Abstract：Inordertoexplorethe spatialheterogeneityofurban thermalenvironmentanditsresponse todrivingfactors，the LandSurface Temperature （LST）during the heat wave in Guangzhou in2O2 is taken as theresearchobject，andthe Ordinary Least Squares （OLS）and Geographically Weighted Regression （GWR） model are used to analyze the influence ofspatial form， land use and social development factors on the thermal environment. The results show that the of the GWR model is 0.6， and the ofthe OLS modelisonly0.3.The relationship performance between the driving factors ofthe GWR fitingand the thermal environment is better.Buildingdensityproportion of impervious surface androad length arepositively corelated with LST. Theaverage valueofDEMand vegetationcoverage are negativelycorelated withLST.Thecorelationbetweenbuildingheight meanandstandarddviation，DEMstandardeviation，NightieLightIndexandLSTisdiferentindifenttemperaureones. The results can provide scientific basis for optimizing the urban layout and aleviating the heat island effect.
