摘　　要：在介绍南水北调西线工程调水方案、工程所在位置及调水影响所涉及干旱河谷区的基础上,对干旱河谷的分布及其特征进行了详细的阐述。选取大金川河段干旱河谷为典型研究区,以该区河流生态系统为重点研究对象,采用定量定性相结合的方法对西线调水后研究区可能发生的环境影响问题进行初步分析研究,其中包括调水对河道生态用水、水生生物、河岸植被等方面影响因子的分析。可为西线调水工程对干旱河谷区的影响研究提供部分参考依据。On the basis of discussing water diversion scheme ,location and affected regions of dry valley of west-route water transfer project, the distribution and characteristics of dry valley has carried on detailed exposition. By using the method of integrating quantitative calculation and qualitative approach, this paper dealt with main environment impact on the dry valley region of west-route water transfer project with the research focus on river ecosystem of Da jin-chuan river, such as the influences on ecological water requirement, aquatic organisms, vegetation,etc. This present paper also provided some references for the study of west-route water project＇s influence on dry valley.
