Abstract: The temporal and spatial characteristics of forest fire in Sichuan are analyzed with fire information derived from forest fire remote sensing monitor data, meteorological observation data of Sichuan Meteorological Administration and cloud fraction data observed by MODIS satellite sensors. Results indicated that forest fire occurred mostly from February to April in the south of Ganzi, Liangshan and Panzhihua. These areas have the maximum daily temperature and the minimum precipitation in Sichuan Province. Less precipitation in previous winter also favors the high frequency of forest fire in these areas. The chance of forest fire is low after May when precipitation begins to increase rapidly. The areas with high forest fire frequency are also corresponding to the areas with the minimum total cloud fraction at day. Because of high diurnal range of temperature in the plateau, daily maximum temperature is a more significant indicator of the forest fire distribution compared with daily mean temperature.
