深圳笔架山公园的植被类型及主要植物群落分析

Vegetation Types and Plant Community Characters in Bijiashan Park in Shenzhen, Guangdong Province

深圳市笔架山公园的地带性植被为南亚热带季风常绿阔叶林,目前其现存植被主要包括人工次生林植被、园林植被和园地植被等几大类,其中人工次生林植被包括南亚热带人工常绿阔叶林、南亚热带次生常绿阔叶林、南亚热带次生常绿针叶林和南亚热带次生常绿灌木林等,并可进一步分成13个群落类型。对13个人工次生林群落的结构、物种多样性等特征进行了分析。分析表明,人工林占优势,物种多样性低,群落层次不明显,多数群落处于演替前期。

The typical zonal vegetation of Bijiashan park in Shenzhen,Guangdong Province is lower subtropical monsoon evergreen broadleaved forest. Its actual vegetation can be divided into 3 categories:artificial and secondary forest, grove vegetation and garden vegetation. Artificial and secondary forest can be further divided into Southern subtropical artificial evergreen broadleaved forest, Southern subtropical secondary evergreen broadleaved forest, Southern subtropical secondary evergreen coniferous forest and Southern subtropical secondary evergreen shrub forest, which contains 13 community types in all. In this paper,the community structures and species diversity were analyzed for the 13 artificial and secondary forest communities.The results show that the artifical forest is preponderant and community hiberarchy is not clear.Almost communities are on the front stage of succession.
