The Study On Plant Landscape Of Commercial Centers In Hangzhou

The commercial center is an important part of the city and it is closely related to the daily life of human beings.The commercial center green space as an organic continuation of green space has important significance for cities,commercial centers and humans.Plant is an important landscape element in the green spaces of commercial centers,and the creation of plant landscapes is crucial.Taking into account the impact of greening rate and other factors,the study selected Hangzhou Kerry Center(7.89%),Intime in77(5.43%),The Mixc(12.70%),Southern Song Imperial Street(9.43%),Zhongda Intime City(31.56%)5 commercial centers conducted plant landscape surveys,analyzed their design characteristics,and explored the design principles,plant species and configuration patterns of plant landscapes of commercial centers in Hangzhou to achieve the goal of optimizing plant landscape design in commercial centers.The research results are as follows:(1)The commercial centers in Hangzhou have used 127 species of 63 families,104 genera and 127 species of plants.These plants specifically include 40 species of trees,51 species of shrubs and 36 species of ground cover plants.The commercial centers use fewer types of plants,accounting for only 1%of the existing vascular plants in the urban area of Hangzhou,32%lower than the applied plant species in urban parks.Among them,the commonly used plant family is Rosaceae(23.79%),the family contains 10 genera and 11 species;Gramineae(7.73%),the family contains 2 genera and 2 species;Aquifoliaceae(7.10%),the family contains 1 genera and 3 species;Platanaceae(5.06%),the genus contains 1 genera and 1 species.(2)The plant specifications used of the commercial centers in Hangzhou are relatively small.The arbor specifications are mainly concentrated at 5-10m high,3-5m crown width(53.81%),and shrub specifications are mainly concentrated at 0.25-1m high(72.43%).Hangzhou Commercial Center used 35.6%of evergreen trees and 95%of evergreen shrubs for plant configuration.In terms of seasonal performance,spring landscape(46.98%)and autumn landscape(36.52%)were dominant,and summer landscape(16.18%)and the winter landscape(0.33%)performed less.(3)The green space types of the commercial centers in Hangzhou are square green space(78.91%),sunken green space(2.82%)and roof garden(18.27%).As the technology of garden construction matures,the commercial center green space gradually changes from square to roof.It can be predicted that after 10 years,the commercial center green space will be mainly composed of horizontal space green spaces such as roof gardens,and combined with vertical green space types such as vertical green space and square green land.Nowadays,107 plant species(85.04%)are used in the square green space.The arbor is planted at a density of 5 m2/plant(75%),planted with a density of 5-15 m2/plant(15%)and a density of 15 m2/plant(10%)to construct a tree-shrub-type plant community.The square green space has created a green space with an area of 30m2 or less(85%),with a green area of 30-100m2(10%)and an area of more than 100m2(5%).This design creates an open space(65%)and a private space(35%)for the user.The sunken green space uses 23 species of plants(18.11%).The trees are planted at a density of 5-15 m2/plant(85%)with a density of 5 m2/plant(15%)to construct a tree-shrub-type plant community.The overall design has been built with a green area of 30m2 or less(90%),and a green area of 30-100m2(10%).This design builds a sinking activity space that is dominated by private spaces(80%)and supplemented by open spaces(20%).The roof garden uses 51 species of plants(40.16%).The trees are planted at a density of 5 m2/plant(60%),planted with a density of 5-15 m2/plant(35%)and a density of 15 m2/plant(5%)to construct a tree-shrub-ground-type plant community.The roof garden is entirely made up of 30m2 green space(70%),with a space of 30-100m2(25%)and more than 100m2 of green space(5%).This design creates a venue for the user to focus on private space(85%)combined with open space(15%).(3)The design of plant landscape in Hangzhou commercial center should follow the principle of macroscopic unity,demand-oriented principle,the principle of landscape connection,the principle of landscape stability and the principle of landscape aesthetics.In order to improve and optimize the plant landscape of the commercial center,the design needs to consider the growth habits of different plants,select the appropriate plant species;take into account the landscape effects of multiple seasons,control the reasonable season comparison;make full use of the gray space of the site to create rich The type of green space;the use of the consumer population is preset,and the function of the plant landscape is enhanced.
