湖南长沙高校校园绿化及植物多样性现状调查与分析

对湖南长沙9所高校校园的绿化现状和植物种类进行实地调查，并结合SBE法对校园景观质量进行评价。结果表明：①湖南高校绿化中常见的园林树木种类共有224种，其中乔木80种、灌木118种、藤本植物10种；②9所高校乔木层各物种分布较均匀，无明显的优势种，而灌木层优势度较大；③不同学校之间乔木层和灌木层的均匀度指数存在显著差异，湖南大学、中南大学等老校区的物种分布均匀度明显高于其他新建校区。SBE分析显示，9所高校的园林植物景观评价排序依次为湖南大学、中南大学、湖南商学院、湖南广播电视大学、中南大学铁道学院、中南林业科技大学、长沙理工大学、中南大学湘雅医学院、湖南中医药大学。调查发现长沙高校绿化中存在的最突出问题为植物多样性不高、不重视科学引种、种植设计不合理等，并就此提出了深化校园绿地建设的对策和建议。

Analysis of Greening and Species Diversity of Campus Communities in Changsha of Hunan Province

A survey on plant species used in campus of 9 universities in Changsha was carried out,combined with SBE method,the quality of campus landscape greening was evaluated.① There were 224 kinds of tree species,including 80 kinds of trees,118 kinds of shrubs,10 kinds of vine applied in university campus in Changsha.②Simpon index on the tree layer of nine universities showed a even distribution of the species and there are no clear dominant species,shrubs layer showed a greater dominance.③ Pielou index of tree layer and shrub layer showed a significant difference between schools,Pielou index of Hunan University,Central South University which are old campus was significantly higher than other new campus.SBE results showed that universities which have a long history have better views.The lower level of the biodiversity and unreasonable planting design were the most key problems in campus greening in Changsha,and the suggestions and countermeasures were put forward.
