摘要
干旱区内陆河流域的脆弱生态环境是在长期的演变过程中形成的。人类对自然资源 ,特别是水资源的不合理利用 ,加剧了脆弱生态环境的演变过程 ,影响了干旱区的生态安全。从国内外脆弱生态环境研究进展状况以及以塔里木河流域为典型代表的干旱区内陆河流域自然地理特征分析中 ,揭示了脆弱生态环境的特征及演变规律。近一个世纪以来 ,人们针对内陆河流域的人与环境问题、水资源问题 (包括水文地质、水资源变化特征、水环境变化特征 )、气候以及自然地理学领域做了大量的研究工作。随着国家西部发展战略的逐步实施 ,干旱区内陆河流域将成为西部地区重要的资源开发与经济发展潜力巨大的地区。
The fragile ecological environment has been formed for a long time in continental river basin in arid zone. The evolution process is seriously changed along the utilization of natural resources especially water resource by human beings, which affected ecosafety in arid zone. Depending on development of fragile ecological environment researches at home and abroad, based on the analysis of physical geography characteristics in the typical Tarim River Basin, the fragile ecological environment features and evolution patterns are revealed. In the past century, people engaged in some research work in the continental river basin in arid zone. Such as, human beings and environment problem, water resource problems including hydrological geology and water amount change features as well as hydrological environment, climatology and physical geography fields etc. With gradual implementation of national development strategies in the west part, the continental river basin would become an important area that has large potential in resource exploitation and economy development in arid zone.
