【摘要】 该文以长沙化龙池历史街区(2007年-2012年)功能、空间的演化过程为案例,研究城市历史街区自下而上的演化机制;同时,对城市统一更新改造后的历史街区予以跟踪,反思政府主导的,整体式的历史地段更新方法在资金筹措、功能组织、风格引导等方面的缺失。该文通过实地调研、访谈、文献查阅等工作手段,梳理还原了长沙化龙池历史街区在2007年之后的演化历程。2007年,在市民经营的推动下,化龙池发展为长沙小酒吧的聚集地。小规模、民间自发的改造活动对该历史地段空间体系的演变产生了主导性的作用。历史街区的自组织再更新有利于构造城市公共环境丰富的空间层次以及大量的人文细节,实现历史地段的动态的,自适应的可持续更新。但由于非理性因素的影响以及涨落周期的不确定,自发的、自组织的更新模式不能解决所有的城市问题,仍需要合理的控制与引导,以适应城市快速发展的需求。更多还原

【Abstract】 This paper focus on the bottom-up evolutionary mechanisms of urban historic block,takes the spatial and program evolution from 2007 to 2012 in Hualongchi historic block,Changsha,as case study.In the mean time to track the historic blocks which are renewed by government,with particularly interest in what are the weakness of the municipal historic blocks renewal programs,especially in the way of financial solution,program layout,patterns guidance.This paper based on the means of field work,interview and literature consult,to restore Hualongchi historic block process history since 2007.In 2007,leading by citizens voluntary bars business operates process,Hualongchi develop into a little bar street and famous in Changsha.Voluntary block renewal behavior has become a leading factor in small scale historic block spatial system evolution process.The result shows the process of self-organization updates in historic block is conductive to rich the details and spaces,leads to a dynamic and continuously renewal process in historic block;But because of the irrational factors and the irregular fluctuation cycle,self-organization renewal process also needs reasonable control and guidance to adapt the rapid development.更多还原
