11年前的1987年5月,大兴安岭北部发生了一场特大森林火灾,林火持续一个月,火区面积万余平方公里,其火势之大,燃烧时间之久,实属罕见。但人们大多不了解,卫星遥感对这场森林火灾的发现和监测所立下的汗马功劳。 Eleven years ago, in May 1987, an extraordinarily large forest fire broke out in northern Daxinganling. The forest fire lasted for a month and the area of ​​fire area was over 10,000 square kilometers. It is rare for it to have a long fire and a long burning time. However, most people do not understand the contribution made by satellite remote sensing to the discovery and monitoring of the forest fire.
