Spatial-temporal evolution of urban heat island in semiarid typical industrial city: a case of Baotou City
摘要
Abstract
Urban Heat Island (UHI) has become a key factor in deteriorating the urban ecological environment.Studying spatio-temporal evolution and the cause of typical area's UHI and quantitatively evaluating the urban heat environment effect caused by rapid urbanization will be conducive to relieve UHI effect and beneficial for urban ecological environment planning.Based on Landsat5 TM and Landsat8 OLI images of Baotou City,Inner Mongolia,China in 2000,2008 and 2015,this paper retrieved the land surface temperature (LST) of Baotou City by mono-window algorithm,and analyzed the spatio-temporal pattem and evolution characteristics of UHI in Baotou City during the last decade,results show as follows:(1) the urban heat island in Baotou was expanding gradually and mainly concentrated in the bare areas,mining areas,city commercial and densely populated area;the spatial pattem of evolution and the expansion of urban were of high consistency;(2) urban heat island effect intensified,but the high temperature area in downtown was greatly reduced from 2008 to 2015;(3) land use type of underlying surface was an important factor to affect the spatial distribution of urban heat island in Baotou;the land surface temperature differed as fellows:bare land ＞ industrial and mining land ＞ construction land ＞ green land ＞ water;(4) the land surface temperature and NDVI showed significant negative correlation,the higher the vegetation index was,the lower the land surface temperature of the city was.关键词
