我国是世界上水土流失最严重的国家之一,尤其以黄土丘陵沟壑区流失面积最为广阔,程度和危害最为严重。通过对会宁北部供水工程水土流失特点的分析和总结,依据本工程所处的地貌环境,将项目区划分为多个防治区域,结因地制宜、因害设防,工程措施、植物措施、临时措施合理配置、统筹兼顾,形成了完整的综合防护体系,为类似工程的设计提供参考和借鉴。
China is one of the countries with the most serious soil erosion in the world. In particular, the area of loss in the gully region of the Loess Plateau is the most extensive with the greatest degree of damage and the worst damage. Based on the analysis and summary of the characteristics of soil and water loss in the water supply project in the north of Huining, according to the geomorphological environment in which the project is located, the project area is divided into a number of prevention and control areas. The project area is adapted to local conditions and due to hazards, engineering measures, plant measures and reasonable interim measures Configuration, overall planning, forming a complete integrated protection system for the design of similar projects to provide reference and reference.
