云南昆明四所高校校园绿地植物组成及特征分析

摘要

Four universities in Kunming gained‘National Green Model Unit’ were selected as study object in order to learn community flora composition, distribution and use of native plant species on campus by using typical sampling method. The results showed that studied campus were rich in plant species. There are 281 species of vascular plants, belonging to 97 families, 172 genera, which can represent the composition of the zonal vegetation characteristics. Plant geographical elements have the nature of the transition from temperate, subtropical to tropical zone. Through the study, we found it was urgent to accelerate the use of native plants.%以昆明市获全国绿化模范单位的四所高校校园绿地内稳定的植物群落为研究对象，采用典型抽样方法分析植物群落区系的组成成分、分布区类型以及植物的乡土性。结果表明，四所高校校园绿地植物群落物种丰富，有97科172属，共计281种维管束植物；植物地理成分有从温带、亚热带向热带过渡，能代表地带性植被的组成特征。调查表明云南的乡土植物有待进一步开发应用。
