摘　　要：探索禁牧政策背景下农户生计资本与生计结果关系,对提升农户生计和沙漠化逆转的可持续水平具有重要意义。以农牧交错带上典型的沙漠化逆转区宁夏盐池县为例,基于SLA可持续生计框架和实地调研数据,定量评估了农户生计资本与沙漠化逆转趋势,运用灰色关联法和二元Logistic模型探讨了两者间的关系和影响。结果表明:(1)盐池县农户的生计资本存量仅处于维持基本生活需求阶段,金融资本和社会资本储量较低,存在明显的属性差异,各乡镇间差异较小;(2)农户对沙漠化逆转的响应主要表现在生态政策、适应行为、环保意识、环保行为和环境感知5个方面,存在显著的属性差异和空间差异,63.76%的受访户倾向于沙漠化逆转可持续;(3)农户生计资本与沙漠化逆转趋势之间存在较强的关联关系,人力资本和金融资本对沙漠化逆转可持续起负向作用,而物质资本、自然资本和社会资本则呈正向影响;(4)金融资本、社会资本和人力资本是影响沙漠化逆转可持续的关键因素,是今后该县农户生计资本更新与发展、可持续生计能力形成的关键点和突破点。Sandy desertification is one of the most serious environmental problem around the globe, threatening the living and development of nearly 110 countries and 10 million people. It is the product of interaction between ecosystems and social systems. China is one of the most severely countries affected by desertification. Desertification process of agro-pastoral ecotone in northern China has shown a significant reversal trend under the implementation of a series of national ecological protection policies during the past several years. If there is no regulation of ecological policies when we considering the marginal decrease of coercive power of ecological policies and the time limit of ecological compensation project, whether the farmers＇ livelihood capital reserves and combination form can provide more livelihood options to achieve rehabilitation trend sustainably？ It is of great importance to study the relationship of the farmers＇ livelihood capital and livelihood results under the situation of implementing the grazing prohibition policy, for the purpose of improving the sustainability of farmers＇ livelihood and desertification reversion. Yanchi County, desertification reversion in agro-pastoral ecotone. Based is taken as the study region in our study is the typical region of on the sustainable livelihood framework and field survey data, the farmers＇ livelihood capital and the reversion trend of relationship and influence between the above two factors model. The results showed that ： （ 1 ） Farmers＇ livelihoods desertification were quantitatively evaluated, respectively. The were studied using grey correlation analysis and binary Logistic capital stock of Yanchi County is only at the stage of maintaining basic needs with a lack of the financial capital and social capital. There are obvious differences between the farmers while only little differences between the villages. （2） The responses of farmers to desertification reversion mainly lie in ecological policy, adaptive behavior, environmental
