西安洒金桥片区城市更新研究

Study on Urban Renewal in Sajinqiao Area in Xi’an

围绕历史街区或历史街巷开展的城市更新工作通常因涉及诸多问题而难以推进。研究以西安市洒金桥片区为对象,通过分析其现状特征,总结其近20年数次尝试更新改造但收效甚微的原因,提出以满足居民、商户、游客、管理者的共性诉求为核心的更新思路。针对承载片区核心功能的主街,通过明确功能定位、剥离过境交通服务功能、确定红线划定原则和道路断面、进行交通分时段管控和片区微循环组织、加强公共交通覆盖等手段,达到优化街道空间的目的。研究认为,在历史街区或历史街巷这一特殊环境中,交通优化可以作为城市更新的抓手,在满足共性需求的基础上,为后续的历史街区改造工作奠定良好的基础。

The urban renewal of historical blocks or streets is often difficult to be promoted forward due to various problems.This paper takes Sajinqiao area in Xi’an as the object,analyses its current characteristics,summarizes the reasons for the attempts of renewal with little effect in the past 20 years,and proposes the core renewal idea of meeting the common demands of residents,merchants,tourists and managers.For the main street that carries the core functions of the area,the goal of optimizing street space is achieved by clarifying its functional positioning,stripping off passby traffic services,determining the principles of red-line delineation and road cross-section,implementing time-division traffic control,organizing micro-circulation of traffic in the area,and strengthening public transportation coverage.This paper suggests that in special environment like historical blocks or streets,traffic optimization can be trated as a trigger of urban renewal.It establishes a solid foundation for subsequent historical block renovation on the base of meeting common needs.
