On the basis of the remote sensing data derived from meteorological satellite AVHRR through DVB-S,Hebi area is divided into several sub-areas for identifying fire points according to surface characteristics.By means of statistics and contrasting analysis of the satellite-monitored fire point data and actual fire point data,the refined threshold values in each sub-area at different time are determined.Then the administrative position of the fire points are precisely located by using 1∶50000 scale administrative data set.This method was utilized in the monitoring of straw stalk burning in Hebi area in 2004 and 2005 and obtained very good effect.It provided an important scientific basis for the government to keep abreast of the straw stalk burning situation in the whole city promptly and accurately,and improve the fire monitoring ability and inspecting efficiency as well.
