冬樱花群落学特征研究

Study on Community Characteristics of Cerasus cerasoides

冬樱花群落高10～20m,总盖度70%～90%.以山茶科和樟科为优势科,红木荷和香叶树为优势树种,层间植物较丰富,以木质藤本占优势.常绿植物占绝对优势(92.6%),生活型组成以高位芽植物占显著优势(73.3%).群落的外貌是由纸质(63.8%)、全缘(65.4%)、单叶(77.9%)、尾、渐尖(52.1%)、中型叶(69.6%)为主的常绿高位芽植物所决定,具有次生南亚热带季风常绿阔叶林特点.群落乔木树种以中小径级占绝对优势,群落处于旺盛生长期.冬樱花种群能通过种子繁殖,且茎基部萌枝更新能力较强,在群落中属稳定种群,自然条件下不会在群落中衰退.

The height of Cerasus cerasoides community is from 10 to 20 m, the total coverage is 70%～90%. Theaceae and Lauraceae are the predominant families, and Schima wallichii and Lindera communis are the predominant species in this kind of C. cerasoides community. Evergreen plants hold a biggest position (92.9%) including evergreen microphanerophytes and nanopanerophytes (73.3%), simple (77.9%), chartaceous (63.8%), entire (65.4%), caudal (52.1%) mesophylls (69.6%). There are many woody lianas in the interlayer of the community, which demonstrate characteristics of the secondary monsoon evergreen broadleaf forest in the south-subtropical region of China. The DBH class distribution of the arbor tree species shows an obvious pyramid type, seedlings and young saplings account for the majority of the community showing that the community is in the vigorous growing stage.Cerasus cerasoides population usually regenerates by seedlings, and the root sprouts also show strong reproduction capacity, indicating that the Cerasus cerasoides is a stable population in the community and will not degrade under natural conditions.
