The Urban Design of the Central Axis Area in Nanjing Dongshan Sub-city Area

Abstract：Local governments face the dilemma of the constraint of land resources under the pressure of the high GDP growth requirements, backward industrial structure and the urgency of urban space improvement. Therefore, it' s imperative to improve the efficiency of land use and optimize the form of urban space in urban renewal. However in wide ranges, the basic urban design principles, including compact and flexible urban structure, mixed and efficient land use, well-structured urban space hierarchy and convenient public transit system, have often been insufficiently used in practical planning and construction of the central areas of cities. As for the Jiangning Development Zone which founded in 1992, it' s practical for the operation on the well-managed existing industrial zone that the basic urban design principles should be taken seriously, the strategy of industrial structure regeneration and the distribution characteristics of current property range pattern should be combined with, and the effectiveness of the urban renewal should be reflected.
