保持生态环境与经济建设的协调发展是新阶段国家扶贫开发的重要策略之一.本文以扶贫开发"新纲要"中规划的14个连片特困区714个贫困县为例,基于敏感性-恢复力-压力度(SRP)的概念模型,构建生态脆弱性评价指标体系,从社会、经济两方面构建了县级尺度上的经济贫困评价指标体系,在此基础上,设计了连片特困区生态环境脆弱与经济贫困耦合模型,对研究区生态脆弱性与经济贫困进行了耦合协调度分析.结果表明:"胡焕庸线"能够很好地刻画连片特困区生态环境脆弱性、经济贫困以及两者耦合协调度的空间分布特征,在扶贫开发过程中,应充分考虑"胡焕庸线"对于我国贫困东西格局划分和减贫的影响;连片特困区脆弱生态环境与经济贫困共生共存,应该充分考虑贫困地区生态环境保护的战略意义,通过保护地区生态环境来达到减少经济贫困的目的;研究区一半左右的县市为衰退失调型,且两者不能做到同步发展.
Maintaining the coordinated correlation between ecological environment and economic development is one of the important strategies in the new stage of poverty alleviation and development. Taking 714 poverty-stricken counties in contiguous destitute areas as study areas,this paper designed the ecological vulnerability evaluation indicator system based on the ecological sensitivityresilience-pressure( SRP) conceptual model,as well as the comprehensive poverty evaluation indicators from the perspective of socioeconomic development,so as to build the coupling model to reveal the coupling between ecological vulnerability and economic poverty. The results showed that Hu-Line could act as a feasible partition label to depict the spatial distribution patterns of ecological vulnerability,economic poverty,as well as their coupling degree in contiguous destitute areas,which should be fully taken into consideration the influence of Hu-Line on the east-west pattern classification of national poverty reduction. In addition,there existed a symbiotic positive correlation between ecological vulnerability and economic poverty,therefore,the strategic significance of ecological and environment protection in poverty-stricken areas should be specifically emphasized to reduce economic poverty by synchronously protecting the ecological environment. Approximately half of the counties involved in the study area were in the coordinated type of recession disorders,where the ecological environment quality and the economic development could not be synchronized.
