一、引言当今,在世界范围内火险等级的测定已成为越来越多的有林国家林火管理的有力工具。正因为它如此重要,所以国际上许许多多的林火研究工作者们不辞千辛万苦,从试验室到外场观测都做了大量的工作。他们通过不同的途径和方法,摸索到许多规律性的东西,获得了许多有实用价值的宝贵经验,取得了可喜的成绩。为了今后更好地开展我国的林火研究工作,特别是林火予报工作,我们有必要总结和比较一下世界各主要国家森林火险等级系统研究的看法和特点。各国有各自的长处和短处,我们应该吸取他们的精华,借鉴利用,在他们研究的基础上建立和发展具有我们中国特色的林火予报系统。这就是本文的目的。二、各国森林火险等级系统特点1、美国
I. INTRODUCTION Nowadays, the determination of the fire risk level in the world has become a powerful tool for more and more forest fire management in some countries. Just because it is so important, so many international forest fire researchers have done a great deal of hard work and have done a great deal of work from laboratory to field observation. Through various channels and methods, they have fostered many regularities and gained many valuable experiences with practical value, and achieved gratifying results. In order to carry out the study of forest fires in our country better in the future, especially for forest fire reporting, it is necessary for us to summarize and compare the views and characteristics of the study on the forest fire risk rating system in all major countries in the world. All countries have their own strengths and weaknesses. We should learn from their essence, use them for reference, and establish and develop a forest fire reporting system based on their research based on our own Chinese characteristics. This is the purpose of this article. Second, the national forest fire rating system features 1, the United States
