摘　　要：我国大兴安岭地区植被资源丰富,典型林分阔叶混交林更是在整个森林群落中占据重要地位,对其物种多样性随海拔高度和坡向变化规律的研究是一项具有重要意义的工作。以大兴安岭地区按照不同海拔高度、坡向的4个典型阔叶混交林群落作为研究对象,采用设样地,并对于样地中物种多样性进行室内实验分析的方法,结果表明:①海拔高度对于林下草本植物多样性影响显著,呈显著正相关关系(P<0.01);②林下草本植物多样性会受到坡向的影响,自阳坡至阴坡林下草本植物多样性显著上升(P<0.05);③海拔高度和坡向会通过影响林分结构,来影响林下草本植物多样性(P<0.001)。Chinese Greater Khingan Mountains region is rich in vegetation resources,and the typical forest broad-leaved mixed forest occupies an important position in the entire forest community.The study of its species diversity changes with altitude and slope is an important work.This paper selects 4 typical broad-leaved mixed forest communities in the Greater Khingan Mountains area according to different altitudes and slope directions as the research objects,set up plot and analyze the species diversity in the plots.The research results show that:①altitude has a significant impact on the understory herbaceous biodiversity,showing a significant positive correlation(P<0.01);②understory herb biodiversity will be affected by the aspect,and the understory herb biodiversity will increase significantly from sunny slope to shady slope(P<0.05);③elevation and aspect will affect the understory herbaceous biodiversity by affecting the stand structure(P<0.001).
