喀斯特地区石漠化综合治理蓄水工程布设研究

Study on Design of Water Storage Projects for the Rocky Desertification Control in Karst Areas

蓄水工程是喀斯特石漠化综合治理中小型水利水保工程中的一项重要工程。以毕节鸭池示范区石桥小流域为例,通过实地调查测算分析,进行石漠化综合治理中蓄水工程布设研究,认为提高雨水集蓄利用是解决灌溉缺水的主要途径,蓄水工程是雨水集蓄利用的重要工程措施,同时可解决喀斯特高原山区工程性缺水问题。应因地制宜地布设蓄水工程,蓄水工程与坡面水系工程紧密结合;在蓄水工程布设过程中进行蓄水池墙体稳定性分析和过水断面核算;蓄水工程防渗处理十分重要。

Water storage project is one of the most important engineerings for rocky desertification control.Through the field investigation and analysis of Shiqiao catchment in Yachi Demonstration Area in Bijie,the design of the water storage projects for the rocky desertification control was studied,it was concluded that,to improve the rainwater harvesting and utilization is an important way to solve the shortage of irrigation water,as an important projects for rainwater harvesting and utilization,the water storage projects also solve the engineering water shortage in the karst plateau.The water storage projects should be designed in line with local conditions and be combined closely with slope water system projects;the reservoir wall stability should be analyzed and the cross section be estimated during the design process of the water storage project;and the anti-seepage treatment was very important.
