加拿大林火天气指标系统在吉林省的应用1）

摘要

According to the characteristics of forest fires in Jilin Province , we introduced the Canadian forest fire weather index system.By the thin plate spline interpolation method , we studied the correlation of fire weather index and forest fire , and division of forest fire danger rating with the forest fire data of 1996-2010 in Jilin Province and the meteorological data in 1996-2010.Canadian forest fire weather index system is suitable for Jilin Province , and the grading method is also appli-cable.But further examination and comparison are required to make the system for forest fire forecast in Jilin Province .%针对吉林省林火发生特点，引入加拿大林火天气指标系统，利用1996—2010年气象资料和吉林省1996—2010年森林火灾数据，采用薄板样条插值方法，研究林火天气指标与林火的相关性，并划分森林火险等级。结果表明：加拿大林火天气指标系统适用于吉林省，分级方法也比较适用。但还需要进一步检验和对比研究，以使系统能够更好地适用于吉林省的林火预报工作。
