摘　　要：胡杨是塔里木河流域荒漠河岸林的建群树种,在胡杨林区进行植被监测,对塔里木河流域生态环境恢复与重建有着极其重要的作用。本研究利用RapidEye影像及地面调查数据对研究区地物特征信息进行了提取,并分析了胡杨林区地物的光谱特征,结果如下:建立了胡杨林区主要地物(胡杨、柽柳、河流、沟渠、裸地、居民地和其它植被)的遥感解译标志,对典型地物在影像上能相互区分的原因进行了解释,同时提取了RapidEye波段的典型地物光谱曲线和面积信息,分析了植被空间分布的特点及规律。为塔里木河流域的植被监测提供一种新的监测手段。Populus euphratica is the dominant tree species of desert riparian forest in Tarim River Basin, the vegetation monitoring in Populus euphratica forest has the extremely vital role in restoration and reconstruction of ecological environment. The study area feature information is extracted by the Rapid Eye images and ground survey data in this study, and analyzed the Populus euphratica forest spectral characteristics of ground objects. The results are as follows ： the remote sensing interpretation signs of major surface features （ Populus euphratica, tamarisk, rivers, canals, bare land, residential and other vegetation remote sensing interpretation signs ） was estab- lished , the reasons that the typical object in an image can distinguish were explained, and extracted the RapidEye band typical spectral curve and area information, analyzes the characteristics and the law of spatial distribution of vegetation. The study may help provide a new means for monitoring for vegetation monitoring of Populus euphratica woodland in Tarim River Basin.
