摘要

[目的] 对贵州省荔波县的生态脆弱性与经济贫困的耦合关系进行研究，为该区域的生态环境建设和经济发展提供科学参考。[方法] 以荔波县为例，以行政村为评价单元，采用敏感性—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，并从经济和社会两个维度，构建村级尺度上的经济贫困的评价指标体系，建立荔波县生态脆弱性和经济贫困耦合模型，由此分析生态脆弱性和经济贫困耦合协调度及其空间分布。[结果] ①荔波县的轻度脆弱和中度脆弱行政村比例较大，中部和南部的生态脆弱性相对较高，东北部的生态脆弱性相对较低。②荔波县中度贫困所占的行政村比例最大，较重度和重度贫困主要分布在东北部和南部。③将荔波县的生态脆弱性与经济贫困的耦合关系分为6种类型，协调同步型的行政村比例仅占10.6%，协调环境滞后型行政村比例最多，主要分布在西部。[结论] 荔波县的生态脆弱性与经济贫困的耦合协调度整体较低，未来发展中，要协调好环境的保护与经济的发展两者之间的关系，促进区域的可持续发展。

Abstract

[Objective] The coupling relationship between ecological vulnerability and economic poverty in Libo County

Guizhou Province

was studied to provide a scientific reference for the ecological environment and economic development of the region.[Methods] Libo County was studied as an example

with single administrative villages taken as the evaluation unit. The sensitivity-resilience-stress conceptual model was selected to build an evaluation index system of ecological vulnerability and construct an economic poverty evaluation index system of the village from social dimensions and economic dimensions. The two evaluation index systems were then combined to establish a coupling model of ecological vulnerability and economic poverty in Libo County

which was analyzed for the degree of coordination and the spatial distribution of the coupling of ecological vulnerability and economic poverty.[Results] ① Libo County had a relatively large proportion of lightly and moderately vulnerable administrative villages

with relatively higher ecological vulnerability in the central and southern regions and relatively lower vulnerability in the northeast. ② In Libo County

the largest proportion of administrative villages had moderate poverty

with comparatively severe poverty mainly distributed in the northeast and the south. ③ The coordination degree of the coupling of ecological vulnerability and economic poverty in Libo County was divided into six types. The proportion of coordinated and synchronous administrative villages accounted for only 10.6% of the total. The largest proportion belonged to administrative villages with a lagging environment

which were mainly in the west.[Conclusion] The coupling degree of ecological vulnerability and economic poverty in Libo County was generally low. In future developments

the relation between environmental protection and economic development must be coordinated to promote sustainable regional development.
