摘　　要：应用景观生态学基本理论、选用基本方法对大兴安岭(黑龙江省管辖范围内)森林植被的变化进行了分析,其结果由于林木采伐等人为活动对其干扰,使得森林景观发生了根本性的变化,导致原始林斑块数量增多,森林在景观中的面积减少,森林的斑块形状趋于不规则,森林内部生境的面积减少。而森林的斑块被隔离,导致生物多样性下降,景观破碎程度逐期加大。The analysis of forest vegetation change in Da Xing An Mountain based on fundamental principles of landscape ecology theories.The research indicated that forest harvest cutting and other human activities resulted in the fundamental change of landscape ecology and increased the number of virgin forest patches,decreased the area of forest in landscape,the forest patches had the tendency to be irregular,and the area of habitat in forest was reduced.For the isolation of forest patches,the biodiversity had declined and increased the extent of landscape fragmentation gradually.
