Title: The relationship between spatial characteristics of land surface temperature and property of land surface in Beijing area
Abstract: Landsat 7 Enhanced Thematic Mapper Plus(ETM+) data on July 1,1999 are used in this paper.The land surface temperature(LST) and the types of land cover of urban and surrounding area of Beijing are retrieved by using RS and GIS technology.The urban heat island ratio index(URI) is selected as the indicator to estimate spatial characteristics of LST.Land cover,normalized difference build-up index(NDBI) and normalized difference vegetation index(NDVI) are selected as the indicators to estimate land surface.The relationship between spatial characteristics of land surface temperature and property of land surface has been analyzed.The result shows that different land cover has different effect on LST.The values of LST of water and forest land are lower than others,while those of urban and bare soil are higher than others.The scope of change of LST is related to proportion of varied land cover types,and the frequency of change of LST is related to complexity of texture of land cover.The value of LST possesses positive correlation with NDBI(r=0.648 6) and negative correlation with NDVI(r=-0.704 4).
