高职校园种子植物区系特征研究

A floristic study of seed plants in the higher vocational campus

在对高职校园植物种类调查的基础上,对其科、属的分布区类型进行统计分析,得出区系特征如下:该校园植物种类较为丰富,共有种子植物223种,隶属于90科177属;优势科属不明显;属种系数较高(79.37%),这与生境单一、人工栽培物种多有关;分布区类型多样,地理成分较为复杂,温带性质明显,热带成分丰富,表现出明显的过渡性。

Based on the investigation of the seed plants in the higher vocational campus, areal-types of families, generas and species were analyzed. The floristic components were complex and taxa were abundant. There were 223 species of seed plants, which belonged to 177 genera and 90 families. Dominant families and genus were not obvious. High genera coefficient （79.37%） was closely related to both the simple environment and the diversity of the source of cultivated plants. The types of distribution were various and geographical elements were complex; The flora showed a transition which owned an obvious temperate zone character and abundant tropic zone taxa at the same time.
