摘要
通过对石家庄市园林植物组成及区系的初步调查发现,共有种子植物272种,隶属于63科132属,园林植物区系分布类型多样,以温带成分占优势。石家庄市园林植物区系中,中国特有成分有5种,单种属和寡种属占较大比例。利用瑙基耶尔生活型谱,对石家庄市园林植物分析发现,高位芽植物属种数占总属种数的82.58%,87.50%,居主导地位。
Preliminary survey on the composition and feature of spermatophyte genera in Shi-jiazhuang gardens and parks reveals that there exist 272 species of seed plant belonging to 63 families and 132 genera, with a diversity in flora distribution pattern and predomination of temperature plants. The Shijiazhuang landscape plant flora contains 5 Chinese endemic gene- ra dominated by one-seeded and depauperate genera. The life form analysis of Shijiazhuang landscape plants by Raunkiaer system of classification shows that the dominant genus and specieces of phanerophytes account for 82.58% and 87.50 % of the total genus and specieees, respectively.
