%X Remote sensing data from Landsat 5 were utilized to assess urban area thermal characteristics in Lanzhou.Estimating urban land use extents and development densities,a major component of the vegetation-impervious surface-soil(V-I-S) model and the Linear spectral mixture analysis method are used to define the different threshold values.According to impervious surface fraction,the urban area is reclassified for four categories.Analysis results show the urban area of Lanzhou has a daytime heating effect.These t...
