中文摘要：

水文资料、特别是径流资料缺乏是目前我国在水利水电工程建设、水资源综合规划、水资源配置过程中经常困扰勘测设计单位的问题。在都匀市水资源配置研究过程中,针对其径流资料缺乏的问题,通过构建SWAT分布式水文模型,对都匀市境内各干支流流量进行模拟,较准确的得到了都匀市各分区的水资源量及其年变化情况,为水资源优化配置提供了坚实的基础,也为水文资料、特别是径流资料缺乏的地区的水资源管理提供了一个可借鉴的思路和方法。

英文摘要：

The lack of hydrological data, especially those of runoff data, is currently a problem that often puzzles the exploration and design units. In the process of water conservancy and hydropower project construction, this paper plans water resources and water resources allocation comprehensively. During the study of water resources allocation, the problem of lack of runoff data is focused on. The flow of mainstream and tributaries in Duyun is simulated by constructing the SWAT distributed hydrological model. In this way, we have accurately obtained the water resources quantity and the age change in different areas, which provides a solid foundation not only for the optimal allocation of water resources hut also the idea and method for the management of water resources in the areas lacking hydrological data, especially runoff data.
