| 摘 要： | 对不同程度人为干扰条件下(地区建设)香港大屿山林木群落结构(胸围大于0.3m)进行比较研究。结果显示,随干扰强度梯度的增加林木群落的物种多样性减少,即自然生长植被中的林木群落(山坡)多样性 > 轻度人为干扰的林木群落(昂坪)多样性 > 重度人为干扰的林木群落(东涌)多样性。物种组成和优势度等群落结构因子也因人为干扰程度的不同而有所不同。人类活动有意识地给林木群落引进了外来物种成分,并由这些物种组成新的群落,这些外来树种所带来的影响应该从多方面进行考虑研究。 |

| Abstract: | Biodiversity investigation on forest community structures were conducted under different gradients of human disturbance in Lantau, Hong Kong. The results show that species diversity of forest community decreases along the disturbance gradient of different intensity, diversity of forest community of natural growing vegetation (hill) >diversity of light disturbed (Ngong Ping) > diversity of heavy disturbed (Tung Chung). The species compositions and dominance also vary with the intensity of human-induced disturbance. Exotic species are introduced into the communities purposedly by human activities, and therefore build up new community structures. The ecolgical impact of exotic species should be investigated from several respects in more details. |
| Keywords: | Lantau human disturbance community diversity exotic species |
