摘要
土壤流失量计算是生产建设项目水土保持方案报告中的一项重要内容,计算结果的准确性关系到水土保持措施布设的合理性。以武汉某点型项目为例,对比分析了类比法和《生产建设项目土壤流失量测算导则》方法(以下简称“《导则》法”)的优缺点。结果表明:①《导则》法中各测算公式综合考虑了水土流失影响因素,比类比法更能反映出项目的实际情况;②利用《导则》法测算所得的原地貌侵蚀量比实际偏小,扰动后侵蚀量与实际较为相符;③《导则》法应用范围更为广泛,不仅适用于水土保持方案,还可适用于水土保持监督管理、行政执法、大尺度水土流失动态监测等领域。
Soil erosion calculation is an important content in water and soil conservation plans for production and construction projects.The accuracy of the calculation directly influences the design of soil and water conservation measure.Taking a point project in Wuhan as a case study,we compared and analysed the advantages and shortcomings of the analogy method and the Guidelines for Soil Erosion Measurement in Production and Construction Projects(hereinafter referred to as the“Guidelines”method).The results show that:(1)Calculation formulas in the Guidelines method account for a broader range of factors affecting water and soil erosion,hence better reflecting the actual situation of the project compared to the analogy method.(2)Soil erosion in the original landform calculated by the Guidelines method is smaller than the actual,but the soil erosion after disturbance is consistent with the actual.(3)The Guidelines method have a broader application scope extending from soil and water conservation scheme to supervision and management,administrative enforcement and dynamic monitoring in large-scale water and soil erosion.
