摘  要:
以贵州省典型喀斯特石漠化治理模式为研究对象,选取生态效益、社会经济效益和模式推广前景为评价指标,构建喀斯特石漠化治理模式效益评价指标体系。选择较为典型的喀斯特石漠化治理模式花江"顶坛模式"和清镇"王家寨-羊昌洞小流域治理模式"为评价对象,采用层次分析、分级赋值、综合评价的方法,对2个模式进行了初步评价。结果表明,"顶坛模式"综合效益得分为3.81分,高于王家寨-羊昌洞小流域治理模式效益得分为3.11分,其中生态效益和社会经济效益方面,顶坛模式(4.83分、3.258分)都优于王家寨-羊昌洞小流域治理模式(3.38分、2.531分),模式推广性前景方面顶坛模式(3分)得分低于王家寨-羊昌洞小流域治理模式(3.333分)。评价指标体系具有一定的科学性,对中国西南喀斯特地区石漠化治理具有借鉴与指导意义。

摘  要:
Control mode for typical karst rocky desertification in Guizhou Province,China is selected as the research object.The ecological benefit,the social and economic benefit and the popularization prospect of mode are selected as evaluation indices.Evaluation index system of control mode benefits for karst rocky desertification is established.The Dingtan mode and the Wangjiazhai-Yangchangdong small watershed control mode are selected as evaluation objects.Preliminary assessment on the two modes are carried out by Analytic Hierarchy Process,grading evaluation,and comprehensive evaluation method.Result shows that comprehensive score of Dingtan mode is 3.81,which is higher than the score of Wangjiazhai-Yangchangdong small watershed control mode (3.11) .In the aspects of ecological benefit and social and economic benefit,Dingtan mode (4.83 and 3.258) is superior than the Wangjiazhai-Yangchangdong small watershed control mode (3.38 and 2.531) .In the aspect of popularization prospect of mode,score of Dingtan mode (3) is lower than that of Wangjiazhai-Yangchangdong small watershed control mode (3.333) .Therefore,the evaluation index system has certain science and offers reference and guidance for the karst rocky desertification control in southwest China.
