Abstract
ABSTRACTLand surface temperature (LST), regional evapotranspiration (ET), build-up land information, vegetation information, and other land surface parameters are of great significance for urban scientific planning and urban ecosystem restoration. Taking Fuzhou City as an example and gaining the LST, regional ET, build-up land and vegetation information by Landsat satellite images, this paper finds out the spatial-temporal variation of the LST and ET in study area and conducts quantitative analysis for the relationship of the above land surface parameters. The results show that the distribution of ET in Fuzhou City has obvious zonation and the LST, urban build-up land and vegetation are significant factors affecting the urban heat island and regional ET. There is a clear linear positive correlation between ET and land surface vegetation cover and a significant linear negative correlation between ET and LST as well as between ET and build-up land information.
