黄河流域陕西片土壤侵蚀预报模型研究

以气候、地质、地形、植被及人类活动 5类因素中的 6个因子为预报因子 ,以陕西黄河流域水蚀区内 5大类型区中 3 3条小流域的实验观测资料和实地调查资料及有关科研单位的研究成果为基础 ,建立了适用于该区域的土壤侵蚀预报模型。据运用该模型对本区域内 4条小流域水土保持遥感普查成果和建模所用 3 3条小流域土壤侵蚀模数进行验证 ,证明该模型具有较高的精度 ,可以在陕西黄河流域水蚀区及条件相近的其他地区推广应用

Study on Soil Erosion Forecasting Model for Shaanxi Region of the Yellow River Basin

It establishes an applicable soil erosion forecasting model by taking 6 factors of 5 elements of climate, geology, topography, vegetation and human activities as a forecasting factor and taking the observed and investigated data from 33 small watersheds of 5 main category regions of water erosion area of the Yellow River basin in Shaanxi and achievements in scientific research of related research institutes as basis. According to the results of remote sensing general survey on soil and water conservation of 4 small watersheds of the region operated by the model and verification of soil erosion modulus of 33 small watersheds used for modeling, it shows that the model has higher precision and can be popularized and applied in water erosion region and other regions with similar conditions of the Yellow River basin in Shaanxi.
