摘要
从林火发生次数、林火面积、区域分布、时间分布、发生原因等方面对滇西保山地区近年来林火特征进行综合分析,结果表明:2006—2010年滇西保山地区共发生林火145次,林火面积达2 428.51hm2;林火面积与林火发生次数关系极为密切,且呈高度正相关,相关系数为0.88,在0.01水平上具有显著性差异;自然因素以及社会因素的复杂性,导致滇西保山林火具有不均匀性和异质性;科学掌握林火发生的年际规律、月际规律、日际规律和空间分布规律能够为保山地区森林火灾的预测、预报以及安全扑救提供依据。
Forest fire characteristics in recent years in Baosha area of western Yunnan Province were analyzed from number of fires,fire area,fire spatial,time distribution &fire causes.Result shows that:from 2006to 2010,there are 145times forest fires in this area,fire area bing 2 428.51hm2.The relation between fire number &fire area is close,and is highly correlated;the correlation coefficient is 0.88,with a significant difference at the level of 0.01. The complexity of the natural factors &the social factors led to uneven and heterogeneity of forest fire in western Yunnan Province;grasping scientifically interannual law,inter-monthly law,inter-day law &the spatial distribution of the forest fire can provide basis for forecast,prediction &security fighting in the Baoshan area.
