摘要
通过对连平县河头县级自然保护区植被的实地考察、走访和标本采集鉴定,对本区的植物种类组成、分布区类型和区系特征进行了统计分析,结果表明:河头县级自然保护区维管植物190科662属1143种(包括栽培植物40种),其中蕨类植物37科73属107种,裸子植物6科7属9种,被子植物147科582属1027种。保护区种子植物科的地理成分中,在去除世界广布科后,以热带性分布的81科(占72.32%)为最明显,温带性分布科有28科,占25.00%。保护区植物科的植物区系表现出较强的热带性兼有一定的温带性。保护区的植被型组有3个(针叶林、阔叶林、栽培植被),植被型有4个,有9个群系。地带性植被是中亚热带季风常绿阔叶林,在保护区植被中占优势地位。
This paper makes a statistical analysis of the plant species composition, distribution area types and flora characteristics in this area through field visits, visits and specimen collection and identification of vegetation in the Hetou County Nature Reserve in Lianping County. The results showed that: 190 families, 662 genera and 1143 species of vascular plants(including 40 species of cultivated plants) in the Hetou Nature Reserve, including 37 families, 73 genera and 107 species of ferns, 6 families, 7 genera and 9 species of gymnosperms, and 147 families,582 genera and 1027 species. Among the geographical components of the seed plant family of the protected area, after the removal of the worldwide distribution family, the 81 families(72.32 %) with tropical distribution are the most obvious, and the temperate distribution family has 28 families, accounting for 25%. The flora of the family in the protected area showed strong tropical and temperate characteristics. There are 3 vegetative groups(coniferous forests, broad-leaved forests, cultivated vegetation), 4 vegetative types, and 9 groups in the protected area. The zonal vegetation is a mid-subtropical monsoon evergreen broad-leaved forest, which predominates in the vegetation of the reserve.
