摘　　要：以合肥环城公园为对象,研究了环城公园生态风景林的群落结构和植物多样性特征。结果表明:研究区域共统计植物44科75属79种,其中裸子植物4科7属7种,被子植物40科68属72种;树木径阶在10 cm以下30 cm以上和高度5 m以下15 m以上的乔木数量占比较高;群落树木健康状况不佳,近一半的树木处于不健康状况;六个景区常绿落叶植物比有较大差异,常绿树种偏多;群落类型可分为7种,主要以常绿阔叶和落叶阔叶混交林为主;群落结构以乔-草、灌-草居多,复层结构较少。在此基础上,对今后环城公园生态风景林营造和树木的养护管理提出了有针对性的建议。The community structure and species diversity of the eco-landscape forest in the Round-the-city park of Hefei were studied. The results showed that there were 79 species of 44 families and 75 genera in the study area, including 7 species of4 families and 7 genera of gymnosperms, and 72 species of 40 families and 68 genera of Angiosperms. The proportion of trees with diameter of 10 cm or less and above 30 cm continued to rise, the same with trees with height of 5 m or less and above 15 m.;the community trees were in poor health, and nearly half of the trees were in an unhealthy situation; The number of evergreen plants increased, and the ratio of evergreen and deciduous plants in six scenic spots were quite different; community type could be divided into 7 types, mainly composed of evergreen broad-leaf and deciduous broad-leaved mixed forest; community structure were mainly with tree and grass, bush and grass, and complex structure are less. On this basis, the future management of eco-landscape forest construction and tree conservation in the park were put forward targeted recommendations.
