"Carbon Sink,Landscape Visions,and Ecological Functions":A Multifaceted Assessment for Community Ecological Spaces under a Synergistic Perspective-A Case Study of High-density Communities in Wuhan City
Urban areas with a dense population and concentrated buildings often face difficulties in dealing with landscape fragmentation and improving the ecological efficiency of green space.Examining the potential of green space to have synergies of multiple functions in densely populated area is now recognized as a vital field of study.The objective of this study is to present an in-depth assessment of green space by analyzing the interaction between carbon sink,visual features,and ecological functions.Taking high-density communities of Wuhan City as study cases,this research samples 800 points and creates a 15-minute living circle for each sampling point.It then uses computer vision to investigate landscape visual features,assesses ecological functions using multiple ecosystem services and landscape indexes,and assesses carbon sink using corresponding measurement techniques.The study discovers the synergistic effects of different functional combinations by applying the method of Ecosystem Services Cluster(SOM).The spatially-explicit findings show that there are four different types of service clusters:clusters with abundant vegetation,clusters linking carbon sink,clusters showing ecological coupling,and ecologically vulnerable clusters.These findings offer insights for improving the green spaces in densely populated areas.The suggested assessment framework provides guidelines for optimizing the green spaces in densely populated communities,therefore contributing to the improvement of the quality of life of residents.
