Study on Relationship between Land Use/Cover and Urban Heat Island Based on Landsat ETM+ Remote Sensing Data
摘要
Abstract
Landsat ETM+ image was selected to extract four indices, including SAVI (Soil Adjusted Vegetation Index), MNDWI (Modified Normalized Difference Water Index), NDBI (Normalized Difference Built -up Index) and NDBaI (Normalized Difference bareness Index). Based on these indices, land use/cover types were classified through decision tree method. After that, the radiative transfer equation algorithm was adapted to retrieve surface temperature in Fuzhou to explore the spatial distribution of urban heat island and its relationship between land use/cover types of study area. Results show that higher temperature was located with a scattered pattern, which was related to certain land use/cover type. Con-tracture land and bareness land make the main contribute to urban heat island while the water and vegetation have a good effect of cooling down the temperature. There is a big difference of surface temperature among different land use/cover types. It was found that correlations between SAVI, MNDWI, NDBal and temperature are negative, but positive correlation is shown between NDBI and temperature.关键词
