滇中昆明地区森林火灾的火环境研究
A Study on the Fire Environment of Forest Fire in Kunming Area
摘要
Abstract
By using the methods listed below,the forest fire environment in Kunming area,middle⁃Yunnan Province was studied:1.Analyzing and contrasting the average meteorological data of each month from 1980—2009,which were divided into three sections every ten years;2.arranging and studying the information gathered from forest fires occurred recently in those areas;3.then classifying the local forest fuel types combined with the characteristics of basic topography and terrains.The results were as follows.Firstly,the fire environment tended to be advantageous to the forest fires with the maximum month average temperature increasing and the relative humidity decreasing while the month average rainfall of March and April stayed the lowest during the 30 years, which was below 30 mm.And the arid lasted from 2009 to 2013 significantly influenced the occurrence of the forest fires.Secondly,the complicated terrains and topography,especially the steep slopes and cliffs,benefited the forest fire,too.They helped the forest fire to ignite more rapidly,spread faster and grow bigger.The last fac⁃tor was the forest fuels,whose loads were very heavy. Among them,the main conifer species were Pinus yun⁃nanensis and Pinus armandii,which were very combustible during the constant arid periods.关键词
