摘　　要：敦煌地区严重的生态环境退化问题,其根源在于对其产生的原因及其演变过程没有科学、统一的认识.尽管近年来政府及有关部门投入了大量的人力物力,采取了一些措施,做了一些研究,但效果并不明显,甚至有人提出将之与古楼兰衰退相提并论.该文认为,敦煌地区生态退化及其演变,无论是地下水位的下降、绿洲与湿地的萎缩等,都是地质科学领域的问题,需要运用地质学思维分析探讨.研究改善敦煌的生态环境退化和治理措施,必须从环境地质、生态地质学的理论和方法去解决.图1,参13.The serious problem of degeneration of eco-environment in Dunhuang area derived from the lack of scientific and unified comprehension or understanding of its cause and process. In Although the government and relevant departments invested a lot of manpower and resources,took some measures and did some research,its effect was not effective and even some scholars equated it with Ancient Kroraina recession. It was believed to be the problems of geological sciences and be analyzed and discussed on geology whether underground water level declined or oasis or marsh shrank in the course of degeneration and evolvement of eco-environment in Dunhuang. Measures to do research on improving eco-environment in Dunhuang must be based on theories and methods of environmental geology and ecogeology. 1fig.,13refs.
