Plant Community Design On The Green-way Construction

Greenway as the important link of open space, such as parks, squares, natural reserves, scenic areas, historical monuments, the Greenland Landscape of residential district, has combining characteristics which with ecology, recreation, landscape and natural resources and historical and cultural resource protection, and also plays an important role in natural habitat protection, recreation ground, the construction, the protection of cultural resources, green space system. The traditional city landscape plants design in the green road construction, widespread species with a single, simple structure, landscape is flat, green ecological and landscape function and the requirement of city development does not match the phenomenon. City greenbelt plant community as the basic unit of city green land ecological system, is the foundation, is to improve the city green space plant community richness prerequisite factor, also represents the development level of city greening plant landscape. This article through to the Guangzhou green road construction in plant communities case design study, breaking the previous city greenbelt plant design and research content is single and limited use of ecology and landscape architecture, with the method of the study of plant community, the relation between the structure and, in order to improve the city greening plant application level, build the ecological health, the beautiful landscape, sustainable development city greening provides a basis, and the Green Road plant community design, construction, conservation management form positive significance, at the same time as the city green road construction to provide related suggestions, has certain theory significance.This paper first makes clear the greenway and plant community design definition, summarized the domestic and foreign green road construction in plant community design research, introduced the research purpose and method, put forward the research framework. Then has analyzed the Green Road plant community composition, ecological characteristics, landscape characteristic. It discusses the plant community in green channel function, then according to the function localization of Green Road plant community in a divided into ornamental plant community, environmental protection type of plant community, popular science knowledge, culture and the arts of plant community type of plant community, the production plant communities in five types of. Discusses the greenway space and recreation content, then according to the type of space will be Green Road plant community is divided into open transparent type, open type, level of semi transparent shielding type, vertical shielding type, full cover type and other types of five.Then it presents the Pearl River Delta green road network planning outline and green Guangzhou city road network construction to generalize, through northern Zengcheng green road planting design as a case study on design, plant community design in green road construction in the practical operation and application. Zengcheng green road planting design is divided into the northern ecological landscape corridor and green road forest belt two part. Ecological corridor part, according to the site types of divided road type, waterfront, green land and farmland type four types, and according to each type, from the landscape features and recreation activities are put forward the corresponding community configuration; green road forest belt portion of the community design, respect local ecological protection under the premise, from the viewing angle of building plant community, with seasonal, color, form, put forward a variety of themes of plant community collocation mode.Based on the investigation and analysis, summarized the design principle of Green Road plant community, community planting classification guidelines and principles of plant selection; then analyzed the Guangzhou Green Road plant community design problems and present situation, mainly for the hierarchical structure is simple, community design of a single structure, species selection lack of variety, lack of green road the project is located area environmental condition analysis, apply mechanically the foreign, field model, finally in the ecological effects, landscape visual effect level, level of social effects of dimensions, and puts forward some suggestions on optimization.This thesis is on the Green Road plant community design is a systematic organization and scientific construction of city, Green Road plant community landscape, in addition to satisfy user's aesthetic appeal and life demand, is to the city construction and the natural environment the adjustment between a coordinating role, is the important way of nature into city. By introducing the natural community structure mechanism, the nature into city, maintain the natural process of integrity and continuity, forming a natural scenery and modern urban life style of city com. Therefore, study on green road construction in city garden plant community design application, the scientific construction of plant community landscape is the realization of protection and construction of city biodiversity important way, also is the contemporary people to achieve the city an important direction of the sustainable development.
