RESEARCH ON SPATIAL-TEMPORAL CHANGE OF URBAN THERMAL ENVIRONMENT BASED ON REMOTE SENSING
Appling remote sensing technology to monitor urban thermal environment change, can reveal the spatail-temporal change process and discover the important regions of urban thermodynamic field distribution. In this paper, three periods LANDSAT remote sensing image were applied to analysis the changes of urban thermal environment in Chongqing China. The results indicated the processes and trends of urban thermal environment change in Chongqing urban. The spatial-temporal changes of Chongqing urban thermal environment were obvious from 1993a to 2004a. The area of higher surface temperature regions increased from 1993a to 2001a, and decreased from 2001a to 2004a. The spatial distribution of six temperature regions changed too. Where, highest temperature regions spatial distribution in 2004a was most dispersed, in which the area of highest temperature centres was the largest, but the area of single thermal centre was the smallest. And the total of high temperature centres in 1993a was the least, but the area of single high temperature centre was largest. The locations of highest temperature centre were moving mostly. The city of Chongqing was developed continuously and rapidly from 1993a to 2004a, and the area became larger. The land surface changed company with the urban expands. Reasonable land utilities can reduce the effects of urban thermal environment, which can be caused by urban expanding. This research provides references and basis for urban sustainable development and utilization.
