南宁市人民公园彩叶植物资源调查与分析

Investigation and Analysis of Color-leafed Plant Resources in Nanning People's Park

以南宁市人民公园彩叶植物为研究对象,采用抽样调查、查阅文献、咨询专家的方法和数量生态学中的频度统计法,对彩叶植物的种类、观赏色彩、生长状态、应用类型等情况进行分析。结果表明:公园彩叶植物75种,隶属39科61属,草本彩叶植物所占比例最大;配置方式主要有丛植、群植、列植、基础种植及图案种植、立体绿化、植物与园林其他要素的配置,不同功能分区的绿地植物配置和种类应用有一定差异;公园彩叶植物的应用频度普遍偏低,种类相对分散,说明多样性丰富,与不同功能分区绿地种类应用有一定差异。建议适当增加本地彩叶乔木和灌木,以凸显色彩的层次感;加强本地新叶有色类植物种类的应用。

Taking color-leafed plants in Nanning People′s Park as the research object,this paper analyzed the species,ornamental color,growth state and application types of color-leafed plants by means of sampling survey,literature review,expert consultation and frequency statistics method in quantitative ecology.The results showed that there were 75 species of color-leaved plants,belonging to 39 families and 61 genera in the park.Herbaceous color-leaved plants accounted for the largest proportion.The allocation modes mainly include cluster planting,group planting,row planting,base planting and pattern planting,three-dimensional greening,and the allocation of plants and other garden elements.There are certain differences in the allocation and species application of green space plants in different functional areas.The application frequency of color-leaved plants in parks is generally low,and the species are relatively scattered,indicating rich diversity,which is different from the application of green space species in different functional zones.It is recommended to add local color-leaf trees and shrubs to highlight the color layers,and enhance the use of local new leaf coloured plant species.
