长期以来,人们在预测预报森林火险等级时,一直以天气状况为主要依据,诸如空气温度、相对湿度、降水量、风力等。可是,核工业北京地质研究院的杜乐天研究员最近却提出了一个新观点——导致区域性森林大火的一个重要因素是地球排气(地幔“呼”气)作用。因此,应该考虑监测地球的排气状况,并以此作为确定森林火险等级的一个重要依据。 For a long time, people have been mainly based on the weather conditions such as air temperature, relative humidity, precipitation, wind power and so on when predicting the level of forest fire insurance. However, Du Letian researcher at the Beijing Institute of Geology of the nuclear industry recently came up with a new idea that one of the important factors causing regional forest fires is the effect of the Earth’s exhaust (the mantle’s “breath”). Therefore, we should consider monitoring the exhaust situation of the earth as an important basis for determining the level of forest fire insurance.
