In view of the lack of comprehensive evaluation and analysis from the combination of natural and human multi-dimensional factors,the urban surface temperature patterns of Changsha in 2000,2009 and 2016 are retrieved based on multi-source spatial data(Landsat 5 and Landsat 8 satellite image data,POI spatial big data,digital elevation model,etc.),and 12 natural and human factors closely related to urban thermal environment are quickly *** standard deviation ellipse and spatial principal component analysis(pca)methods are used to analyze the effect of urban human residential thermal environment and its influencing *** results showed that the heat island area increased by 547 km~2 and the maximum surface temperature difference reached 10.1℃during the period 2000–*** spatial distribution of urban heat island was mainly concentrated in urban built-up areas,such as industrial and commercial agglomerations and densely populated urban *** spatial distribution pattern of heat island is gradually decreasing from the urban center to the *** were multiple high-temperature centers,such as Wuyi square business circle,Xingsha economic and technological development zone in Changsha County,Wangcheng industrial zone,Yuelu industrial agglomeration,and Tianxin industrial *** 2000 to 2016,the main axis of spatial development of heat island remained in the northeast-southwest *** center of gravity of heat island shifted 2.7 km to the southwest with the deflection angle of 54.9°in 2000–*** center of gravity of heat island shifted to the northeast by 4.8 km with the deflection angle of 60.9°in 2009–*** the whole,the change of spatial pattern of thermal environment in Changsha was related to the change of urban construction *** the pca method,it was concluded that landscape pattern,urban construction intensity and topographic landforms were the main factors affecting the spatial pattern of urban thermal environmen
