Change Analysis of Land Use and Land Surface Thermal Environment

摘要

The Pearl River Deka has experienced a rapid land use change over the past two decades due to its dramatic economic growth. This paper anglicized the land use change and the surface temperature in the region integrating the remote sensing data and geographic information system (GIS). Multitemporal Landsat Thematic Mapper images were used to carry out land use and the land surface temperature (LST). The remote sensing image classification with the object-based method implied this way of land use mapping is effective to comprehend information on the nature, rate and location of land use change. Results revealed a notable increase of built-up area and the decrease of vegetated land use types between 1990 and 2000. The spatial pattern of LST was correlated with the pattern of land use. Built-up land development was uneven in different parts of the study region. and its expansion influent the transfer of the heat distribution.
