依据河龙区间晋西北地区多沙粗沙区８ 条一级入黄支流所在县（ 市） ，９０ 年代以来不同的治理进度水平，采用二阶等距抽样调查法，抽选出进行水土保持措施典型调查点，对调查点水土保持措施的各项指标进行了详细的调查核实，并采用面积加权的方法推算到流域，从而初步得出了该区水土保持措施的保存、分布及质量状况，为大面积计算水土保持措施的减洪减沙效益奠定了良好的基础。
According to the different counties and cities of the eight primary and secondary tributaries located in the coarse and grainy area of northwestern Shanxi Province in the Heilong Period, the second-order equidistant sampling survey method was adopted to select the soil and water conservation measures The typical survey points carried out a detailed survey and verification of various indicators of soil and water conservation measures at the survey sites and deducted them into the watershed by using the area weighted method. The conservation, distribution and quality status of the soil and water conservation measures in this area were initially obtained as Large-scale calculation of soil and water conservation measures to reduce floods and sediment benefits laid a good foundation.
