GIS-InVEST模型联合的固安县热缓解效应评估分析
Evaluation and Analysis of Heat Mitigation Effect in Gu'an County Using GIS and InVEST Models
摘要
Abstract
Quantifying the spatiotemporal evolution characteristics of land use and the cooling effects of different land types has practical significance for optimizing urban ecological patterns.Taking Gu'an County as the research object,this study analyzes the spatial distribution characteristics of land use from 2010 to 2023,evaluates the urban cooling capacity based on the InVEST model,and analyzes the heat mit-igation effects of different regions.The research results indicate that:1)From 2010 to 2023,the compre-hensive dynamic degree of land use in Gu'an County shows a downward trend,the speed of land use change gradually slows down,rural construction land is inefficient,and the ecological spatial structure is insufficient.2)The heat mitigation index of towns is better than that of towns,and areas with abundant green spaces and water bodies such as Qugou Township,Niutuo Town,and Gu'an Hot Spring Leisure Business Industrial Park have relatively higher heat mitigation indices.3)There are significant differences in heat mitigation effects among different land use types,with forest land being the best,followed by wa-ter bodies,and construction land being the worst.The urbanization process in Gu'an County presents the characteristic of intensified heat island differentiation.It is urgent to construct a sustainable development model that optimizes blue-green space and coordinates urban-rural regulation.关键词
