中文摘要	针对秃尾河上游流域土地荒漠化问题,基于地表反照率-植被指数特征空间理论,利用1989年、2002年和2011年TM、ETM遥感数据为数据源,提取该区荒漠化信息,并开展动态监测研究,从中探索该区域荒漠化动态变化特征和规律,为生态环境建设和经济发展提供参考。结果表明:1)地表反照率-植被指数特征空间方法指标简单,易于获取,有利于研究区荒漠化信息提取。2)22年来研究区荒漠化总面积持续减少,程度不断减轻,不同类型荒漠化土地动态度各不相同,并且其重心均有向西北方向移动规律。3)研究区生态环境趋于好转,主要得益于一系列积极的治理沙地措施和政策。
英文摘要	Aiming at land desertification problem in the upper reaches of Tuwei river basin,based on Albedo-NDVI space theory and by adopting 1989,2002 and 2011TM and ETM remote sensing data,desertification information was extracted in this area,and dynamic remote sensing research was carried out,from which the dynamic change characteristics and rules of desertification were found in order to provide reference for the ecological construction and economic development.The results show that:1)The method of Albedo-NDVI space is simple and low-cost for extracting desertification information in this area. 2)In the past 22 years,the total area of land desertification was decreased,and the extent of desertification was alleviated;the different types of land desertification dynamic velocity varied,and the center of land desertification was regularly moved to the northwest direction.3)The ecological environment in the study area is improved,which is attributed to desertification treatment of a series of positive measures and policies.
