②最小相对湿度能较好地反映天气的干燥情况，可以作为森林火险等级预报的主要依据之一；

The minimum relative humidity well represented the dryness of the weather and could be as one of the main indexes for the forecast of the forest fire risk degree .

这一方面是资料的原因，另一方面是多因子森林火险等级预报方法没有预报雷击火的能力。

On one hand , it is the cause of the data , on the other hand is the multiple factor forest fire forecast method not forecast Lightening Fire level of ability .

森林火险等级预报可以采取精确的数学方法与模糊的综合评判方法，而火险因子都具有模糊性，因此采用模糊方法更切合实际。

There are two methods to evaluate the forecast of forestry fire-danger scale : exact mathematic method and comprehensive fuzzy evaluation . All causes of fire-danger are fuzzy , so the latter is more practical .

如何采用遥感、地理信息系统技术等现代高新技术对森林火险等级进行预报和对森林火灾进行监测，成为当前国内外研究的热点。

It 's a study hotspot in worldwide how to using Modern high-tech information technologies , such as Remote Sensing ( RS ) and Geographic Information Systems ( GIS ), to forest fire danger rating predicting and forest fire monitoring .

这一分类结果，可以满足森林火险等级预报的需要，但对于火行为预报，还需要根据林分燃烧性、林分垂直结构及可燃物分布状态进一步分类。

The results can be used in the forest fire danger rating system , but there is a need for further classification for the fuel with the flammability , vertical structure and distribution in order to make the fire behavior prediction .
