本文选用2001年-2010年大理州的森林火灾次数与对应的气象数据进行统计分析,通过分析大理州森林火灾的时间分布及对应的气候特征,得出了火灾次数与气温和风速呈正相关、与相对湿度呈负相关的结论。用森林火灾次数与气象因子进行相关分析,结果表明月平均最高气温、平均相对湿度和平均最大风速与月火灾次数显著相关;旬平均最高气温、平均相对湿度和平均最大风速以及前两旬的累计降水量与旬火灾次数显著相关;日最高气温、平均相对湿度、最大风速和前15日累计降水量与日火灾次数显著相关。综合分析表明气温、降水、相对湿度和风速与大理州森林火灾次数有明显的相关性,气温、风速与火灾次数呈正相关,降水、相对湿度与火灾次数呈负相关。
本文選用2001年-2010年大理州的森林火災次數與對應的氣象數據進行統計分析,通過分析大理州森林火災的時間分佈及對應的氣候特徵,得齣瞭火災次數與氣溫和風速呈正相關、與相對濕度呈負相關的結論。用森林火災次數與氣象因子進行相關分析,結果錶明月平均最高氣溫、平均相對濕度和平均最大風速與月火災次數顯著相關;旬平均最高氣溫、平均相對濕度和平均最大風速以及前兩旬的纍計降水量與旬火災次數顯著相關;日最高氣溫、平均相對濕度、最大風速和前15日纍計降水量與日火災次數顯著相關。綜閤分析錶明氣溫、降水、相對濕度和風速與大理州森林火災次數有明顯的相關性,氣溫、風速與火災次數呈正相關,降水、相對濕度與火災次數呈負相關。

The data of forest fire frequency and meteorological conditions from 2001 to 2010 in Dali Prefecture were used to analyze its forest fire time distribution and climate characteristics. The results showed that the temperature and wind speed were positively correlated with the fire frequency, and the relative humidity was negatively correlated with the fire frequency. After analysis of forest fire frequency and meteorological factors, the results showed that monthly mean maximum temperature, mean relative humidity and mean maximum wind speed were significandy correlated with monthly frequency of fires; Mean maximum temperature ,mean relative humidity,mean maximum wind speed for 10 days and the precipitation for 20 days were significantly correlated with frequency of fires for 10 days ; Daily maximum temperature, mean relative humidity, maximum wind speed and precipitation for 15 days were significantly correlated with daily frequency of fires. Comprehensive analysis showed that there was a significant correlation between temperature, precipitation, relative humidity and wind speed with forest fire frequency in Dali prefecture, the temperature and wind speed were positively correlated with fire frequency, and the precipitation and relative humidity were negatively correlated with fire frequency.
