摘　　要：以位于三峡库区的杨家沟、戴家沟小流域为案例,在实地调查研究的基础上,深入分析了三峡库区小流域由于自然和人为因素所导致的生态环境功能降低、生态农业发展滞后等实际问题,在技术和模式层面探讨了山地小区域的生态农业发展。以水土保持为导向发展生态农业应立足资源和环境本底,在农民可以接受的农业技术层次和经济发展水平上做文章,最终走生态产业化和产业生态化的可持续发展之路。这对于在山地小区域维持生态系统的功能,协调人地关系,发展生态农业以及提高居民的生活水平,有重要的理论和实践价值。Basing on field investigation of small watersheds of Yangjia and Daijia valley in TGR, this paper analyzed deeply the problems induced by natural and human factors, such as environment degeneration, ecological function depression and lag of ecological agriculture. Taking into account those problems, ecological agriculture towards to preservation of soil and water, which were discussed on lay of varies technologies and models, should introduce many modem technologies according to standard of villagers and economic development, and seek the way of sustainable development on eco-industrialization and industrial ecology finally. Which played an important theoretic and practical role in the harmony of human and nature, maintain of ecological function in small watersheds and the improve of life standard in rural area.
