超大城市公共空间治理的规划策略体系构建——以北京为例

Construction of Planning Strategy System for the Governance of Public Space in Metropolis:Taking Beijing as an Example

随着城镇化进入存量提质的下半场,公共空间品质提升成为提高规划治理能力的核心议题之一。但在具体的实践操作中,经常出现因资源错配与权力失衡而导致的空间异化、品质不保等问题。文章依托近年来完成的北京城市公共空间规划系列研究,从观念、政策、资本和技术四个维度剖析制约空间品质提升的深层次因素,旨在反思和厘清空间品质中蕴藏的价值层次及相互关系,明确公共空间治理的基本价值导向,总结归纳兼具普适性与实验性的规划策略体系,以此重构公共空间作为城市公共产品、生活场所和人文载体的价值伦理,重塑中国特色的公共空间生产模式。

As urbanization has entered the stage of improving quality,the enhancement of public space quality has become the core focus on efficiency in planning and governance efficiency.However,there are always lots of problems of space alienation and quality shortage due to resource mismatch and power imbalance.Based on a series of recent studies on urban public space planning in Beijing completed in recent years,this paper analyzes the underlying causes restricting spatial quality from four dimensions which are concept,policy,capital and technology.This analysis aims to reflect on and clarify the values and their interrelationship regarding"quality"which establish clear the basic value orientation of public space governance and summarize the planning strategy system of both universality and experimentality.According to these contents,the value of ethics of public space could be reconstructed as the triple attributes of urban public product,living place and humanistic carrier to reshape the public space production model with Chinese characteristics.
