容积率是城市控规的强制性内容和核心控制指标。目前容积率的确定主要依据城市规划管理技术规定和经验,定量分析不足,且不同规划层面的容积率控制要求并不一致。研究以居住用地容积率为对象,基于上下位规划一致性的要求,构建居住用地容积率影响因子的评价指标体系,尝试将总规与控规对容积率的控制进行衔接,将总规对建设强度的限制要素的空间规划表现为容积率分区,并指导控规容积率的确定,从而实现从总规-分区-控规三个阶段对容积率控制的一致性。
Presently FAR is mostly decided by regulation or experience, but rarely by quantitative analysis. FAR at diferent level plans is inconsistent. The paper establishes evaluation system of FAR relevant elements, studies FAR zoning of master plan for regulatory planning, and realizes consistency of FAR at master plan, district plan, and regulatory plan.
