点击: ,时间:2019-07-16 08:53

核心提示:1987年是我国北方气候异常干旱的一年,东北林区已经连续3年没有下过大面积的透雨,而1986年冬季的雪又下得较往年稀少,这就使1987年的春季变得更加干燥。而几个民工在野外施工时不慎落下的火星,竟酿成了我国历史记载上最大的一次森林大火,这就是震惊中外的“5·6”大兴安岭火灾。? ? ? ??inkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif; letter-spacing: 0.544px;">1987年是我国北方气候异常干旱的一年,东北林区已经连续3年没有下过大面积的透雨,而1986年冬季的雪又下得较往年稀少,这就使1987年的春季变得更加干燥。而几个民工在野外施工时不慎落下的火星,竟酿成了我国历史记载上最大的一次森林大火,这就是震惊中外的“5·6”大兴安岭火灾。
