摘　　要：研究以典型公园城市成都为对象,采用样线调查方法对担负不同功能的13个主要植被分布区域进行植物组成调查,分析各区域的植被区系以及区域间植物组成的相似性。结果表明:成都的各植被分布区的植物物种分布不均匀,具有自然保护区的都江堰和彭州区域植物物种丰富,分别调查到277和239种植物,且蕨类植物分布较多,而人为干扰较大的大邑区域植物物种数量最少,只调查到80种;人工干扰下区域的植物物种数量依赖于其植被功能类型;整体来看,成都的植物分布主要集中在世界分布、泛热带分布及其变型、北温带分布及其变型、东亚分布及其变型等区系;具有自然保护区的区域间,人工干扰情况相似的区域间,其植物组成的相似度较高,不同区域间的植物组成相似性与区域间的水平距离和海拔差距没有明显相关性。基于调查结果,提出成都未来公园城市建设需要加强本土植物物种数量的参与比例,同时要提升龙泉山城市森林公园的功能建设。The study adopted the line transect method to investigate plant composition of 13 main vegetation distribution areas with different functions in Chengdu,a typical park city,and analyzed vegetation flora of each area and the similarity of plant composition among areas.The results showed that the distribution of plant species was uneven in each vegetation distribution area of Chengdu:Dujiangyan and Pengzhou areas where nature reserves are located were rich in plant species,with 277 and 239 species respectively,and more ferns were found,while Dayi area had the least plant species of only 80 species due to great artificial disturbance.The number of plant species in the area under artificial disturbance depended on the type of vegetation function.On the whole,plant floras in Chengdu were mainly the global distribution type,the pantropical distribution type and its variants,the north temperate zone distribution type and its variants,and the East Asian distribution type and its variants.The plant compositions had a high similarity among areas with nature reserves,the same was ture for areas under artificial disturbance,and the similarity of plant composition among different areas had no obvious correlation with the horizontal distance and elevation difference among areas.Hence,the study suggested increasing the proportion of native plant species in the future park city construction of Chengdu,and improving the functional construction of Longquan Mountain Urban Forest Park.
