摘　　要：西部地区在实施退耕还林(草)后,生态环境明显改善,社会效益显著,但在部分地区也面临退耕还林(草)后,因为条件制约,没有更宽经济渠道的情况下,农户出现家庭生活缺乏经济来源保障的困境。因此,研究如何培育退耕还林(草)后续产业,在既有条件下,挖掘潜在优势,培植新的经济增长点,成为退耕还林(草)区迫切解决的问题,在分析甘肃省泾川县退耕还林(草)后的现状及其模式的基础上,提出了适应当地条件的退耕还林(草)模式植被恢复优化,以更好发挥现有退耕还林(草)生态效益、经济效益和社会效益的思路探索。In the western region, the implementation of conversion of farmland to forest （grass）, improved the ecological environment, resulted in significant social benefits. On the other hand, returning farmland to forests in some areas （grass） still faced the challenge because the farmers＇ income mainly depended on the farmland. As a result, how to develop follow-up industries following returning farmland to forest （grassland）, in both conditions, the potential advantages of mining, to cultivate new economic growth points, returning farmland to forests or grass area is an urgent problem in Jingchuan county of Gansu province. Returning farmland to forest （grass）, and its current status on the basis of the model put forward through the effective use of natural resources, precipitation. Returning farmland to forest （grassland） to optimize the pattern of reform in order to better use existing forests （grass） ecological benefits, and to promote economic and social benefits is the key idea on regional exploitation.
