摘　　要：从水土保持、社会经济发展和生态服务功能等3个方面入手,厘定了"小流域治理度"的概念,结合小流域综合治理目的,在专家意见和参考文献的基础上建立了一套小流域治理度的评价指标体系与方法,并在江西省兴国县选择了塘背小流域进行计算验证。结果表明:评价小流域治理度的3大类19项指标能反映小流域综合治理情况,采用的层次分析法简单实用。塘背小流域经过多年治理恢复,其治理度由治理前的0.252提高到0.683,提高了0.431,增加了1.71倍。The concept of watershed management and recovery degree （WMRD） was defined from three aspects, i.e., soil and water conservation, socio-economic development and ecological service function. An evaluation index system and method for assessing WMRD was established focusing on the purpose of watershed comprehensive management on the bases of expert advices and references. Tangbei watershed in Xinguo country was selected as the study case. The results showed that the selected 19 indicators for assessing WMRD could reflect the real situation of watershed management. The analytic hierarchy process was simple and practical. WMRD of Tangbei watershed increased from 0,252 in 1980s to 0.683 in 2007 after long-term management.
