摘要
利用1950~1988、2005~2015年湘西州森林火灾相关资料,1960~2015年湘西州8县(市)气象观测站温度、湿度资料,采用线性和曼-肯德尔( MK)突变检验的分析方法,对湘西州森林防火与气象条件关系进行研究。通过研究得出气象条件和森林火灾关系非常紧密,每年的春冬季节是森林火灾的高发期;确定森林火险预报模型为I=D ×4+(100-H)×0.4+T+F+r,将森林火险等级划分为五级;对湘西州森林防火预警预报系统进行研发,将森林防火气象预报预警模型与突发事件预警信息发布的业务充分融合。
Abstract
By using relevant data of forest fire from Xiangxi Meteorological Bureau during 1950-1988, 2005-2015, temperature and humidity data from 8 counties(cites) meteorological station in Xiangxi Prefecture during 1960-2015, adopting linear and MK mutation test analysis meth-od, the relationship between forest fire prevention and meteorological conditions was studied.It was found that there is a very close relationship between meteorological conditions and forest fire.High incidence of forest fires is in spring and winter.The calculation formula [I=D ×4+(100-H) ×0.4+T+F+r] for early-warning of forest fire was determined, and forest fire was divided into 5 grades.The developed early-warn-ing system for forest fire prevention in Xiangxi Prefecture fully integrates forest fire prevention meteorology early-warning model and emergency early warning information release.
