摘要:
以宣城市城区公园内212个样地为研究对象进行植物群落结构调查与分析。结果表明,有园林植物171种,隶属于69科121属,乡土种和外来种分别占61.4%和38.6%,重要值最大的乔木是香樟(Cinnamomum camphora),灌木是杜鹃(Rhododendron simsii),分别为18.949%和10.173%。植物群落以人工类型为主,主要群落类型有6种,常绿落叶阔叶混交林的样地数比例最高,占43.4%,地带性植物类型常绿阔叶林仅占15.1%,群落相似度均在0.5以下,为中度不相似和极不相似,其中敬亭湖公园和梅溪公园之间的相似度最大,为0.409;响山公园和府山广场之间的相似度最小,仅0.047。

Abstract:
The result of the investigation and analysis of plant community structure in 212 sample spots in Xuancheng city parks shows that there are 171 species of garden plants belonging to 121 genera of 69 families, 61.4% of which are native and 38.6% exotic. Trees with largest importance value are camphor trees; shrubs are cuckoos, respectively accounting for 18.949% and 10.173%. There are 6 main types of plant communities, most of which are artificial. The number of sample spots with evergreen defoliate and broadleaved forests takes the largest percentage, accounting for 43.4%, and the evergreen broad-leaved forests of zonal plant type accounting for only about 15.1%. The similarity of plant community is under 0.5, between moderate dissimilarity is dissimilarity. Jingtinghu Park and Meixi Park has the greatest similarity. That is 0.409. And Xiangshan Park and Fushan Square have the minimum similarity, only 0.047.
