A Study On The Structure Of Urban Green System

With the increased attention people paying to urban landscape and environmental issues,the planning of scientific urban green system is now becoming more important than ever in urban planning and construction .Due to being the foundation frame,the structure of urban green system plays an very important role on planning urban green system.　This thesis takes the structure of urban green system as the object of research and tries to explore systematical ways of planning it with analyzing the meaning and developmental tendency.　Based on this purpose,the study had taken five steps: 1,The first part defines the conception about the structure of urban green system,analyzes the function of the structure planning,delimits the area of study.Then,after analyzing the theories about research on urban green system in the world,the thesis summarizes the order of development,practical experience and inevitable tendency . 2,After analyzing the intrinsic characters and the connection with urban development from the structure of planning and over arrangement structure,the author pays more comprehension to the structure of urban green system and cognizes the order and the connected factors which influence the planning. 3,The paper analyzes the problems and causes existing in this field of our country,explicates that it is certainly and necessary to systematizing the structure of urban green system with the development of our cities,discusses the functions of the systematic structure in ecological environment,economy,life,landscape etc.　Then an inevitable tendency that the structure of urban green system is becoming more systematic than before is proved. 4,Being aimed at the meaning and the practicality of Chinese urban green system planning and construction,the thesis concludes the targets and principle of the planning and tries to gain a series of practicable methods of planning.　The chapter is the most important part of this thesis. 5,Last,basing on the above research,some examples are discussed in order to put the above methods into practice.
