蓝绿基础设施多功能对景观格局的时空响应及风险区分级
Spatiotemporal Response and Risk Zone Classification of Multifunctional Blue-Green Infrastructure to Landscape Pattern——A Case Study of Sichuan Tianfu New Area
摘要
Abstract
Urban blue green infrastructure(BGI)provides various types of ecosystem service functions.Studying the relationship between BGI landscape pattern and functions is of great significance for impro-ving urban ecosystem service functions.Taking the Tianfu New Area in Sichuan(including the coordinated administration area)as the research area,using land use data from three periods of 2010,2015,and 2020,the spatiotemporal evolution characteristics of landscape pattern and BGI multifunction were measured,and geographic detectors were used to detect the spatiotemporal response of BGI multifunction to landscape pattern.Finally,based on the detection results,the risk zones with low service function level were classi-fied.The results showed that from 2010 to 2020,the landscape pattern in the study area changed signifi-cantly,with continued intensification of landscape fragmentation,decreased continuity,and a high degree of heterogeneity in the landscape.The multifunctional level showed a trend of first increasing and then decrea-sing,with low service functions spreading from north to south,while high functional levels were concen-trated and distributed in the Longquan Mountains and Pengzushan Scenic Area;The landscape composition type,network structure element type,patch density index(PD),and area weighted average shape index(AWMSI)were the main driving factors affecting the spatiotemporal evolution of multifunctional systems.The interaction between landscape composition type and network structure element type had the greatest impact.The research can provide certain reference for optimizing the landscape pattern and controlling eco-system services in Sichuan Tianfu New Area.关键词
