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.
To study coupling between ecological vulnerability and poverty alleviation in poor areas is the basic premise of co-ordinate ecological construction and poverty alleviation. Taking Wuling Mountain destitute as typical study areas, based on the study of Wuling Mountain destitute areals ecological problems, we construct the evaluation index system of ecological fra-gility of the study based on the framework of Sensitivity-Restoring force- Pressure, remove the correlation between the evalua-tion-index by space principal component analysis （SPCA） 〉 and evaluate the study areals ecological vulnerability. We construct the coordination model between ecological construction and poverty alleviation, and calculate the coupling coordination degree. The result shows that the study areals ecological vulnerability is not very well state-level poverty-stricken countries mainly poverty alleviation backwardness type, while the non-national poverty countries are mainly ecological construction behind type. The research draws the conclusion that we should pay attention to the protection of the ecological environment in the process of poverty alleviation and development.
