摘要
文章收集了塔河1972—2005年的林火及气象资料,对塔河地区近40年林火的发生次数和气象条件进行分析,研究塔河年际气象变化与火灾次数变化的关系,结果表明:降水量越大,分布越均匀,林火越不易发生;风对林火的影响有双重性,在一定范围内,风促进林火的发生和蔓延,超出一定范围会抑制林火的发生;温度的变化与林火发生次数呈正相变化。
Forest fire and meteorological data during 1972-2005 in Tahe county were collected. Number of occurrence, meteorologieal conditions of forest fire in recent 40 years were analyzed. The relationship between inter-annual meteorological changes and fire concentration in Tahe county were studied. Result shows that the larger the precipitation are ,the evener the distribution are, and so forest fire is not likely occur;wind have duality for occurrence of forest fire. Wind can accelerate the occurrence and spread of forest fire during certain ranges, and it can inhibit occurrence of the forest fire beyond certain ranges; changes of temperature shows positive correlation with number of occurrence of forest fire.
