The Three Gorges Project is one of the largest hydro--projects in the world and has drawn manydebates inside China and abroad. The major concern is that sediment load from the river basin mayeventually fail the functions of the project for flood control and power generation. To reducesedimentation in the reservoir, watershed management has been adopted. However, there is limitedinformation regarding the effectiveness of various control measures such as terracing and afforestationon a watershed scale. The Jialing River, a main tributary of the Yangtze River, contributesapproximately 25% of the total sediment load in the main river but only represents 8% of the wholebasin area. There have been various land use patterns and extensive human activities for thousands ofyears in the Jialing River watershed. Based on analysis of the major factors affecting erosion in theJialing River watershed, the main watershed management strategies (afforestation, farming andengineering practice) are illustrated, and their e The Three Gorges Project is one of the largest hydro - projects in the world and has drawn manydebates inside China and abroad.
