摘 要:该研究采用群落典型取样的方法,进行长白山自然保护区北坡4种天然林群落的物种多样性分析。结果表明:在4种天然林群落的乔木层中,岳桦的重要值最高,为85.60%,其次是蒙古栎,为70.83%,臭冷杉为44.26%,红松的重要值最小,为38.61%;群落多样性指数结果表明,红松群落的草本层为最大,最小为岳桦群落的乔木层。红松阔叶林群落已经处于演替的顶级阶段,群落非常稳定;臭冷杉群落物种丰富,群落相对复杂,森林结构比较稳定;岳桦群落海拔较高,气温低,风力大,应加强保护;蒙古栎群落自然更新能力较强,应辅以人工管理。The typical natural forest community species diversity of Changbai mountain nature reserve was analyzed with community typical sampling method.The results showed that among the tree layers of the four natural forest communities,the maximum important value of Erman's birch 85.60 percent was the highest,followed by Mongolian oak with 70.83 percent,Sorrel fir with 44.26 percent,Korean pine with 38.61 percent.Community diversity index for the herbaceous layer of the Korean pine community was the largest,and the tree layer of the Erman's birch community was the smallest.The community of Korean pine was at the top stage of succession,its the community was quite stable.Spruce community was relatively complex but rich in species,and its forest structure was relatively stable.The community of Yuehua was at the high altitude region with low temperature and heavy wind,which needs to be strengthened protection.Quercus Mongolica community showed a strong natural regeneration ability,which should be assisted by artificial management.
