前言大兴安岭北部特大森林火灾发生于1987年5月6日下午,熄灭于6月2日。初步调查火场总面积为125,5万公顷,其中林地过火面积约88万公顷,烧死林木约2,800万立方米(不包括幼林)。贮大场原木、房屋机具、车辆、通信器材、工具以及扑火费用等直接损失竟达五亿多元。被烧林木亟待采伐运出,长期放置山中,很快腐朽,而且易染病虫害,也成为第二次火灾的隐患。现在植被基本恢复,火烧迹地在2—3年内即出现桦树幼林或落叶松桦树混交林。对生态平衡影响不大。
Foreword The forest fire in the northern Great Xing’an Mountains occurred on the afternoon of May 6, 1987, and was extinguished on June 2. The total area of the fire scene under investigation was 1.255 million hectares, of which about 0.88 million hectares were covered by woodland and about 28 million cubic meters of forest was burned (excluding young forest). Storage of logs, housing equipment, vehicles, communications equipment, tools and fire fighting expenses, and other direct losses as much as 500 million yuan. Burned trees need to be harvested for export, long-term placement in the mountains, decadent soon, and easy to pests and diseases, but also become the second fire hazard. Vegetation is now basically restored, burned to appear in 2-3 years birch young forest or larch birch mixed forest. Little effect on ecological balance.
