百山祖冷杉森林植物群落的外貌与结构特征研究

百山祖冷杉森林植物群落的优势种群是由常绿的多脉青冈和落叶的亮叶水青冈组成,是一个比较特殊的天然的常绿与落叶阔叶混交林.构成乔木层的树种有8 ～ 9种,分为3个亚层,第1亚层高13m,由百山祖冷杉组成,第2亚层高8 ～ 12m,由多脉青冈和亮叶水青冈优势种群构成主要林冠层,第3亚层高4 ～ 8m,主要由第2亚层优势种群的幼树组成.百山祖冷杉植物群落的物种丰富度为17 ～ 19种,乔木层物种多样性指数明显高于灌木层和草本层,灌木物种主要由箬竹和百山祖玉山竹组成,草本物种主要为莎草科的苔草.

Study on Aspect and Structure Properties of Abies beshanzuensis Phyto-group

The dominant community of Abies beshanzuensis phyto-group is evergreen Cyclobalanopsis multinervis and deciduous Fagus lucicla, which is a natural broadleaf mixed forest. 8 ~ 9 species form the high layer divided into 3 sublayers, the first one composed by A. beshanzuensis with 13m high, the second one by dominant community of C. multi- nervis and Fagus lucicla with 8 ~ 12m high, the third one by young trees of the second layer with 4-8 high. The diversity of A. beshanzuensis phyto-group has 17 ~ 19 species and the diversity index of high layer is higher than shrub and field layer.
