Analysis of the impact of Land use/Land cover change on Land Surface Temperature with Remote Sensing

摘要

Nowadays, more than 40% of the population lives in Chinese cities. The rapid urbanization process brought about many ecoenvironmental problems, such as the drastic change of land use and development of urban heat island. Three Landsat TM and ETM+ images data of Beijing acquired on April 9, 1995 and April 30, 2000 were selected to this research. The land surface temperature (LST) and land use and land cover (LULC) classes were retrieved and extracted. The temperature-vegetation index (TVX) space was constructed to investigate the influence of land changes over LST. The result showed that the land use change was an important driver for LST increase, the temporal trajectory of pixels in the TVX space migrated from the dense-vegetationlow temperature condition to the sparse vegetation-high temperature condition.
