摘要
黑龙江省大兴安岭北部的塔河、阿木尔、图强和西林吉4个林业局地处北纬52°30′—54°51′,东经121°51′—125°5′之间,属大兴安岭寒温带明亮针叶林区,寒温带大陆性气候。气候严寒干燥,动植物组成种类贫乏。
After a catastrophic forest fire,the ecological change of mouse populations is not significantin short time,but is more obvious than in the case of forest cutting.The quantity of Cleth-rionomys rutilus reduces significantly after the forest fire in original larch forests,whereasthe quantity of C.rufocanus increases significantly.This causes severe mouse infestations inthe burned area,hindering the artificial regeneration and afforestation.The harmed rate offorest trees by mouse is 17.41±0.25%(p>0.95).According to the investigations,mouseinfestations are resulted from the compound interactions of population quantitative variationsand food.
