摘要
五大连池具有特殊的地理位置和成因,衍生了独特的生态特征,具有极高的科研价值。参照植物区系地理的理论和研究方法,在属的水平上对该区域种子植物区系特点进行了研究,结果表明:(1)五大连池植物区系组成丰富,共有种子植物99科369属869种,单种属和寡种属的比率很高,达到该区总属数的89.16%。(2)地理成分复杂,共有14个分布区类型和10个变型;温带成分占绝对优势,植物区系为温带性质。(3)区系起源古老。
Because of special geographical location and genesis, there are unique ecological characteristics and huge scientific value in Wudalianchi. According to the theory and methods in floristic, floristic analysis on spermatophyte genera in wudalianchi was studied. The analysis showed that： （1） The Wudalianchi seed floristic composition is abundant, there are 869 kinds of seed plants belonging to 369 genera and 99 families. The ratio of single-species and few species is very high, reaching 89.16% of total area. （2） The composition of floristic is complex, it contains 14 distribution type and10 variants type. The temperate elements of genera dominate obviously. （3） The origin of the flora is ancient, China unique genera is not obvious.
