高黎贡山南段中山湿性常绿阔叶林群落生态特征研究

Ecological Characteristics of Mid-mountain Humid Evergreen Broad-leaved Forest in Southern Part of Mt. Gaoligong

  • 摘要: 根据7000 m2的样地调查资料,分析了高黎贡山南段中山湿性常绿阔叶林群落物种组成、群落结构和生活型谱。结果表明:(1)群落内共出现维管植物315种,隶属于88科164属,樟科、杜鹃花科、百合科、壳斗科为主要组成科,山胡椒属、荚蒾属、蓼属、山矾属为主要组成属;(2)群落分层明显,附生、半附生植物丰富,说明生境潮湿;(3)生活型谱以小、中高位芽植物为主,具有亚热带常绿阔叶林的特点。叶片以小型叶(49.84%)、单叶(81.27%)、纸质(44.13%)、非全缘叶(55.87%)、渐尖叶(59.68%)为主,且地面芽植物比例较高,1 a生植物和地下芽植物的数量较少,体现了典型的云南亚热带山地森林群落的特征。

     

    Abstract: In this paper based on the investigative data in a sample area of 7 000 m2,analysis was made of species composition, community structure and life form spectrum of the mid-mountain humid evergreen broad-leaved forest (MHEBF) in southern part of Mt. Gaoligong. The results showed that (1) there were 315 species of vascular plants, which belonged to 88 families and 164 genera. The main families were Lauraceae, Ericaceae,Liliaceae and Fagaceae. The main genera were Lindera,Viburnum,Polygonum and Symplocos. (2) The community could be divided into different levels, epiphyte species and hemiepiphyte species were rich,which indicated the moist habitat. (3) The microphanerophytes and mesophanerophytes were the dominant life form, which revealed the characteristic of subtropical evergreen broad-leaved forest. Microphyll, single leaf, papery leaf, non-entire margin leaf and acuminate leaf were dominant leaf characteristics. Temicryptophyte occupied the highest ratio, therophyte and geophyte were less, which showed the typical subtropical mountain forest community characteristics in Yunnan Province.
