Survey And Analysis Of Garden Vines And Their Landscape In Nanning City Park

Vines have high ornamental value,ecological value and cultural value,and they also play an irreplaceable role in the construction of three-dimensional greening in modern city.Through the methods of field investigation,comparative analysis,induction and synthesis,the garden vines in Nanning city park were investigated and analyzed.The research was carried out from four main aspects: the species of garden vines,the application forms of common garden vines,the typical application forms of garden vines,and the typical parks of garden vines application.And then the garden vines in Nanning city park were summarized and put forward the advantages,problems and optimization suggestions of the plant species and landscape construction,expecting to provide basic information and theoretical reference for the application of garden vines in Nanning,so as to provide assistance for the development of landscape construction of garden vines in Nanning.This study is the first systematic study of garden vines in Nanning city park.The main research results are as follows:(1)In terms of garden vine species: there are 59 species of garden vines in Nanning city park,belonging to 25 families and 52 genera.Among them,29 species are commonly used in Nanning city park,accounting for 49.15%.The first three garden vines with higher frequency of application are Bougainvillea glabra(21 times),Syngonium podophyllum(18 times),and Parthenocissus dalzielii(18 times).There are 26 species and 33 species of herbaceous vines and woody vines,accounting for 44.07% and 55.93%.According to their ornamental characteristics,they can be divided into 9 categories,flower viewing,leaf viewing,fruit viewing,stem viewing,root viewing,flower and leaf viewing,flower and fruit viewing,leaf and stem viewing,fruit and stem viewing.At the same time,according to the application forms,they can be divided into 8 categories,shed greening,column greening,rockery greening,wall greening,fence greening,ground greening,modeling greening and hanging greening.(2)In terms of application forms of commonly used garden vines and typical application forms of garden vines: among 29 garden vines commonly used in Nanning city park,10 garden vines can be the representative,which are Bougainvillea glabra,Parthenocissus dalzielii,Syngonium podophyllum,Pyrostegia venusta,Mansoa alliacea,Quisqualis indica,Tradescantia zebrina,Ipomoea cairica,Monstera deliciosa and Epipremnum aureum.Among them,Parthenocissus dalzielii,Monstera deliciosa and Epipremnum aureum are suitable for all the application forms they are used innowadays,and the landscape effect is better.Although there are some application forms with poor landscape effect of other garden vines,most of them have better landscape effect.At the same time,shed greening,column greening,rockery greening,wall greening,fence greening and ground greening are the typical application forms of garden vines.(3)In terms of typical parks of garden vines application: there are 6 typical parks of garden vines application,which are Qingxiushan Scenic Spot,Nanhu Park,Nanning People’s Park,Nanning Camellia Park,Xinxiu Park and Nanning Zoo,and they have the following experiences of building garden vines landscape that can be used for reference: the spatial distribution should be focused on "Centralized distribution is the main and decentralized distribution is the auxiliary",the landscape units should be highlighted the characteristics of "line shape > point shape > surface shape",the seasonal colors should be referred to as "purple,purplish red,orange yellow and yellow",and the own characteristics of garden vines application should be needed.
