The study about the integrated planning theory of surface and underground urban space

摘要

As the development of the economic of China and the acceleration of urbanization, metropolises have run out of land resources. The increasingly serious urban space constraints compel us to rethink profoundly the traditional urban planning theory. The traditional urban planning theory pays attention to the two-dimensional space perspective of the ground and the aboveground to solve the problem on urban development, while, the modern urban space is a three-dimensional space system which is made up of above and below parts of the space. Therefore, how to arrange appropriate functions of urban space and form a favourable urban function system according to the surface and underground urban space, is the problem needed to be solved by current urban planning. Planning urban space from the perspective of the integration of surface and underground space will re-examine and re-evaluate the urban space growth boundary and the bearing capacity, so that it will bring the innovations to theory, method and technology of traditional urban planning.
