The Research Of Urban Three-dimensionalization

This thesis, responding to serious problems caused by lacking space resourcesduring urban construction, aims to put forward a resolving approach-- urbanthree-dimensionalization.Under the background to construct saving form and harmonious cities in today's China, intensification urban form is a singnificantly effective way to dissolve the contradictions between the shortage of urban living space resources and the demand for urban development, and estalish highly-efficient urban operation system. Theresearch topic -- urban three-dimensionalization is urban basethree-dimensionalization , it is one expression of the intensification urban forms, in order to construct highly-efficient urban operation system under the existing situation of lacking urban living space resources .This dissertation attempts to view the form of urban three-dimensionalization as an research program by discussing the development of urban three-dimensionalization and the urban three-dimensionalization system and urban three-dimensionalization operation system.This dissertation is divided into three main parts. The first part is to carry out ananlysis on urban practices and development requisitions, which are related to urban three-dimensionalization, on aspect of urban form and function. Taking as urban bases a penetration point, it is to explore the practical base and value of existence and development of urban three-dimensionalization. The second part makes comparative analysis on urban base three-dimensionalization system. Based on the spatial structure of urban bases, applying the theory of urban design and system theory, it is to analyze the factors, structures and functions of urban base three-dimensionalization system, to establish the evaluation system of how to design urban base three-dimensionalization system. The third part is to research the relative implementation mechanism of urban three-dimensionalization. From the point view of urban design immaterial research, it is to explore the advantaged conditions to ensure the implementation and development of urban three-dimensionalization, and to figure out the preliminary evaluation on its implementtion requirements and devlepment future, as well as the case studies relative to the research achievements.By means of the three parts' discussion, this dissertation reaches main conlusions: First, the essence of urban three-dimensionalization is to offer a kind of"harmonious" urban form structure or "urban conformation"--the urban basethree-dimensionalization system, it is an important measure in the field of urban design to integrate urban facotrs. Second, urban form is three dimensional, which not only is about that the exterior form, but the more important is about the urban structure or "urban conformation", urban design should emphasize the structure and "conformation" relationship of urban form. Third, it is essential for urban development to break through the management mechanism of zoning urban construction, to change the enclosed research mechanism of relative subjects, and to undertake systematically integrate on different fields of urban construction. Fourth, it is not to mean that cities have to be three-dimensionalization, furthermore all cities should be three-dimensionalization. However, urban three-dimensionalization is the conflicting result between urban form and urban development. It is one of the efficient ways to solve urban problems, and also one of construction measures of intensification urban form.
