摘要
京杭大运河在新时代社会经济发展和生态系统保护中承载着重要的使命,探明其社会生态系统脆弱性演变特征,对地区经济高质量发展和绿色生态廊道建设具有重要意义。文章以京杭大运河沧州段为研究对象,运用VSD评价模型,评估该区域社会-生态系统脆弱性的时空演变特征。结果表明:①研究区社会-生态系统脆弱性在时间上呈先升后降的变化趋势,整体始终处于较高脆弱性水平,脆弱性均值由2012年的0.19上升到2017年的0.27,最终下降到2022年的0.24,波动性明显。②研究区脆弱性的空间分异特征明显,空间分布呈现由最初的“东北低西南高”到“东北高西南低”的变化趋势,高值区逐渐向东部地区集中。
The Beijing-Hangzhou Grand Canal carries significant missions in the social and economic development and ecosystem protection of the new era.Exploring the evolving characteristics of the vulnerability of its social-ecological system is of great significance for the high-quality development of the regional economy and the construction of green ecological corridors.This paper focuses on Cangzhou section of the Beijing-Hangzhou Grand Canal and applies the VSD evaluation model to assess the spatiotemporal evolution characteristics of social-ecological system vulnerability in this section.The results show that:①the vulnerability of the social-ecological system in the study area exhibits a trend of first rising and then falling over time,maintaining a relatively high level of vulnerability on the overall.The average vulnerability increased from 0.19 in 2012 to 0.27 in 2017,and finally decreased to 0.24 in 2022,with noticeable fluctuations.②The spatial differentiation of vulnerability in the study area is significant,with the spatial distribution changing from“low in the northeast and high in the southwest”to“high in the northeast and low in the southwest”,and high-value areas gradually concentrate in the eastern region.
