【摘要】：研究贫困地区脆弱生态环境与贫困的耦合关系是统筹扶贫开发与生态环境保护的基本前提.以典型特困连片区——武陵山特困连片区为例,从地区生态问题出发,利用空间主成分分析方法剔除各指标之间的相关性,对研究区生态环境脆弱性进行了整体评价;在此基础上,构建了生态建设—扶贫开发耦合协调度模型,计算了两者的耦合协调度.结果表明:研究区扶贫开发与生态建设耦合协调程度较低,国家级贫困县多为扶贫开发落后型,非国家级贫困县以生态建设落后型居多.研究得出了在扶贫开发过程中需要注意生态环境保护的结论.
[Abstract]:The study of the coupling relationship between fragile ecological environment and poverty in poor areas is the basic prerequisite for the overall development of poverty alleviation and ecological environment protection. Taking the typical special poverty area of Wuling Mountain as an example, using spatial principal component analysis (spatial principal component analysis) method to eliminate the correlation between the indexes, the ecological environment vulnerability of the study area was evaluated as a whole. On this basis, the coupling coordination degree model between ecological construction and poverty alleviation and development is established, and the coupling coordination degree between the two is calculated. The results show that the degree of coupling and coordination between poverty alleviation and ecological construction in the research area is low. The poor counties in the national level are mostly backward in poverty alleviation and development, while the poor counties in the non-national level are mostly in the backward type of ecological construction. The conclusion is that attention should be paid to the protection of ecological environment in the process of poverty alleviation and development.
