| 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。

| Abstract: | Forest fire and meteorological data during 1972-2005 in Tahe county were collected.Number of occurrence,meteorological 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 for... |
