的逐渐增加,塔里木河下游地区的中、高植被覆盖度而积也逐渐增加,非沙漠化和轻度沙漠化面积扩大,而中度沙漠化面积缩小,生态环境趋于好转.

关 键 词:塔里木河  应急输水  生态环境  遥感与GIS

Abstract:Using high technology to monitor of river dynamically is the important basis of the planning and comprehensive reclamation of river basin. The paper takes the tree-period remote sensing images of the lower reaches of tarim river as basic data and realized the multi-source and multi-type monitored data of qualitative and quantitative analysis through classification system, remote sensing interpretation and ecological models based on RS and GIS. The results show that the moderate and high vegetation coverage ...
Keywords:Tarim River  emergent water transfer  ecological environment  remote sensing and GIS
