| Guangzhou is an international big city,population growth at 6.5% per year the proportion increased year by year,residential construction area in recent years,the annual number of new construction area of growth,impact on the urban greening landscape is more and more big,focusing on ecological civilization and livable city construction,residential comprehensive landscape environment in the minds of customers leading constant weight factor worse,while residential green landscape is an important part in the integrated environment,strengthen the construction of green residential area is becoming more and more obvious.The purpose of this study is to proceed from the case of Nansha Downing residential area,respectively from the analysis of garden plants and the two main aspects of the construction of the greening landscape in the residential area.This paper expounds the elements of the greening landscape construction of the large residential community in the suburbs of Guangzhou and the promotion ideas of the greening landscape construction,and the results of this study and analysis.A structure improvement on community species existing in the green landscape change and color change of single plant seasonal characteristic is not obvious and other problems.First,through field investigation,there are 64 species of garden plants applied in the residential area,including 26 species of trees,1380 plants,19 species of shrubs,22467 plants,18 species of ground plants,203090 species,1 species of lawn plants,and a lawn area of 12300m2.This paper makes a statistical analysis on the life style,phenology,landscape characteristics,plant configuration and maintenance management of the garden plants in this residential area.Second,about community species existing in the green landscape change and color change of single plant seasonal characteristic is not obvious and other problems.To solve the above problems,the key lies in the optimization of plant species composition,plant resources and seasonal promotion has different color features of the proportion of four seasons.In plant life form structure,proposed to increase the plant space bottom has obvious color characteristics and seasonal ground cover plant species.Third,the key to improve the design and construction of greening landscape in residential area is to improve the linkage between design and construction of green landscapes,enhance the understanding of landscaping designers in the construction process of green landscapes,and improve the level of greening engineers in reviewing green drawings.At the same time,we should establish the standard system for the specification design of the greening seedlings,and apply different sizes of greening seedlings to different building scales.The three-dimensional angle of the garden seedlings is grasped with the standard of space and human perception of space.Determine the appropriate proportion of plant specifications and planting density.In the choice of tree species,Guangzhou should be the main species of the southern native species,and the characteristics of South of the Five Ridges should be highlighted.And improve the linkage of design and construction in the construction process of residential landscape.Fouth,on the planning and layout of residential areas and the promotion of the spatial allocation pattern of landscaping plants.The key is that the planning and layout of the residential area and the pattern of greening and planting should be flexible and varied,and can be rationally allocated according to the different functional areas in the residential area.It can not only reach the visual and ornamental needs of greening landscape groups,but also form the needs of road guidance and psychological needs of households,which are the structural elements of spatial composition.The greening landscape of residential area can form different scale and morphological changes of plant landscape space through different combinations of plant communities.In the effective supporting environment,the visual focus of space will eventually form. |
