摘要
通过实地调查,对广州长洲岛的植物多样性进行研究。据统计,该岛野生维管束植物共有487种,隶属于127科358属,植被主要为次生性常绿阔叶林及人工植被(果园)。对岛上野生植物的多样性和区系地理进行分析,结果表明:该岛物种集中于少数科内,科属的优势现象明显。在植物区系上,该区具有较强的热带性,但温带成分也有一定程度的入侵。最后对岛上植物多样性的保护提出建议。
Based on the field survey,the plant diversity of Changzhou Island,Guangzhou was studied.There are a total of 487 vascular plant species belonging to 358 genera,127 families on the island,and the dominating vegetation are secondary evergreen broad-leaved forest and artificial vegetation.The diversity and geographical area of the wild plant on Changzhou Island were analyzed,the results indicated that few families are the dominant components of flora,and tropical elements predominate in the flora but there is a degree influence of temperate elements.Finally,suggestions for the protection of plant diversity were proposed.
