湖北黄石国家矿山公园种子植物区系研究

Study on Flora of Spermatophyte in Huangshi National Mine Park,Huibei,China

在野外调查和资料整理的基础上,对黄石国家矿山公园自然植物区系组成和分布区类型进行了研究。该地区共有种子植物129种,隶属于51科、96属;科的分布类型以世界分布和泛热带分布为主;属的分布以泛热带和北温带分布属为主,温带成分和热带成分比例相当,反映出该区是亚热带和温带植物区系的交汇地区。该区植物种类较为贫乏,草本植物类型占明显优势,充分体现出该区植被的次生性特点。

Based on the field investigation,the flora of spermatophyte in Huangshi National Mine Park was analyzed.There were 51 families,96 genera,and 129 species of seed plants.The top families distribution types were cosmopolitan and pantropic ones,the main genera distribution were pantropical and North temperate ones,and the proportion of the tropic and temperature ones were close.The results showed that the region was a intersection of subtropical and temperated flora.In this area,the species were lack and herbaceous had a distinct advantage,which showed a secondary characteristic of the vegetation.
