总体城市设计中高度和强度控制的双基准模型

作为非法定规划,总体城市设计成果需要提出整体性的高度和强度控制分区,通过控制性详细规划等法定规划实现对建成环境的控制和引导.然而,传统的专题规划与城市设计框架下的开发控制分区方法均在一定程度上隐含了"经济优先,兼顾美观"的公共政策价值取向,并不适用于所有城市.为此,基于效率对强度、美学对高度的直接影响,针对云南省大理市总体城市设计提出了高度和强度分区的双基准模型,并通过强度与高度分区的匹配检验,实现了总体城市设计对空间形态的双管控,兼顾了开发控制的经济原则和美学原则.

Dual-Model of Intensity and Vertical Control in Overall Urban Design

As a non-statutory plan, in overall urban design, a holistic vertical and intensity control zoning should be proposed to achieve guidance of the built environment through the statutory planning system in China. However, these traditional technical routes usually give priority to economy with consideration to the artistic value, which cannot be applied to all cities. Therefore, a dual-model of vertical and intensity zoning was proposed in the overall urban design of the city of Dali in Yunnan province. The basic vertical zoning is independently derived from artistic principles while the basic intensity zoning independently originates from economic principles. These two zonings are mutually modified to ensure that the vertical height and intensity of each block are matched with each other, through which the economic and artistic principles are both given consideration to.
