Study On The Influence Of The Selection And Arrangement Of Trees On Landscape Architecture Lighting Design

It is the most important element of nature,giving the earth heat and heat,and giving the illuminated scenery with unique charm.Trees as one of the elements of the garden,is the garden space relative to the building,indoor and other space one of the biggest differences in the garden design plays a vital role.Natural light and shadow has been in the field of architectural design and interior design as a designer to express the internal space and external skin one of the most important means.In the garden design,light and shadow is usually only the use of unconscious,but still show a huge landscape and functional value,but because of the changing light and nothing,and the garden space is much higher than the complexity of building and interior space,the lack of corresponding discussion With research.This paper explores the role of light and shadow in the garden and how to construct the specific functions of the garden by configuring the trees to analyze the morphological types of garden trees and the role of different types of trees in different spatial light and shadow design.Based on the characteristics of light and shadow,the characteristics of natural light and shadow,the paper puts forward the role of light and shadow in garden by combining three ecological elements of environmental ecology,public behavior and visual landscape.Followed by the classification of tree species and garden trees shade of the study.From the practical point of view,according to the crown height and the characteristics of the external shape,the trees are divided into tower type,egg type,flat ball type,palm type,branch type,hanging type.The shading area of shade was analyzed by shading area and shade.The shade area was determined by crown width,and the shade area had a certain correlation with leaf area and crown width.And then combined with the field survey of natural light and shadow applications in the garden space of Guangzhou area,the paper summarizes the role and application of six kinds of trees in walking space and communication space.Among them,the egg crown of the crown is moderate,under the branch space is higher,can be in a variety of different space are very good to play the role of regulating light and shadow.Crowns to carry out,the shade area of large flat-type trees and branches of trees in the performance of each space is also better.Palm treeshave poor shading effect and are unsuitable for use in static,static spaces such as walking and meditation,but have a large space in the branch space that provides plenty of bright space for public activities while their architectural shapes can be used Manufacturing controllable light and shadow effects,more suitable for use in dynamic space.The diameter of the tower trees is narrow,the space under the branches is low,and the effect of the adjustment of the space and light is poor.On the basis of this,the influence of different types of trees on the dynamic changes of light and shadow was studied by simulating the software with several successive years.Finally,we discuss the interrelation between light and shadow and garden space,garden interface and garden boundary,and draw the way of introduction of light and shadow into garden.Modern garden design pursuit of artistic,functional and ecological unity,in addition to buildings,water,plants,terrain and other elements of the entity,the light and shadow of such intangible elements should also be taken seriously.Natural light and shadow of the nothingness and the combination of trees and other elements of the complexity of the landscape,to the garden lighting control and design to bring great restrictions and difficulties.In the design and configuration of the tree through the selection of garden light and shadow,the designer can focus on the main activities of space analysis,select the appropriate tree species and configuration,combined with other elements of the garden,the light and shadow into the garden space.
