指出了校园作为城市园林植物的避难所，对校园植物群落进行调查研究有一定的积极意义。对广东外语外贸大学白云校区典型植物群落进行取样调查，计算了样地的物种多样性指数、均匀度指数和丰富度指数，综合分析群落类型、种类密度、冠幅等对群落景观的影响。结果表明：该校区的绿地植物群落类型以常绿乔木为主，落叶乔木次之，部分群落结构简单，植物群落种植密度过高，群落物种中外来植物的比例较大，但绿地植物与植物区系特征基本一致。相对于湖南长沙中南大学的物种多样性较高、均匀度指数略低、丰富度指数基本持平，根据以上情况提出了优化园林植物群落结构、构建多样性植物群落的措施。

Taking thetypical plant communities of Baiyun Campus ofGuangdong University of Foreign Studies (GUFS)as the research objective ,this article conducts the sampling investigationto calculate thespecies di-versity index ,evenness index and richness index ,andanalyzes the effects of community type ,species density , crown width on community landscape .The results show that :the plant community types in this campus are dominated by evergreen trees ,followed by deciduous trees ;somecommunitieshassimple plant structure ,high density of plant community ,andlarger proportion ofexotic plants ,w hile the green plants are basically the same withthe floristic characteristics .Compared with Central South University in Changsha ,Hunan Prov-ince ,Baiyun Campus ofGUFS hashigher species diversity andslightly lowerevenness index ,and keeps balan-cein richness indexbasically .According to the above -mentioned ,this articleproposes the measures to opti-mize the structure and diversityof landscape plant community .
