摘　　要：林业生态工程在促进山区环境恢复方面发挥着重要的作用,然而对山区经济的贡献,特别是在推进山区减贫方面的作用还很模糊。文中以武陵山区的湘西土家族苗族自治州为例,建立林业生态工程及其经济效果的结构方程模型(SEM),得出:林业生态工程有助于山区总体经济的发展(系数为0.670),推动了山区的基础设施建设(系数为0.759),然而却加剧了山区农户的贫困程度(系数为0.426)。政策制定者对林业工程扶贫作用的忽视不利于林业工程要求的持续性。必须给农户(森林所有者)明确的显而易见的经济利益,才能实现恢复生态和维持生计的双重目标。The relationship between environmental protection and poverty alleviation constitutes the main content of environmental policy,which is particularly important in mountainous areas. Forestry ecological projects play a significant role in promoting environmental restoration,however,its effect on economic growth and poverty alleviation is still unclear. The study chose the Tujiao and Miao autonomous prefecture of Xiangxi as the examples and established the structural equation model of forestry ecological projects and its economic effect. The results showed that forestry ecological projects contributed to the total economic growth（ the coefficient is 0. 670） and infrastructure construction（ the coefficient is 0. 759）; however,it aggregated the poverty level of rural households（ the coefficient is 0. 426）. It goes against the sustainability of forestry ecological projects if the policy makers neglect the poverty alleviation effect of forestry ecological projects,they have to provide the clear and obvious economic benefits for the rural households（ forests owners） so that to achieve the dual goals of ecological restoration and livelihoods improvement.
