通过飞机和地面两个途径,将化学灭火药剂喷洒到火场上,扑灭森林火灾。使用飞机喷洒,对于边缘和无道路的林区中火灾,具有显著的优越性。所以到目前为止,空中施用化学药剂的用量占绝对优势。我国自1973年开始研究森林航空化学灭火以来,先后研制成功适合于飞机喷洒的“704”和75型森林化学灭火剂,以及航空喷洒设备和技术等,使航空化学灭火工作有了很大进展。仅从1975年至今春防火期的期间内,黑龙江省嫩江和加格达奇两个主要灭火基地,飞机喷洒了近四百吨药液,它对我国护林防火工
Through the aircraft and the ground two ways, chemical fire extinguishing agents sprayed on the fire, put out the forest fire. The use of aircraft for spraying has significant advantages over fires in forested and non-road forest areas. So far, the amount of airborne chemicals has taken an absolute advantage. Since 1973, China began to study the forest aviation chemical fire extinguishing, has successfully developed “704” and 75 type of forest chemical fire extinguishing agent, as well as aviation spraying equipment and technology, which are suitable for aircraft spraying, so that the aviation chemical fire fighting work has made great progress. Only from the 1975 to the present period of the fire during the spring, Ninjiang and Jiagedaqi Heilongjiang Province, the two major fire bases, the aircraft sprayed nearly 400 tons of liquid, it is our country forest firemen
