Reasonable Choice Of Chinese Urban Residential Height

The level of urbanization reflects a country economic structure, infrastructure and people level of modernization. The sustainable development of urbanization for our country has important significance. Urban construction planning in the development of urbanization has been in a leading position, and is the skeleton of the city. In the last century, in order to adapt to the speed of urbanization development, and solve the living problem of population, the cities begin to build high-rise buildings. Because high-rise building volume grows, the city produce a set of problems, including serious environmental pollution, traffic congestion, increasing hidden danger and public health problems and others Therefore, the trend of building height controls the sustainability of urban development in the future.Paper summarizes foreign experience and explore the urban reasonable residential height.The paper use a literature study, the paper analysis high buildings and low-rise buildings from saving land, the cost of economy, human care, environmental issues, safety and ect.. Analyse various factors and identify the best architectural layers. Based on our national conditions low-rise buildings is impossible to build in large area. The best model is the use of multi-layer and high-density residential. 7-9 floors are the best, and can realize save the land with the largest and lowest cost.Secondly, research the status at home and abroad of the building height form. In the United States, Japan and other developed countries, for example, analyze the general law of building height form development. The development of urban construction in the developed countries started with low-rise buildings. With the outbreak of the industrial revolution, the city began construction of a large number of high-rise buildings. The last time, the development of Architecture tends to be more sustainable, back to the living mode of low-rise buildings. According to the law of development, compared the present situation in our country, our country at present is in the second phase transition. The period is a contradictive one that pursuit building height and urban problems appear frequently.Then, analyze the differences between China and foreign countries in the form of building height from the land, population density, building layers and other several aspects. By comparing to Japan, our city has the condition fulfillingbuilding “lowriseing-level” of the “land-intensive”.Finally, the paper describes relations between a multi-layer, high-density residential patterns and the two principles——“urban health and sustainable development”, “people-oriented”. At the same time, pointing out that our country future should promote the development of multi-layer high-density residential patterns from urban land consolidation, community space planning, government policy and other aspects.
