摘要: 以南亚热带气候的南宁市城市道路绿化为研究对象,运用群落生态学方法,选取有代表性的22条道路进行植物配置组成结构分析。结果表明:南宁市现有道路绿地主要应用的乔木树种有63种(隶属27科),灌木49种(隶属26科);出现频度最高的乔灌木分别为扁桃Amygdalus communis(63%)和黄金榕Ficus microcarpaGolden Leaves(73%);乔木与灌木的种类配比为1.3 ∶ 1;乔木的常绿、落叶树种的种类配比11 ∶ 1。垂直结构上,22条道路中有11条道路为乔灌草3层结合的立体结构,占总数的50%。目前南宁市道路绿化已形成了一定景观,但仍存在种类不够丰富,特色不够明显,景观效果较为单一等问题。应丰富植物种类,增加观花观果植物,提高乡土树种利用比例,优化植物景观配置等。图2表2参14Abstract: To provide some practical methods and strategies concerning street planting for garden-city development,a street-planting survey in Nanning,a city with a northern-subtropical climate,was conducted using a community ecology approach to determine the plant community structure along 22 major streets. Results showed a total of 63 tree species from 27 families and 49 shrub species from 26 families. The tree species with the greatest number was Amygdalus communis(63%),and the shrub species with the most individuals was Ficus microcarpaGolden Leaves(73%). The ratio of tree species to shrub species was 1.3∶1,and the ratio of evergreen to deciduous tree species was 11∶1. The three-dimensional structure of tree,shrub,and herb was found on 11 (50%)of the streets. [Ch,2 fig. 2 tab. 14 ref.]
