山西大同大学校园植物区系特征分析

在对山西大同大学校园植物进行全面调查的基础上，进行了校园植物区系分析，结果表明：山西大同大学校园共有植物82种，隶属35科62属。大同大学校园植物属的区系成分类型多样，具有明显的温带色彩，温带成分占绝对优势，达48属，占总属数的81.35％（其中北温带成分30属，占总属数的50.85％），在校园植物区系中具有重要的地位。在校园植物种的区系成分中，中国特有种占优势，达25种，占总数的30.87％。从整体上来看，校园植物区系成分多样性较低，植物种类少，组成结构简单。建议加大校园植物的引种，提高校园植物多样性。

Analysis on the Floristic Characteristic of Campus Plants in Shanxi Datong University

On the basis of thorough survey on the diversity of plant in Shanxi Datong University, floristic characteristic was analyzed in this paper. The investigation results show that there are 82 types of plants identified in Shanxi Datong University, belonging to 35 families and 62 genera. There were some typical characteristics of warm-temperate. Among them, temperate distribution elements had 48 genera and accounting for 81.35%in the total genera （excluding cosmopolitan） in the flora of campus plants, which made significant dominant for the floristic elements. Moreover, among floristic elements of species,the endemics to China had 25 species accounting for 30.87%in the total species,making evidently dominant. It is found that the flora diversity of the plant on campus is lower as a whole and the structure needs to be enhanced by more diversity.
