摘要
土壤侵蚀是三峡库区的主要生态环境问题，造成环境质量下降，生态系统输出能力低下，制约了该区农村经济的发展。１９８９年开展的三峡库区水土流失重点防治工程，以小流域为单元实施综合防治，５ａ来一期工程完成治理水土流失面积３５９４．４４ｋｍ２，工程区的环境质量得到明显改善，人民生活水平提高，开发了潜在的环境人口容量。
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.
