以敦煌盆地西湖国家自然保护区为研究区,利用3期次TM卫星遥感数据(1990,2000,2010年),在野外调查的基础上构建了研究区湿地遥感解译标志,通过遥感影像处理、空间变异分析、土地覆盖类型之间的相互转化信息等研究方法,获得了湿地萎缩的原因、演化趋势及环境效应。提出了盆地内调整产业结构、农业高效节水、提高人口素质、外流域调水及加强水资源管理等几个方面采取保护对策,对于实现敦煌盆地地下水位逐步恢复、西湖湿地发挥绿色屏障和保护人类赖以生存的栖息环境具有重要的现实作用。

The West Lake National Nature Reserve located in Dunhuang basin was used as the study area. Multi-temporal landsat TM satellite remote sensing data (1990, 2000 and 2010) were applied for constructing wetland remote sensing marks of this area. Through utilizing the mutual transformation information of land cover classifications and methods such as remote sensing image processing, spatial variation analysis, the the cause for the wetland atrophy, evolutionary trend and environmental effect was pointed and the following protective countermeasures were suggested: industrial structure adjustment in the basin, e?cient water saving agricultural methods, population quality improvement, inter-basin water transfer and intensive water resource management. These measures should be highly practical for ground water level restoration in the Dunhuang basin, thus helping the west lake wetland to play the role of a green barrier, and to protect the local human habitat environment as well.
