摘要
脆弱性研究是探究系统内部要素和机制的重要方式,乡村地域系统脆弱性研究对促进乡村地区可持续发展具有重要意义.文中以甘肃省85个县域为研究单元,结合VSD分析框架,从社会、经济、生态角度构建甘肃省乡村地域系统脆弱性的评价指标体系,并定量测度2007-2021年各县域乡村地域系统脆弱性,划分脆弱性类型,揭示其时空分异特征.结果表明:1)甘肃省县域乡村地域系统脆弱性指数整体呈"东南高、西北低"的格局,形成以兰州市为核心的高脆弱圈层.2)各子系统脆弱性格局差异显著,社会子系统脆弱性的空间分布趋于碎片化且变化明显,经济子系统脆弱性呈空间集聚特征且变化较小,生态子系统脆弱性空间异质性较强.3)共有8种乡村地域系统脆弱性类型,其中双系统共脆型县区居多且分布零散;强综合脆弱型与弱综合脆弱型县区集中分布;单系统脆弱型的县区数量为:经济脆弱型(17个)＞生态脆弱型(10个)＞社会脆弱型(2个).
Abstract
Research on the vulnerability in an important way to explore the internal elements and mechanisms of the system.The study of rural regional system vulnerability is of great significance to promote the sustainable development of rural areas.This study takes 85 counties in Gansu province as the research units,combined with the Vulnerability Scoping Diagram(VSD)analysis framework,constructs an index system for evaluation of the rural regional system vulnerability in Gansu province from the perspective of society,economy and ecology,and quantitatively measures the vulnerability of rural regional system in each county from 2007 to 2021,divides the vulnerability types,and reveals its spatial and temporal differentiation characteristics.The results indicate that:1)The vulnerability index of county rural regional system in Gansu province is higher in the southeast and lower in the northwest as a whole,forming a high vulnerability circle with Lanzhou as the core.2)The vulnerability patterns of each subsystem are significantly different.The spatial distribution of the vulnerability of the social subsystem tends to be fragmented and changes significantly.The vulnerability of the economic subsystem shows spatial agglomeration characteristics and changes little,and the spatial heterogeneity of the vulnerability of the ecological subsystem is strong.3)There are 8 types of rural regional system vulnerability,among which the coun-ties with vulnerability in double systems are the majority and scattered,the counties with strongly and weakly comprehensive vulnerability are distributed concentratedly,and the number of counties with vulnerability in single system is:economic vulnerability(17)＞ecological vulnerability(10)＞social vulnerability(2).
