摘要
【目的】调查贵港市城市公园绿地园林植物物种资源及绿地现状,旨在为该市园林绿地建设中植物景观的营建提供科学依据和实践参考。【方法】通过对贵港市现有5处城市公园绿地园林植物物种资源开展实地调查,并查阅相关文献资料,编制《贵港市城市公园绿地园林植物名录》,对其园林植物物种资源进行统计与分析。【结果】贵港市城市公园绿地共有园林植物334种,隶属于103科249属;以豆科、桑科、棕榈科、百合科、大戟科、天南星科和桃金娘科等8科为优势科;生活型乔木∶灌木∶藤本∶草本占比为45.81∶22.46∶3.89∶27.84,木本植物与草本植物之比约为7∶3,常绿树种和落叶树种之比约为7∶3;以观花和观叶植物为多,分别占39.22%和29.94%;乡土植物243种,占72.75%,本地木本植物指数为0.75。【结论】贵港市城市公园绿地园林植物物种较丰富;以常绿树种为主,呈南亚热带植物景观,四季常青;乡土植物物种占优,地域特色鲜明;植物配置科学合理,富有文化主题寓意。针对公园绿地植物应用之不足提出以下建议:因地制宜应用藤本植物,打造立体绿化景观;丰富本地木本植物种类,科学防控外来入侵植物;加大市树市花应用力度,彰显城市魅力。
【Objective】In order to provide scientific basis and practical reference for the construction of plant landscape in the construction of green space in Guigang City,the species resources of landscape plants and the current situation of green space in the city parks were investigated.【Methods】Through a field investigation on the species resources of landscape plants in five urban public parks in Guigang,and the consultation of relevant literature,the Lists of Landscape Plants in Urban Public Parks in Guigang City was compiled to conduct statistics and analysis on the species resources of landscape plants in those parks.【Result】There are 334 species of landscape plants in urban public parks of Guigang City,which belong to 103 families and 249 genera.Eight families,including Leguminosae,Moriaceae,Palmaceae,Liliaceae,Euphorbiaceae,Araceae and Myrtaceae and other families,are the dominant families of landscape plant.The ratio of life form(arbor:bush:vine:herb)is 45.81:22.46:3.89:27.84,the ratio of woody plants and herbaceous plants is about 7:3,and the proportion of evergreen trees and deciduous trees is about 7:3.There are lots of flowering plants and foliage plants,accounting for 39.22%and 29.94%,respectively.There are 243 species of native plants,accounting for 72.75%of the total species,and the native woody plant index is 0.75.【Conclusion】There are abundant landscape plant species in urban public parks in Guigang.With evergreen trees as the main species,which shows a south subtropical plant landscape,and the trees remain green throughout the year.In urban public parks in Guigang,the native plants are dominated,showing distinct regional features.The plant configuration is scientific and reasonable with rich meaning of cultural themes.In view of the deficiency in the application of landscape plants in park green space,some suggestions are proposed as follows:applying lianas according to local conditions,creating three-dimensional green landscape,enriching native woody plant species,controlling the invasion of exotic plants scientifically and strengthening the application of city tree and city flower s to present the fascination of the city.
