甘肃连城国家级自然保护区天保工程二期效益综合评价

选取甘肃连城国家级自然保护区为研究对象，通过调查了解保护区天然林资源保护工程二期实施情况，从生态、经济和社会效益3个层面选取15个评价指标，建立评价指标体系，采用层次分析法（AHP）对甘肃连城国家级自然保护区天然林资源保护工程二期效益进行综合评价。结果表明，在综合评价中权重值表现为：生态效益>社会效益>经济效益，而在15个评价指标中，森林覆盖率权重值最大，生物多样性和森林蓄积量权重值略次之；职工年收入增长率、自然资源开发程度、社会知名度权重值最小，对综合评价的影响较小；三大效益评价值相差较大，生态效益评价结果为一级，经济效益评价结果为四级，社会效益评价结果为一级。评价结果表明，甘肃连城国家级自然保护区天保工程效益综合评价结果为一级，保护区天保工程实施成效显著。

Benefits Comprehensive Evaluation of the Second Phase of Natural Forest Protection Project in Liancheng National Nature Reserve of Gansu Province

This paper investigated the implementation of the second phase of the natural forest protection project in Liancheng National Nature Reserve of Gansu Province, selected 15 evaluation indicators from three levels of ecological, economic, and social benefits, established an evaluation index system, and used analytic hierarchy process (AHP) to comprehensively evaluate the benefits of the second phase of the natural forest protection project in the reserve. The results showed that in the comprehensive evaluation, the weight values were as follows: ecological benefits>social benefits>economic benefits. Among the 15 evaluation indicators, the weight value of forest coverage was the highest, followed slightly by the weight values of biodiversity and forest volume; the weight values of the annual income growth rate of employees, the degree of natural resource development, and the weight value of social awareness were the smallest, which had the small impact on comprehensive evaluation; the differences in the evaluation values of the three major benefits were significant, and the evaluation results of ecological benefit was Level 1, the economic benefit was Level 4, and the social benefit was Level 1. The evaluation results indicated that the comprehensive evaluation of the benefits of the natural forest protection project in the Liancheng National Nature Reserve was Level 1, and the implementation of the project in the reserve had achieved significant results.
