广州市流溪河森林公园植物区系的初步研究

A PRELIMINARY STUDY ON THE FLORA OF LIUXIHE FOREST PARK, GUANGD

摘要:

本文从植物区系地理学的角度，讨论了流溪河森林公园植物区系的基本特征、科属地理成分、与邻近植物区系的联系．以及在中国植物区系研究中的作用．本区系位于泛北极植物区、中国－日本森林植物亚区、华南地区。初步分析结果表明，该区系的热带、亚热带成分占有明显的优势，并具有向古热带印度－马来西亚植物区系过渡的特点．本区系和鼎湖山、黑石顶区系联系密切．具有相似的典型南亚热带区系成分．研究流溪河植物区系的组成和特点．对于进一步研究华夏植物区系以及我国植物区系和其它植物区系的联系．均有一定的意义。

Abstract:

The floristic composition in Liuxihe Forest Park with an area of more than 140thousands mu (9 300 ha) lcoated 100 km on the north from Guangzhou wasanalysed, and its relation with other floras in Guangdong Province was compared.The flora of Liuxihe Forest Park is considered as a part of South China district belonging to the Sino-Japan Forest subregion of Panarctic region. The study indicates that the floristic composition of Liuxihe Forest Park is dominated by tropical and subtropical elements with the characters of transition from Panarctic Flora to Paleotlopic Indo-Malesian Flora. This flora is in close relation with Dinghushan and Heishiding floras having similar typical composition of south subtropical flora in Asia.
