针对本工程项目及项目区的特点,结合防治分区,通过查阅资料和实际调查,按照相关规范和技术审查要点的要求,确定了水土流失预测范围、单元、时段、内容及方法,基于已有试验研究成果,分析确定了各预测单元各个时段的背景值和扰动后土壤侵蚀模数等参数,最后计算了各预测单元和各预测时段的水土流失总量及新增水土流失量,明确了水土流失重点时段、重点区域,以其为水土流失防治措施布设、施工进度安排和监测提供指导意见。
According to the characteristics of the project and the project area, combined with the prevention and control zoning, the range, unit, period, content and method of soil erosion prediction were determined according to the requirements of the relevant norms and technical review points by referring to the data and the actual investigation. Based on the existing tests Research results, the background values of each prediction unit and the soil erosion modulus after disturbance were analyzed and determined. The total amount of soil and water loss and the amount of newly added soil and water loss in each prediction unit and each prediction period were calculated, and the soil and water loss Key period, key areas, with its guidance for the layout of soil and water loss prevention and control measures, construction schedule and monitoring.
