Abstract

The surface temperature(LST)of Dali City was inverted using Landsat remote sensing images between 2006 and 2016.Using the morphological spatial pattern analysis(MSPA)technique,multiple linear regression and geographically weighted regression were utilized to study the coupling connection between forest landscape morphology and the temperature environment in Dali.The findings found that:1)LST in Dali City grew significantly between 2006 and 2016,and there were seasonal variations in the forest landscape and thermal environment,with the strength of several factors altering according to the season:autumn>summer>spring>winter.2)The spatial morphological pattern of the forest landscape had a substantial impact on the thermal mitigation features,which were:core>branch>edge>bridge>perforation>islet>loop in 2006 and core>branch>edge>perforation>islet>loop in 2016.3)The GWR model outperformed the OLS model in terms of reflecting the dynamic interaction between forest landscape and thermal environment.Throughout the urbanization process,the landscape plan may be altered in conjunction with the real circumstances to alleviate the phenomena of urban thermal environment.

Key words： thermal environment; forest landscape morphology; MSPA; Dali City
