摘要
通过野外样地调查,结合文献资料和标本鉴定,对戴云山自然保护区植物区系特征进行了分析。结果表明,保护区内植物多样性丰富,共有野生种子植物1 753种,隶属于181科741属;种子植物科的组成以中科、小科为主,种数集中在中等科,优势科不是很明显;种子植物属的组成以极小属为主,种数集中在小属;种子植物科、属的地理区系成分复杂,以热带、亚热带成分占优势,兼具部分温带性质;属于中国特有种有18属20种。
Based on field investigation, literature survey and species identification, the floristic characteristics of seed plants in Daiyun Mountain Nature Reserve were studied. The results showed that the species richness was relatively high and vulnerable, and the 1 753 seed plants belonging to 741 genera and 181 families were founded in Daiyun Mountain Nature Reserve. The mid- and small- sized families were dominant for the family composition of the seed plants, the major species were grouped in the midsized families, and the dominant families were not significant. The minimal-sized genus was dominant for the genera composition of the seed plants, and the major species were grouped in the small-sized genera. The areal-types were complex, with the dominant tropical- and subtropical-nature, followed by the temperate nature. The 20 seed plants belonging to 18 genera were the Chinese endemic species.
