摘　　要：为提高区域恢复力状态、实现可持续发展,以洞庭湖生态经济区为研究对象,选用改进TOPSIS法,探究生态、社会、生产子系统及其综合恢复力的时空分布特征及其驱动机理。研究结果表明:2000—2010年,研究区恢复力状态基本呈现下降趋势,至2018年恢复力状态回归上升趋势;空间分布上,综合恢复力高值集中分布,低值分散分布;恢复力影响因子与恢复力状态之间为线性关系,应采取有效措施,促进区域可持续发展。To improve the state of regional resilience and achieve sustainable development,Taking the Dongting Lake Ecological Economic Zone as the research object,the improved TOPSIS method is selected to explore the temporal and spatial distribution characteristics and driving mechanism of ecological,social,production subsystems and their comprehensive resilience.The research results show:From 2000 to 2010,the resilience status of the social-ecological landscape in the study basically declined,but increased in 2018.In terms of spatial distribution,high values of the comprehensive resilience are concentrated and low values are scattered.There is a linear relationship between resilience influencing factors and resilience status,and effective measures should be taken to promote regional sustainable development.
