长三角城市群生态系统服务价值与景观格局演变特征
Evolution characteristics of ecosystem service value and landscape pattern in the Yangtze River Delta urban agglomeration
摘要
Abstract
The rapid urbanization in the Yangtze River Delta urban agglomeration has significantly trans-formed regional ecological landscape patterns,consequently impacting ecosystem service functions.Using land use data from 2010,2015,and 2020,this study employs land use dynamics,landscape pattern in-dices,and Ecosystem Service Value(ESV)assessment methods to analyze decadal land use changes,ESV evolution trends,and landscape pattern characteristics amid natural and human-induced disturb-ances,and provides a scientific foundation for regional ecological conservation and sustainable develop-ment.The results reveal:(1)Land use changes exhibited a stable trend with a decelerating growth rate.Farmland and forest remained the dominant land types,while farmland-to-construction land conversion was prominent,albeit with a declining expansion rate of construction land.(2)Water bodies served as core carriers of regional ecosystem services,with high ESV zones concentrated in hydrologically favorable areas such as Taihu Lake,Chaohu Lake,and the Yangtze River Basin,whereas low ESV areas coincided with dense farmland and construction land clusters.(3)Rapid urbanization-driven construction land ex-pansion and concurrent natural landscape shrinkage significantly weakened ESV provisioning capacity,exacerbating landscape fragmentation and habitat degradation,which underscores the imperative to priori-tize the core habitat conservation.关键词
