| 摘 要： | 森林火灾作为一种自然灾害,其发生原因不仅来自于自然因素,从众多的火灾调查中发现,更多地来自于人类活动因素,其发生的时空分布特点和规律,受自然和人类活动共同影响.对2003-2008年春、冬季(11月-次年4月)河南省森林防火期内遥感监测并已查明的森林火灾进行统计分析,结果发现:河南省森林火灾近年来有逐年增多的趋势;冬、春之交的3月为森林火灾的高发月份;从火灾的日变化规律来看,12-15时为一天中森林火灾的高发时段;从火灾发生的空间分布来看,伏牛山南麓发生森林火灾的频率较高.

| Abstract: | As a natural disaster,the forest fires not only come from natural factors,but also come from human activities from a large number of fire investigation.Spatial and temporal distribution of their occurrence characteristics and laws are affected by the natural and human activities common.The statistical analysis of the remote monitoring of forest fires that been identified in Henan province of the spring and winter 2003-2008,shows that the forest fires of Henan province in recent years are increasing year by ... |
