THE APPLICATION OF GIS TO THE ANALYSIS OF THERMAL RESOURCES

Based on logistic analysis and methology of GIS (Geographic Information System),the thermal resources in Liaoning Province were calculated and distributed into netgrid of 500 meters.The spacial distribution modezs were established seperately.GIS technology can precisely present the information of thermal resource on computer and therefore complete the inventory rapidly and exactly. In this paper,the distribution characters of main thermal resourcee in Liaoning were analysized focused on the change of thermal resource in the 1990's and also provided the scientific basis for reasouable utilizatior of thermal resources.
