In this study, Yunnan Province was chosen as the study area.Five meteorological factors, namely, precipitation, temperature, wind speed, evaporation and relative humidity, as well as the grid of tree species and the land use distribution in Yunnan Province were taken as fire risk factors during the forest fi re prevention period.By standardization and offering different weights to each factor, area division of meteorological forest fire risk at different rankings in Yunnan Province was made with the analysis and calculation functions of ARCGIS, which was verified by historical record of forest fires.According to the result, the development trend of meteorological forest fire risk area division is consistent with the real situation in Yunnan from December to May.This result accurately reflects the regular meteorological forest fire levels in different months during the forest fire prevention period by comparing with the history of forest fire records, which shows its practical value.
