Abstract: Based on data of occurrences of the forest fire and daily meteorological data in 1991-2005 in Taizhou City of Zhejiang Province,the key meteorological factors affecting the occurrence of the forest fire were analyzed and constructed by the parallel correlation analysis with the Matlab.The results showed that the probability of the appearance number of the forest fire increased as the minimum air temperature decreased.The minimum relative humidity well represented the dryness of the weather and could be as one of the main indexes for the forecast of the forest fire risk degree.The wind velocity,precipitation and radiation were not significant to the appearance number of the forest fire and the burned area.The quite large number of the forest fire occurred under the conditions with the low wind velocity,rain and cloudy days.

Key words: Forest fire, Meteorological condition, Correlation analysis
