| Abstract: | A distributed model of soil erosion and sediment yield is applied to the numerical simulation made on the process of runoff and sediment transportation for different soil and water conservation measures under various land-use conditions by taking Heicaohe Watershed in Shannxi Province as the study case, and then the benefits from reduction of sediment and runoff for different soil and water conservation measures under various land-use conditions are evaluated through the relevant comparison; which can provide scientific basis and technical support for making the soil and water conservation measures and optimizing the management of the watersheds concerned. |
