A Rational Approach to Urban Density Zoning: the Case of Shenzhen Special Economic Zone

土地利用的总目标对城市范围内各个区域不同类型的土地使用和发展强度进行划分,以提供一套合理的土地发展模式与城市整体发展战略相协调。

The Extraordinary pace of urban development in China requires the rationalization of decision-making in planning. Having discussed the location theory of microeconomics and the worldwide experiences in urban density control, the paper introduces a rational approach to urban density zoning including three-level planning policies, and its application in the case of Shenzhen Special Economic Zone. Firstly, the density on the citywide scale is based on the appraisal of environmental standards regarding the balance of demand and supply of urban land. Secondly, the urban area is divided into several density zones according to the basic model following general criteria of location theory and the modified model based on special criteria of other considerations. The floor areas of different types of buildings are then allocated according to the urban density zoning. Thirdly, the lot-based density is guided by micro-level criteria of sub-allocation with urban blocks as the spatial unit for the control of floor areas.
