| 摘 要： | 利用1995年10月~次年5月至2012年10~次年5月玉树地区草原火灾资料和气象观测资料,分析了玉树地区草原火灾的时空分布特征以及降水、风、气温、地温、相对湿度等气象要素的变化对玉树地区草原火灾发生的直接或间接影响,并利用经验公式对玉树地区的草原火险指数进行划分5个气象等级,分别为不易引燃、难燃、可燃、易燃和极易燃,对开展玉树地区草原火险预报服务及灾害防御有一定的使用价值。

| Abstract: | By Using the grassland fire and observed meteorological data from October 1995 to May 2012,to analyze the spatial and temporal features of grassland fire and the impact of rainfall、wind、temperature、ground temperature and relative humidity. By using the empirical formula,the fire danger index is divided into5 grades,the grades are as follows： not easy to ignite、nonflammable、combustible、inflammable and highly flammable. It is quite useful in forecasting and disaster prevention of grassland fire. |
