摘要
在对合肥环城公园绿地实地调查的基础上,对绿地植物群落的组成、结构、特征及类型进行研究.结果表明:合肥环城公园绿地植物群落有145种,属于64科114属.乔木层树种有62种,木犀科、豆科、杉科、木兰科和松科等为优势科,刺槐、女贞、构树、枫杨、棕榈、水杉、黄山栾和广玉兰等为优势种.少数种占有较大比例,优势种群中常绿树种占有一定比例.群落类型中,常绿落叶阔叶林和落叶阔叶林占群落总数的87.04%.乔木层、灌木层优势种中,引种栽培植物占有相当比例,与城郊次生植被以地带性树种形成的森林群落有一定区别.应以地带性树种为主体,在遵从植物生态位的基础上,合理配置灌木和宿根地被植物,逐步形成稳定的复合植物群落.
An investigation of communities from the typical sample plots was conducted on green space of Around-Hefei Park.The results revealed that 64 families, 114 genuses, 145 species were recorded in the area and 62 species in the tree layor. Oleaceae, Leguminosae, Taxodiaceae, Magnoliaceae and Pinaceae etc were dominant families. Robinia pseudoacacia, Ligustrum lucidum, Broussonetia papyifera, Pterocarya stenoptera, Trachycarpus fortunei, Metasequoia glyptostroboides , Koelreuteria bipinnata, Magnolia grandiflora, etc were dominant species.A large proportion was occupied by a small number of the dominant species and evergreen species occupied a certain percentage.The main type of phytocoenosis was evergreen and deciduous broad-leaved forest, deciduous broad-leaved forest, taking 87.04 percent in all types. A considerable proportion of the dominant species in the tree and shrub layor was occupied by cultivated plants, which was different fom the secondary vegetation in the formation of the deciduous broad-leaved forest.Thus, the native plants should be increased, shrubs and perennial ground cover plants should be applied reasonably complied with niche, and the importance of near eco-nature community were emphasized.
