黄土丘陵沟壑区小流域多水源联合配置研究

Study on joint allocation of multiple water resources for a small watershed in the loess hill and gully region

在分析黄土丘陵沟壑区地形地貌、水资源特点、利用现状、生产经营方式的基础上,提出以小流域为尺度的水资源优化配置研究的必要性。以县南沟小流域为研究区,对区域内常规和非常规水资源进行联合配置研究,建立适宜该地区的多目标、多水源联合配置模型。对配置方案的结构、社会发展协调性和用水效益进行分析。结果表明:配置方案结构合理,效益明显,有助于促进区域的社会协调发展。

On the basis of analysis of landscape features, water resources, current water resource use, production, and operation modes, the necessity of optimizing allocation of water resources on a small watershed scale is detailed. Xiannangou was selected as a typical area for the study. The joint allocation of conventional and unconventional waters resources was studied and a joint multi-objective allocation model for multiple water resources was established. Through analysis of the allocation scheme configuration, coordination of social development, and benefits of water consumption, it was shown that the allocation scheme configuration was reasonable and could contribute to coordinated development of society.
