Study On Landscape Design Of The Plant Community In Qingdao Coastal Greenbelt

The plant is the main material which constitutes the garden landscape and an indispensable part of the garden construction.As the main part of urban Greenland system,the garden plant community with growth condition,species composition,community structure and landscape quality,decided to play the various functions of greenbelt in a large extent,which affects the quality and level of the vegetative landscape in urban Greenland.Along with the domestic coastal city paying more and more attention to the seaside landscape construction,humans' demand to the plant community landscape of coastal greenbelt is also increasing day by day.As the tourist attraction,the plant community landscape of coastal greenbelt which has the unique natural condition,directly affects the landscaping quality and level of coastal city.Therefore,according to the particularity of the soil and environment condition of coastal greenbelt,it is important to construct the scientific and reasonable plant community to protect the city diversity,create the harmonious human habitation environment and highlight the city characteristics.This study is based on the theories and methods of Landscape Architecture,Community Ecology,Forest Science,Landscape Aesthetics,and so on.Investigating and analyzing 41 relative stable plant communities in the coastal greenbelt of Qingdao by field investigating,surveying and mapping.In this paper,the characteristics of plant community landscape design of Qingdao coastal greenbelt are analyzed in detail,and the existing problems and solutions are proposed,and the features of the community view of the landscape are summarized.The paper summarizes the methods and principles of landscape design of coastal plant community,and aiming at the partial problems of Qingdao coastal greenbelt to carry out the detailed optimum design of the plant community which is poor in the landscape effect of the former article,provides reference for further development of the landscape design of Qingdao coastal greenbelt plant community,and also provides reference for other coastal cities in north China.The results show that:(1)In the case of 41 in this survey,a total of 95 species of plants,belonging to the 43 family 74 genus,in which Rosaceae 8 genus 11 species,Oleaceae 5 genus 8 species,Pinaceae 3 genus 6 species,the average trees and shrubs ratio(type ratio)is about 1:1.3,the proportion of evergreen and deciduous plant species is about 2:3;The important value of species in plant community is Pinus thunbergii,Celtis sinensis,Cedrus deodara,Sabina chinensis,Fraxinus chinensis and so on;the important value of small trees and shrubs ishigher for Sabina chinensis,Photiniax fraseri,Pyracantha fortuneana,Ligustrum sinense,Pittosporum tobira,etc.The highest number of trees used in frequency is Pinus thunbergii,followed by Sabina chinensis,Celtis sinensis,Cedrus deodara,Photiniax fraseri,etc.The health of the plant species In the samples can be rated as about 88.4% of the total,the other 11.6% of the plant is medium level;Qingdao coastal greenbelt plant community landscape every seasons has the scenery to be rewarded,the seasonal change is abundant;The arbor layer covering of Qingdao coastal green plant landscape is moderate,the shrub layer cover is smaller,and the covering degree of the floor is generally higher.(2)In the landscape of the plant community,the coastal park greenbelt,the majority of recreational plant communities,vertical structure with a half open and covering type of plant-based space,configuration mode with tree-grass and tree-shurb-grass type.The vertical structure of greenbelt plant community in coastal square is mostly open and half open type of plant space,ornamental plant community configuration mode is the most common,configuration mode to shurb-grass type and tree-shrub-grass type.The vertical structure of the plant community in coastal ribbon greenbelt is dominated by completely closed plant space,and the configuration mode is mainly of tree-shrub type and tree-shurb-grass type.(3)Some problems existed in the community landscape of Qingdao coastal greenbelt,such as the insufficient abundance of plant tree species should be increased appropriately,the number of plant shear type application should be appropriately reduced,the number of flower application is not enough,need to increase the use of appropriate,color leaf and aromatic plant quantity should be the development of colorful fragrance,vertical greening landscape is badly needed to improve,some areas of plant landscape need to further enrich the level.(4)The plant landscape design of coastal greenbelt should follow the first investigation and collecting data,then select the appropriate plant material and configuration mode,and consider the regularity of the dynamic succession of plant communities and establish a relatively stable artificial plant community.At design time,we should always adhere to the principle of functional,applicability,ornamental,diversity,uniqueness,culture and humanization.
