中南大学校园维管植物构成与分析

Vascular plants on campus of Central South University

为了了解中南大学的植物种类构成和分布,采用实地走访的方法,对中南大学6个校区的维管植物进行了调查和鉴定.结果表明:中南大学共有维管植物110科276属377种,包括园林种198种,常见室内花卉与蔬果47种,野生种132种;园林种的生活型多数为常绿或者落叶的木本植物,而野生种的生活型则多为多年生和1~2年生的草本植物;园林种中有100种为乡土种,占50.51%,野生种中有20种为外来种,占15.15%;6个校区的维管植物种类和组成不同,新校区特色植物最多.总体而言,中南大学植物种类比较丰富,尤其乡土种的应用比较广泛.建议加强入侵种的管理和藤本或攀援植物的应用,增加校园植物物种和景观多样性.

To reveal the plant species composition and distribution of Central South University,the campus vascular plant resources were investigated and identified in the six campuses by field visits.There are 377 vascular plants belonging to 276 genera in 110 families.Among them,there are 198 cultivated plants,47 domesticated plants and 132 wild plants.The life type of cultivated plants is mainly evergreen or deciduous woody plants,while the life type of wild plants is mainly perennial,annual and biennial herbs.There are 100 indigenous species,accounting for 50.51%of the cultivated plants,while there are 20 exotic plants,accounting for 15.15%of the wild plants.The types and compositions of vascular plants in six campuses are different and the new campus has the most characteristic plants.In general,Central South University is rich in plant resources and indigenous plants are popular.The management of invasive alien plants should be strengthened and more rattan plants or climber materials can be applicated,so as to increase the diversity of plant species and landscape on campus.
