摘　　要：本文采用实地调查方法,对呼和浩特市公园绿地植物群落密度、覆盖度、乔灌草比、林层比、树种组成、植物来源、优势度指数等进行分析。结果表明:在树种组成结构方面,公园绿地内植物种类有49种,分别隶属于15科3,1属,物种比较单一,本地乡土树种运用的少,只占调查树种的40.8%;在水平结构上,群落密度比较合理,50%以上的群落覆盖度大于0.5,群落稍显杂乱;在垂直结构上,乔灌草比例为1:0.85:12.06:19.66,灌木数量较少,群落结构林层比较为0.465,在合理区域;在此基础上,对存在的问题提出了相应的建议。The plant community＇s space structures of different public parks in huhhot city were studied in this paper.The outdoor investigation method was used in this survey.Then the plant community density,coverage ratio,the arbor-shrub-grass ratio,the layer ratio,the composition of plant community,the origination of plants,and dominance index were analyzed and compared.The results showed that there were 15 families,31 genera and 49 species,tree species were seriously single.20 species were local plants,which account for 40.8%.On horizontal structure,the plant community density is reasonable,the plant community,which account higher then 50%,coverage ratio is unreasonable.On vertical structure,the arbor-shrub-grass ratio was 1：0.85：12.06：19.66,the application of bush species should be increased.The layer ratio was more reasonable.On this basis,some suggestions were proposed.
