| Abstract | The northern region of loess plateau in China is a typical fragile ecosystem with serious soil and water erosion. Research into soil erosion prediction is urgently required for this region. However, due to the geography, social and economic conditions, the application of prediction models developed in other countries is limited. Hence, there is a need to develop local prediction models. This project used the Liudaogou watershed, which is located in a cross zone of water-wind erosion on the northern loess plateau in China, as the study area. The landform surface material composition, slope gradient and land utilization were selected as cartographic layers with relevance to soil erosion. Ecological landform units were identified using these layers. For the Liudaogou watershed, there 83 different ecological landform units were identified scattered in 284 plots. Soil erosion would found to occur on waste land, slope land and sparse shrub land with slope gradients of 15-25°. These area represent about 50% of whole watershed. |
