摘　　要：长江上游广大山丘区社会发展的历史证明：水土流失严重破坏了人类赖以生存的水土资源，影响了当地农业生产的发展。从１９８９年开展实施的长江上游水土保持重点防治工程，６年来以其显著的经济、生态和社会效益说明：水土保持不仅控制土壤侵蚀，改善生态环境，而且维护了自然资源的永续利用，成为支持长江上游山丘区农业持续发展的重要基础工程。The history of social development in the extensive mountainous and hilly districts in the upper reaches of the Yangtze River proves that soil and water loss seriously destroys the soil and water resources and hinders the development of the local agricultural productive forces.The soil and water conservation key control project in the upper reaches of the Yangtze River has been carried out since 1989. Its remarkable economic, ecological and social benefits show that soil and water conservation not only controls soil erosion and improves ecological environment, but also protects sustainable utilization of natural resources. It has become an important basic project that supports the agricultural sustainable development in the mountainous and hilly districts in the upper reaches of the Yangtze River.
