针对山丘区水土流失严重、水资源供需矛盾突出的现实,以资源水利用和可持续发展思想为指导,以豫西山区为例对山丘区沟道水资源开发拦蓄工程集流坝关键参数的确定、开发利用模式、运用方式的选择进行分析。确定出适应于山丘区合理的布坝密度、适宜的坝型和蓄水规模等技术参数,并提出集流坝4种运用方式,为山丘区大规模建设雨水集蓄和水土
Aiming at the serious soil and water loss in hill area and the contradiction between supply and demand of water resources, the author takes the idea of resource and water utilization and sustainable development as guidance and the mountainous area in west Henan as an example to study the key parameters The determination, development and utilization mode, the choice of ways to analyze. Determine a reasonable dam density suitable for the hills, suitable dam size and storage size and other technical parameters, and put forward the use of four kinds of collection dam for large-scale construction of hillside rainwater harvesting and soil and water
