摘　　要：为了给生态型校园道路绿地建设提供参考,利用物种丰富度指数、多样性指数及频度作为道路绿地植物群落测度指标,结合群落生态学方法,对广西柳州市3所高校校园道路绿地群落结构进行分析。结果表明:广西生态工程职业技术学院道路绿化树种有44种,隶属32科41属,其中,常绿乔木占86.2%,落叶乔木占13.8%,丰富度指数顺序为乔木层>灌木层>地被层,多样性指数顺序为乔木层>地被层>灌木层;广西工学院道路绿化树种有28种,隶属23科26属,其中,常绿乔木占73.7%,落叶乔木占26.3%,丰富度、多样性指数顺序均为乔木层>地被层>灌木层;柳州师专道路绿化树种有22种,隶属18科2属,其中,常绿乔木占9.7%,落叶乔木占8.3%,丰富度指数顺序为乔木层>灌木层>地被层,多样性指数顺序为灌木层>乔木层>地被层。结论:适当增加落叶乔木树种的应用,优化乔灌合理比例,丰富灌木、地被层植物多样性,是提高校园道路绿地植物群落季相变化、层次感、稳定性和生态性的关键。Using community ecology approach, based on the research of the species richness index, diversity index and equency of plant communities measure index in road green space, the author analyzed the plant community structure on road green space of three ecology campus to provide a reference for construction of road greenbelt of ecology campus. The results showed that on the campus green space of Guangxi Eco-Engineering Vocational Technical College, there were 44 species of green plants belonging to 32 families, 41 genera. And the ratio of evergreen tree species was 86.2%, deciduous tree species was 13. 8% ,the order of richness index was tree layer〉shrub layer〉ground layer, the order of diversity index was tree layer 〉 ground layer 〉 shrub layer. On the campus green space of Guangxi University of Technology, there were 28 species of green plants belonging to 23 families, 26 genera, and the ratio of evergreen tree species was 73. 7%, deciduous tree species was 26. 3%, the order of richness index and diversity index were tree layer 〉 ground layer〉shrub layer. On the campus green space of Liuzhou Teachers College, there were 22 species of green plants belonging to 18 families, 21 genera, and the ratio of evergreen tree species was 91.7%, deciduous tree species was 8.3%,the order of richness index was tree layer〉shrub layer〉ground layer, the order of diversity index is shrub layer〉tree layer〉ground layer. Conclusion： to increase the application of deciduous tree species, optimize the bushes and trees reasonable proportion, enrich species diversity of shrubs and ground layer were suggested to stress community seasonal change and improve layering, stability and ecology of plant communities of campus road greenbelt.
