The Primary Research Of The Design Of The Urban Fifth Surface Form Under The Overlooking Viewpoint

In recent years, along with the economic and society development and theimprovement of science and technology, our country’s urbanization level increasedyear by year. With the improvement of population density, urban traffic and landconstraints situation intensifies, high-rise buildings appear in large Numbers, the cityspace to keep the three-dimensional models development, more and more people canoverlooking the city from the work and life place. At the same time, along with thedevelopment of aerospace industry, people get more and more opportunity tooverlook the city from the sky,the city fifth surface is not that of the high above, itcomes to people’s sight gradually.The paper research around the proposition of the city fifth surface, the articleis divided into four parts. Firstly,starting from introducing the current state that thehuman viewpoint is shifting from the ordinary ground view to the bird ’s-eye view,the author analyzes the different overlooking viewoint including the higher groundposition, city high-rise buildings and the overlooking viewpoint in air vehicle, andthen put forward the proposition of the city fifth surface and classified according to itscharacteristic,after that,the paper lists the existing problems and put forward the goaland the significance of the research.Secondly, according to the characteristics of urban fifth surface and the researchscope, raised the constituent elements of the urban fifth surface, then analysed thefactor that impact on urban fifth surface form,including the natural environment,science and technology, economic development, social system, the customs andculture, urban property, and city features.Thirdly, after the analysis and descriptions above,putting forward the the basisand principles of the form design of the urban fifth surfacs, and rised the visualcontrol elements of the urban fifth surface based on from the color matching,lightingand so on. Then analysed the relationship between the urban fifth surface and urbantexture, and then put forward the urban fifth surface as special expressions and character of the urban.Finally, put forward new applications and the development directions of theurban fifth surface, explore the urban fifth surface as a potential space in thedevelopment of the city, and the new view point and starting point of the urbandesign in future.and choose relatively typical areas of urban fifth surface in Qingdaofor analysing,and then put forward the design inspiration and conclusion...
