Abstract: The key meteorological factors and forest fire conditions of Qiannan prefecture in spring forest fire control season during 2001 to 2008 were analyzed by using Kring mapping and classic statistics methods.The results showed that: the spatial distributions of precipitation,evaporation and the maximum wind speed of Qiannan prefecture in spring forest firecontrol season were heterogeneous,and that of the maximum air temperature and the minimum air relativity humidity were more homogeneous.Horizontal and vertical zones were found in spatial distributions,and the variations with time were significant.Forest fire frequency and area of Qiannan prefecture were showed as an increasing trend in spring forest fire control season during 2001 to 2008.If the Qiannan prefecture was divided two parts by the line of Duyun,Pingtang and Luodian,then the forest fire frequency and area of the southeast of the line were more than those of the northwest.

Key words: Qiannan prefecture, Spring forest fire control season, meteorological factors, forest fire, spatial and temporal dynamic
