摘　　要：以广西都安县石漠化治理示范区为例,建立了石漠化生态治理效益的评价指标体系,运用模糊综合评价模型对石漠化生态治理效益进行了评价。结果表明,石漠化治理前生态效益、经济效益和社会效益等级分别为:一般、差、很差;治理后为:一般、一般、良好。石漠化治理前综合评价等级为差,治理后为一般,这说明广西都安县的石漠化治理已取得一定成果。The rocky desertification management demonstration zone in Du＇an County of Guangxi was cited for a case study. An index system was established for evaluation of benefit of ecological management of rocky desertification, using a fuzzy comprehensive evaluation model. Results show that the ecological benefit, economic benefit and social benefit of the unmanaged zone was general, poor and very poor, respectively, and turned out to be general, general and good, respectively after the management. The pre-management zone was graded poor in comprehensive evaluation, and the post-management zone was graded general, which suggests that the management of the rocky desertification in Du＇an County has made certain progress.
