Construction Of Three Dimentional System In City Park

With the development of society, the 3-D development and construction of above ground and basement, the relationship of citypark and the city become increasingly complex and diversified, also bring challenges to the construction of city parks. The three-dimensional system of City Park Conforms to the needs of urban development in three-dimensional,particularly with the background of the lack of urban land resources and the shortage of city open public space,it becomes one of the ways to solve these problems.It makes the land more intensive and complex, the connection of various urban functions more effective.At the same time,the three-dimensional system of City Park has improved the image of the urban and ecological environment, provided citizens with recreation areas, and enriched the city park space. Most of present study concern about the integration of urban-dimensional systems on the point of Urban Design, and few literatures study from the perspective of urban park space.In this context, this article attempts to take the three-dimensional system of City Park as an object, makeing analytical analogy to large numbers of actual cases, trying to find their similarities and differences. This article discussed from concrete to abstract and eventually rose from the theoretical level to practice level. The article was segmented in four areas:three-dimensional space of the city park system, system configuration, system type, construction of system.This thesis is mainly divided into 3 parts. The first part defines the relevant concept in the research, Expatiate that three dimensional space in city park is the recreational space which overlaps or intercrosses city park with buildings, transportation, etc. horizontally and vertically, in order to make the space extend in different dimensionality and form a kind of space in various types and levels, so that provide an pretty and cozy recreational space for people. Traits of this space are summarized that are organically related system, multiple structure levels, multiple functions, multiple routes, undefined boundary and modern style, then makes an initial recognition on research object in the function and application. The second part makes an analysis on the system from the component elements and configuration. It classifies the actual cases and they are sort out into three types:ground-underground base level system, ground-air base level and underground-ground-air base level system. And it concludes the constitution and configuration features of each type. The third part, bring forward five principles that are system, aesthetics, humanism, safety and culture. And indicates the construction of the three-dimensional system including system construction (planning level) and the spatial construction (design level). Meanwhile, system construction contains the organization of system function and the arrangement of system framework. Spatial construction includes the shaping of spatial configuration and spatial feature. This part also integrates with the case of Shenzhen ecological square design, to make a further recognition. What is more, the discussion part makes a summary on the content of system construction and the illumination of park construction nowadays. In addition, it also summarizes the shortcomings of this content. To sum up, this thesis could provide some theory production and illumination to the urban park and urban construction.
