摘要
本研究系统评估了中国西南边疆民族地区生态脆弱区的农业生态韧性时空演变特征及其影响因素。基于压力-状态-响应(PSR)框架,构建了综合评价指标体系,采用熵值法确定指标权重,并利用空间自相关模型揭示农业生态韧性的空间关联性与分异特征。研究结果表明,2018—2022年,研究区农业生态韧性总体呈上升趋势,空间分布呈现“南高北低、中部隆起”的格局,且表现出显著的正向空间自相关性,表明韧性水平在空间上具有明显的集聚特征。影响因素分析显示,自然条件、土地使用方式、社区参与及政策响应共同驱动了农业生态韧性的区域差异。为提升农业生态系统的适应性与恢复能力,本研究建议通过优化土地管理、增强社区参与及实施基于自然的解决方案,进一步加强生态安全,助力西南边疆民族地区的可持续发展。
This study systematically evaluated the spatiotemporal evolution characteristics and influencing factors of agricultural ecological resilience in ecologically fragile areas of southwest border ethnic regions in China.Based on the Pressure-State-Response(PSR)framework,an integrated evaluation index system was constructed,and the entropy method was used to determine the index weights.The spatial autocorrelation model was employed to reveal the spatial correlation and differentiation characteristics of agricultural ecological resilience.The results show that from 2018 to 2022,the agricultural ecological resilience in the study area generally increased,with a spatial distribution pattern of"high in the south,low in the north,and a rise in the middle",and it exhibited significant positive spatial autocorrelation,indicating that the resilience level has obvious agglomeration characteristics in space.The analysis of influencing factors shows that natural conditions,land use patterns,community participation,and policy responses jointly drive the regional differences in agricultural ecological resilience.To enhance the adaptability and recovery capacity of agricultural ecosystems,this study suggests optimizing land management,enhancing community participation,and implementing nature-based solutions to further strengthen ecological security and promote sustainable development in southwest border ethnic regions.
