摘要: 文章在构建能源富集区社会—生态系统韧性研究理论框架基础上,以陕北能源富集区榆林市为例,采用集对分析、相关分析等方法,从生态、经济和社会3个子系统和脆弱性与应对能力2个方面入手,评估1998—2020年区域社会—生态系统韧性,揭示其韧性演化规律与机理。结果表明:①1998—2020年榆林市社会—生态系统脆弱性指数由0.427波动上升至0.494,应对能力指数由0.248上升至0.798,韧性指数由0.326上升至0.664,区域社会—生态系统韧性是脆弱性与应对能力相互作用的结果。②社会生活子系统脆弱性对总系统脆弱性的作用呈现上升趋势,各子系统应对能力对总系统应对能力的贡献均呈上升趋势。总应对能力对系统韧性起决定性作用,其中经济生产子系统和社会生活子系统应对能力的影响突出。③各影响因子对榆林市社会—生态系统韧性演化的作用性质、速率和规律存在显著差异,呈现近线性、非线性2种影响方式和近线性递增或递减、U型或倒U型递增或递减6种曲线类型。④在自然生态约束、社会经济转型驱动和能源市场变革等内外部因素作用下,区域社会—生态系统呈现由农牧型向能源型进而迈向绿色型的转型发展态势。

Abstract: Based on the construction of a theoretical framework of the socio-ecological system resilience in energy-rich areas,this paper takes Yulin City,an energy-rich area in northern Shaanxi,as the research area,and uses the methods of the set pair analysis and the correlation analysis to measure the regional socio-ecological system resilience from two levels of vulnerability and response capacity and three subsystems of ecology,economy and society in 1998-2020,it reveals the evolution law and impact mechanism of regional socio-ecological system resilience. The results show that: 1) From 1998 to 2020,the vulnerability index of the socio-ecological system in Yulin City fluctuated from 0.427 to 0.494,the response capacity index increased from 0.248 to 0.798,and the resilience index increased from 0.326 to 0.664. The regional socio-ecological system resilience is the result of the interaction between vulnerability and response capacity. 2) The contribution of social life subsystem vulnerability to the overall system vulnerability is on the rise,and the contribution of each subsystem's response capacity to the overall system's response capacity is on the rise. Total response capacity plays a decisive role in socio-ecological system resilience,with the impact of economic production and social life subsystem's response capacity being prominent. 3) There are significant differences in the nature,rate,and law of the impact of various impact factors on the evolution of the socio-ecological system resilience in Yulin City,presenting two types of impact: near linear and nonlinear,and six types of curve: near linear increasing or decreasing,U-shaped or inverted U-shaped increasing or decreasing. 4) Under the coupling effect of multiple internal and external factors such as natural ecological constraints,socio-ecological transformation drive,and energy market reform,Yulin's socio-ecological system presents a transformation and development trend from agricultural and pastoral type to energy type,and then to green type.
