    Abstract:

    [Objective] This article analyzed the soil and water conservation measures of Hesheng watershed of Ning'an City in Heilongjiang Province in order to provide technical support for soil and water loss control in hilly area of northeast China. [Methods] Based on the field survey and investigation, land use map and google images, we analyzed the spatial distribution of land use in Hesheng watershed by using ArcGIS 9.3 spatial analysis function. The benefits of soil and water erosion control were evaluated. [Results] The soil erosion control measures in the watershed mainly included terrace plants, soil conservation, erosion ditch protective forest, check dam, ecological restoration, five-hole culvert waterway bridge and culvert. [Conclusion] The economic internal rate of return rate of soil erosion comprehensive treatment project in Hesheng watershed was greater than the social discount rate. Economic net present value was greater than 0, and the benefit-cost ratio was greater than 1. The project meets the requirements of the national standards, and can provide references for soil and water loss control in other regions.
