特定区域生产建设项目水土流失特征与防治技术管理

目的]为了加强水土流失严重区,生态脆弱地区,水土流失重点预防和重点治理区,崩塌、滑坡危险区和泥石流易发区等特定区域生产建设项目水土保持的分类管理。方法]通过对特定区域的水土流失特点及水土流失防治对策,结合有关水土保持法法律、法规和技术标准等拟定水土保持的分类管理要求。结果]提出了特定区域生产建设项目水土流失防治技术要求。主要包括:提高水土流失防治标准和水土保持工程等级,严格控制地表扰动范围,最大限度减轻对区域水土流失影响等。结论]不同区域生产建设项目水土流失防治应该执行特定的防治标准等级、防治工程设计标准等级和水土保持措施综合配置及相应的技术要求。

Management of Prevention and Control Technicals of Soil and Water Loss Resulted by Production and Construction Projects in Special Regions

Objective] To strengthen the classifying management of soil and water conservation program of production and construction projects in serious soil and water loss areas; ecological fragility areas; key prevention and key management areas for soil erosion; collapse, landslide hazard zone and debris flow-prone areas. Methoeds] To develop technical requirements to prevent and control soil and water loss in management of production and construction projects based on characteristics of soil and water loss and control measures in the special regions, and according to the laws, regulations and technical standards for soil and water conservation. Results] We proposed the requirements of technicals to prevent and control soil and water loss resulted by production and construction projects in special regions, such as improving the soil erosion control standards, and soil and water conservation engineering level; strictly controlling the boundaries of surface disturbance; and minimizing the regional impact, etc. Conlusion] Production and construction projects in different regions should take specific soil erosion control standards, and engineering level, as well as comprehensive measures and corresponding technical requirements of soil and water conservation.
