摘    要:在干旱区内陆河流域,由于水资源过度开发利用,生态环境退化已成为普遍现象.向断流的河道和生态退化区域实施生态输水,是河流生态系统恢复的基本行为和必然过程.基于向塔里木河下游7次生态输水过程中地表水、地下水、植被恢复等系统监测,并运用卫星遥感技术,对生态输水后植被恢复响应特征指标NDVI(植被指数),进行了系统研究分析,并提出植被相对恢复度的评价方法.

关 键 词:塔里木河  生态输水  遥感监测  植被恢复  植被指数

Abstract:There is a common phenomenon of degeneration of ecological environment due to over-exploring and over-using water resources in inland river basin in arid region.To transport water to the dry rivers and areas of ecological degeneration is a necessary process and basic measure for restoring the ecological environment. Based on monitoring data of surface water,groundwater,vegetation restoration in the seven periods of water-conveying in the lower reaches of Tarim River,an appraisal of relative vegetation coverage ranks dependent on the systematic analysis of normalized difference vegetation index(NDVI) by using remote sensing after water-conveying is provided in this paper.
Keywords:Tarim River  water-conveying  remote-sensing monitoring  vegetation restoration  normalized difference vegetation index
