基于层次分析法的延安治沟造地土地整治项目综合效益研究

Analysis of Comprehensive Benefits of Yan’an Gully Land Consolidation Project Based on Analytic Hierarchy Process

本研究采用层次分析法,选取粮食单产增加率、旱涝灾害降低率等12个评价指标,构建综合效益评价体系,对延长县2018年治沟造地项目进行综合效益研究。结果表明:延长县215和216子项目各项指标效益均有较大增长。其中,215子项目经济效益、社会效益、生态效益和综合效益分别增加17.28%、47.25%、59.48%和41.14%;216子项目经济效益、社会效益、生态效益和综合效益分别增加22.75%、48.21%、60.80%和49.67%。说明延安治沟造地项目的实施是成功的,本研究采用层次分析法构建的治沟造地项目综合效益评价体系是可行的,对陕北黄土高原丘陵沟壑区其他土地整治项目的综合效益分析具有一定的借鉴意义。

In this study, the analytic hierarchy process was used to analyze the comprehensive benefits of the gully land reclamation project in Yanchang County in 2018. Through the selection of 12 evaluation indicators, such as the increase rate of grain yield and the reduction rate of drought and flood dis-asters, a comprehensive benefit evaluation system is constructed. The results show that: the benefits of various indicators of the 215 and 216 subprojects have increased significantly. Among them, the economic, social, ecological and comprehensive benefits of the 215 subprojects increased by 17.28%, 47.25%, 59.48% and 41.14% respectively;the economic, social, ecological and comprehensive benefits of the 216 subprojects increased by 22.75%, 48.21%, 60.80% and 49.67% respectively. This indicates that the implementation of the gully land consolidation project of the Yan’an is successful. The comprehensive benefit evaluation system for the gully land consolidation project by the analytic hierarchy process in this study is feasible. It has certain reference significance for the comprehensive benefit analysis of other land remediation projects in the hilly and gully regions of the Loess Plateau in northern Shaanxi.
