Study On The Green System Of Xi'an City

Urban green space system is a unique urban ecosystem in the implementation of"pollutant carrying spit new"negative feedback mechanism subsystem; improve the environment is to ensure the stability of the urban ecosystem necessary component of urban biodiversity conservation as an important base ; City is to achieve a sustainable development infrastructure. The construction of green space system can improve and enhance life-support systems of the urban services. However, due to the delayed construction of the traditional green, China's urban green space has long been part of the planning system is weak, and from the leadership, planning officers to the public's lack of awareness of green space systems, not from the point of view, the green indicator system is not perfect, the general The rate is limited to green, green coverage and per capita public green targets, and these indicators can not fully reflect a city's green of the problem, and do not reflect the city's green space layout and the structure and function of the coupling relations.This study apply ecology, landscape ecology and urban planning principles and methods of Xi'an green system for analysis to find out the status quo in green type of structure, space structures, plant and matching green landscape, and other aspects of the existing problems. On the basis of those, put forward the principle of the planning system, planning ideas of green land system in Xi'an. Then give some advice about overall planning proposals on the green system in the planning structure, planning and characteristics of green area planning.This paper carries on the historical relics in Xi'an, green residential areas and road systems research, select the typical case analysis from the three types of green space in this system, on the basis of summing up a greenbelt system in Xi'an existing problems and proposed a feasibility Views of the solution: the relics of relying on historical sites reconstruction or restoration of the traditional landscape pattern on the form of parks, street trees as the main form of linear patterns of green, the traditional method of cultivation line (ring) Park, to lawn and geometry - Logo planted mainly concentrated form of green space systems, such as Green Square to the planning concept of the residential area of green space system landscape design, construction of the ecological point of line with the planning concept of city streets green plants, the landscape made specific planning Ideas.
