| Abstract: | oil erosion is a major eco-environmental issue in the Three Gorges reservoir area which has caused degradation of environmental quality,low output capacity of ecosystems and restained rural economic development of the region. The key soil and water loss control project identified for the reservoir area since 1989 has been practiced by taking small catchment as basic unit for integrated control and management. Soil and water loss was controlled for an area covering 3594.44 square kilometers upon completion of the first-phase project in the last five years.As a consequence,the environmental quality of the projected area has been apparently improved, living standard of local people raised and potential population carrying capacity of the environment has been developed. |
