南京市主要广场的木本植物群落物种组成分析

研究调查了江苏省南京市主城区具有代表性的24个星级广场乔、灌木的物种组成，观赏习性（观花、观果、观叶、观形），应用频率及重要值等。研究结果表明：南京城市广场木本植物种类较丰富，共有53科91属124种（包括种以下单位），其中：乔木类62种，灌木类52种，藤本类6种，竹类4种，但乡土树种应用偏少，骨干树种较单调，观赏植物配植不尽如人意。建议增加观花观果植物、芳香植物及南京市市树市花在南京城市广场的应用。表4参11

Species composition of woody plant communities in urban plazas of Nanjing

Research in species composition and community structure in urban plazas is valuable for optimizing plant landscapes for plazas,improving the ecological security of artificial communities through increasing diversity,and constructing systems of urban,green land.Species composition,ornamental value(of flowers,fruits,leaves,and bodies),and ecological characteristics(frequency and importance value) of woody plants from 24 chief urban plazas in the main districts of Nanjing were determined by field survey.Results showed 1) there were 124 woody plant species,belonging to 91 genera of 53 families.Among these,62 were tree species,52 were shrubs,6 were climbers,and 4 were bamboos.2) abundant woody plant species,but application of native species was inadequate,primary species were repetitive.3) planting and arrangement of ornamental plants were not satisfactory.More application of flowering plants,ornamental fruit plants,aromatic plants,as well as the City Tree(Cedrus deodara) and City Flower(Prunus mume) were advocated.
