长三角一体化示范区2000-2020年生态韧性时空分异研究
Spatiotemporal differentiation of ecological resilience in the Yangtze River Delta Integrated Demonstration Zone from 2000 to 2020
摘要
Abstract
Given the limited research on the spatiotemporal differentiation of ecological resilience at the township scale,this study takes the Yangtze River Delta Integrated Demonstration Zone(YRDIDZ)as a case study.Based on the"Pressure-State-Response"framework,an evaluation index system for regional ecological resilience was estab-lished,and spatial principal component analysis was employed for comprehensive assessment.The results show that(1)from 2000 to 2020,the mean ecological resilience of the area decreased from 0.604 4 to 0.566 0,with an overall decline of 6.35%.Qingpu District exhibited a fluctuating upward trend,while Wujiang District and Jiashan County showed a continuous decline.(2)Areas with high ecological resilience were mainly distributed in the central part of the area,whereas low-resilience zones were concentrated in the built-up areas of Qingpu,Jiashan,and Wujiang,showing evident expansion alongside urbanization.Furthermore,the ecological resilience levels of Wujiang District and Jiashan County dropped from the relatively high before 2010 to the moderate by 2020,while Qingpu District re-mained at a moderate level throughout the period.The findings provide a reference for supporting high-quality devel-opment and ecological conservation in the demonstration zone.关键词
