摘　　要：基于PSR理论构建贫困地区生态—经济脆弱性评价体系,以韶关市8个贫困县为案例地分析其脆弱性时空格局并探讨耦合度和障碍因子,研究发现:(1)生态脆弱性整体呈“U”型走势,经济脆弱性呈匀速下降趋势,生态—经济脆弱性呈倾斜且平滑的“L”型阶段性下降趋势。(2)县域生态脆弱性空间差异较大,经济脆弱性空间差异缩小,生态—经济脆弱性形成“东高西低、中部适宜”的格局。(3)大部分地区生态—经济耦合脆弱性在中度水平以下,耦合度较高的县主要集中在中部片区。(4)经济总量及产业结构是影响该地区耦合脆弱性的主要障碍因子,年降水、气温和森林覆盖率等生态状态指标是基础障碍因子,环境污染和生态破坏的响应指标重要性有所提升。Based on the PSR theory,a vulnerability assessment system of eco-economic system coupling in povertystricken areas is constructed,taking 8 poor counties in Shaoguan as cases,this paper analyzes their vulnerability space-time pattern and discusses their coupling degree and factors.The results showed that:(1)the overall ecological vulnerability shows a U-shaped trend,showing a wide“U”type;the economic vulnerability shows a uniform downward trend,which has a phased downward trend,showing a sloping and smooth“L”type.(2)The spatial differences of ecological vulnerability among counties are large;the spatial differences of economic vulnerability are shrinking;the eco-economic vulnerability forms a pattern of“high in the east,low in the west and suitable in the middle”.(3)the eco-economic coupling fragility in most regions are below the moderate coupling level,and the counties with high coupling degree are mainly concentrated in the central region.(4)The economic aggregate and industrial structure in the region are the main obstacle factors affecting the coupling vulnerability of the region,the ecological state indicators such as annual precipitation,temperature and forest coverage are the basic obstacle factors,and the response indicators to environmental pollution and ecological damage become more and more important.
