【摘要】 天津市中心城区现存大量老旧小区,多建于上世纪八九十年代。近年来,天津市出台了多项关于老旧小区更新改造的政策文件,对老旧小区更新展现出极大关注。在既往的旧区更新过程中,一度出现“大拆大建”的资源浪费现象,继之前的几次大规模老旧小区更新改造行动后,天津市现存老旧小区大多结构完好、质量较高,在及时维护的基础上可以继续使用较长的时间。这也引发了几个问题:我国是否存在建筑平均寿命过短的问题?建筑寿命问题是否为现有的城市发展进程埋下危机?有怎样的危机?本文从城市规划角度出发,以天津市中心城区为研究区域,依托建筑寿命及其影响因素研究提出天津市老旧小区更新改造策略。研究中用到了Arc Gis地理信息系统与SPSS统计分析工具。本文的主要研究内容分为三个部分:(1)根据相关文献对天津市住宅建筑历程进行阶段划分,统计天津中心城区老旧小区存量信息和不同阶段的时空分布情况,计算不同阶段的老旧小区剩余寿命;(2)统计天津市中心城区老旧小区的建筑平均寿命,分析建筑寿命与其影响因素间的相关性,并从社会视角对相关性进行解释,并预测未来不同因素对建筑寿命的影响情况。(3)基于建筑寿命研究提出天津市典型区域存量老旧小区更新优先级。研究主要发现:天津市存量老旧小区大多为上世纪八九十年代建成的,总体上在和平区分布比较密集;历史商业街、大型公园、三甲医院与住宅建筑寿命有相关性;和平区西侧、新兴街道南部、劝业场靠近海河风景线一带和南京路沿线东侧局部位置的老旧小区可以考虑优先更新。本文的研究意义在于创新性地将log-rank检验、cox回归方法引入建筑寿命体系,实现了建筑寿命研究方法体系的创新,划定了典型区域老旧小区更新改造优先级。更多还原

【Abstract】 Nowadays,there are a large number of old residential quarters in the downtown area of Tianjin,most of which were built in the 1980s and 1990s.In recent years,Tianjin has issued a number of policy documents on the renewal and renovation of old communities,showing great concern for the renewal of old communities.In the past renewal process of old districts,there was a phenomenon of resource waste caused by"massive demolition and reconstruction".After several previous large-scale urban renewal actions,most of the existing old residential areas in Tianjin are well-structured of high quality,and can continue to be used for a long time on the basis of timely maintenance.This also raises several questions:Is there a problem of short average lifespan of buildings in China?Is the issue of building lifespan laying a crisis for the existing urban development process?Are there any kinds of crises?This paper will start from the perspective of urban planning,locating the city center of Tianjin as the research area,and put forward the problem of old buildings in Tianjin and propose a community urban renewal strategy based on the study of building life and its influencing factors.Community urban renewal strategy.Arc Gis geographic information system and SPSS statistical analysis tools are used in the study.The main research content of this article is divided into three parts:(1)Based on relevant literature,the process of residential construction in Tianjin is divided into stages,and the inventory information of old residential areas in the central urban area of Tianjin and the spatiotemporal distribution of different stages are collected to calculate the remaining lifespan of old residential areas in different stages;(2)Calculate the average lifespan of buildings in old residential areas in the central urban area of Tianjin,analyze the correlation between building lifespan and its influencing factors,and explain the correlation from a social perspective,and predict the impact of different factors on building lifespan in the future.(3)Propose the priority of updating old residential areas in typical areas of Tianjin based on the study of building lifespan.The main findings of the study are that most of the existing old residential areas in Tianjin were built in the 1980s and 1990s,and are generally densely distributed in Heping District;There is a correlation between the lifespan of historical commercial streets,large parks,tertiary hospitals,and residential buildings;Priority should be given to the renewal of old residential areas located on the west side of Heping District,south of Xinxing Street,near the Haihe Scenic Line in Quanyechang,and on the east side of Nanjing Road.The significance of the research of this article lies in the innovative introduction of log rank test and cox regression methods into the building life system,achieving innovation in the research method system of building life,and delineating priority levels for the renovation of old residential areas in typical regions.更多还原
