基于AHP的丹江流域生态修复模式评价指标优选

以丹江流域生态、工程、生态与工程结合、生态移民等4种生态修复模式为评价对象,采用专家咨询、查阅文献、理论分析相结合的评价方法,从生态修复模式产生的生态效益、社会效益、经济效益三方面,按4个层次初步构建丹江流域生态修复模式评价指标体系。运用专家打分法和层次分析法相结合的方法对初步选择的评价指标进行定量分析,计算各个指标的权重,并进行定性分析,对初选指标进行分析、筛选、优化。最终,舍弃了劳动生产率、收入递增率和地表径流模数指标,得到最终的评价指标为土壤侵蚀模数、植被覆盖率、泥沙拦截量、蓄水保土、人均纯收入、人均产粮、劳动力利用率。

Index Optimization of Pattern of Ecological Restoration in the Danjiang River Basin Based on AHP

Taking Danjiang River basin eco-mode,mode of engineering,ecology and engineering models,models for evaluation of ecological migration as evaluation objects,combining the expert advice,literature review,an analysis of the theory of method of evaluation,from ecological restoration of patterns produce ecological,social and economic benefit,according to the 4 level building evaluation index system of the Danjiang River ecological rehabilitation mode to establish an evaluation system of ecological rehabilitation.It used expert marking method and analytic hierarchy process of combining quantitative analysis method on the evaluation of the initial selection of indicators,calculated the weights of the various indicators and qualitative analysis,the primary indicators for analysis,filtering and optimization.Eventually,it gave up the rate of increasing labor productivity,income and surface runoff modulus index and obtained the final evaluation for soil erosion modulus of sediment,vegetation cover,interdiction,water conservation and the per capita net income per capita grain and labor utilization.
