南水北调中线工程建设扰动地表面积、弃土弃渣量巨大,若防护不当将造成严重的水土流失。以京石段应急供水工程(河北段)为例,探讨了水土流失防治的重点地段和措施。京石段应急供水工程水土保持方案及后续设计完备、建设管理体系完善,目前已全部完工并通过了水利部组织的水土保持设施专项验收,水土保持工程质量良好,取得了较好的防治效果。
The construction of the mid-route of the South-to-North Water Diversion Project will disturb the surface area of the project and spoil it with a huge amount of spoil. If it is not properly protected, serious soil erosion will occur. Taking the Beijing-Shijiazhuang Emergency Water Supply Project (Hebei section) as an example, the key sections and measures for prevention and control of soil and water loss are discussed. The project of water and soil conservation of Beijing-Shijiazhuang Emergency Water Supply Project is complete with follow-up design and perfect construction management system. At present, it has completed and passed the special inspection of soil and water conservation facilities organized by the Ministry of Water Resources. The quality of soil and water conservation works is good and good control effects have been achieved.
