对毛红椿天然林群落结构和物种多样性进行调查分析,旨在为保护毛红椿天然林和推广人工造林提供理论依据.研究结果表明:毛红椿天然林群落的物种多样性丰富,与毛红椿混生的植物种类有56科85属122种,而且层次性较强,分为乔木层、灌木层、藤本层和草本层4层.4个毛红椿天然林群落乔木层中,江西九连山群落Simpson多样性指数最高,浙江龙泉昌岗毛红椿群落为最低;浙江龙泉昌岗群落的均匀度指数最高,浙江九龙山群落为最低.浙江龙泉昌岗、江西九连山和江西官山群落中毛红椿重要值为最大,浙江九龙山群落中拟赤杨的重要值为最大,毛红椿列第二.针对毛红椿天然林群落现状,为加强对其保护,应积极开展毛红椿遗传资源收集、保存和培育.

The community structure and species diversity of Toona ciliata vat.pubescens natural forest were investigated.The results showed that there were abundant species diversity in T.ciliata var.pubescens community and mixed plant species belonged to 56 families,85 genera,122 species.The layers of arbors,shrubs,liane,and herbages could be distinguished clearly.The community of Jiulian Mountain Nature Reserve in Jiangxi Province had the highest diversity indices of tree layer in four T.ciliata var.pubesces forest communities,the least was community in Changgang,Longquan of Zhejiang Province.The community of Changgang had the highest index evenness,the least was in Jiulong Mountain of Zhejiang Province.The importance value of T.ciliata var.pubescens was the highest in Changgang,Jiulian Mountain and Guanshan Mountain,while the importance value of Alniphyllum fortunei was the highest in Jiulong Mountain of Jiangxi Province.Therefore,it was suggested that the conservation of T.ciliata vat.pubescens natural forest should be strengthened and attention should be paid to collect and protect genetic resources and cultivate plantation.
