运用生态地质学系统方法，通过对敦煌盆地内生态地质环境问题进行调查分析，主要存在月牙泉湖水位下降、天然绿洲和湿地萎缩，以及土地盐渍化、沙漠化等缓变型地质灾害。结合干旱区生态特征分析认为农业生产与水系统循环密切关联，水土平衡矛盾是主要控制因素。恢复敦煌河道自然水循环系统，建立合理水土的开发利用方式，是缓解盆地内上述地质环境问题的有效对策。

The ecological and geo-environmental problems were investigated and analyzed for the Dunhuang basin through methods of eco-geology system and the existing ecological problems were considered to include exhaustion of the Crescent Lake, shrinkage of the oasis and wetlands and land desertification, which are closely associated with agricultural production and the water circulation system thereof. The contradictory balance between soil and water was regarded as the main controlling factor and effective measures to alleviate these problems are here proposed, such as restoring the natural water circulation system of river in Dunhuang and ensuring the rational development and utilization of soil and water.
