郑州市高校校园木本植物区系调查与分析

Flora Investigation and Analysis of Woody Plants in the Campus of Zhengzhou City

摘要:

摘要：为丰富城市植物区系内容，选取郑州市9所典型高校，在全面实地调查基础上，统计分析了郑州市高校校园木本植物区系的组成成分、分布区类型。结果表明：共有木本植物60科115属191种；在科属多样性上以寡种科属植物和单种科属植物居多，蔷薇科植物种数最多，大属植物较少；在属的分布区类型上，以北温带分布和东亚分布较为突出。郑州市高校校园木本植物区系复杂，地理成分多样，但物种种类多样化上仍有待提高。

Abstract:

Abstracts:In order to enrich the content of urban flora, the composition and distribution types of the woody plant flora belonging to 9 typical universities in Zhengzhou City were investigated and analyzed on the basis of comprehensive field survey.The results showed that there were 191 woody species belonging to 115 genera and 60 families in the campus of Zhengzhou.More plants among them belong to oligo species family and genera,single species family and genera in diversity of the family and genus.Wood species of Rosaceae were the most,large genus less. Based on their geographical distribution,wood species belonging to North Temperate Zone and East Asia-Japan zone were predominant in the distribution patterns of genera.In addition,the woody plant flora in the campus of Zhengzhou is complicated in geographical element,but the diversity of the species is still to be improved.
