| Abstract: | In this paper, ia is introduced that principle and method of monitoring forest and grasslands fire points by AVHRR data of NOAA polar orbiting satellite (Pos). And it is provided that the temporal and spatial statistics of fire points from Dec.1990 to Oct.1992 in Gansu, and probable error reason in monitoring fire .So corresponding improvement method has been offered. |
