A Study on the Dynamic Relationship between Landscape Information and Heat Island Intensity of Urban Growth Patterns—A Case of Five Cities in the Beijing–Tianjin–Hebei City Cluster

Abstract

Urban heat islands (UHIs) endanger the health of urban residents. Different urban growth patterns (UGPs) have different effects on heat islands. However, the dynamic relationship between UGP landscape information and urban surface heat island intensity (SUHII) remains unclear. This study explored the dynamic relationship between SUHII and UGP landscape information through spatial regression and landscape pattern analysis using Landsat imagery and urban construction land data from five cities in the Beijing–Tianjin–Hebei urban agglomeration from 2010 to 2018. The results show that SUHII increase areas overlap with expansion patches, and the edge expansion and outlying areas show a warming effect. The influence of the edge expansion landscape area and pattern on SUHII changes is greater than the other two growth patterns. The relationship between UGPs’ landscape information and SUHII changes varies among cities. The larger the city size, the stronger the influence of landscape information. Among the landscape patterns, the influence of the landscape area and pattern on SUHII change is large and the influence of landscape fragmentation is smaller. Exploring the dynamic relationship between UGP landscape information and SUHII is conducive to optimizing the spatial layout and pattern selection of urban development and providing a scientific reference for sustainable and livable urban development planning.
