近百年来扬州市居住-工业空间关联演化及机理分析

Evolution and mechanism analysis of residential-industrial spatial association in Yangzhou city in recent 100 years

空间关联是产城融合问题研究的理论和现实基础。以扬州市居住-工业空间关联为研究对象,基于近百年历史地图等数据,采用热点分析法、蜂巢网格法对居住-工业空间关联强度进行测算,对微观空间关联形态进行分析,揭示两者中长期、微观尺度关联模式及一般机理。结果表明:①居住-工业空间关联强度经历了强-弱-强的演化过程,两者存在紧密的时空对应关系。1949年之前及计划经济时期,居住空间和工业空间紧密融合;住房体制"双轨制"及市场化时期,两者日渐疏离;近年来,随着工业企业的转型升级,居住、工业、服务业空间出现了产城融合的新趋势。②居住-工业的关联形态从内圈层向外,由自由无序转向规整有序,反映了居住空间由产业从属空间向独立、主导空间转化的历史进程。③居住空间建设主体、工业产业类型、居民通勤条件、外部空间影响是空间关联演化的主要因素。

Spatial association is fundamental in understanding the theory and reality of the cityindustry integration. This paper investigated the association between residential and industrial space based on historical maps and other data. Hot spot analysis and honeycomb grid method were used to quantify the association. The association was also analyzed at micro level to reveal its general mechanisms, and long-term and micro-level pattern. The results show that:(1) there is significant spatio-temporal association between the residential and industrial space,which experienced an evolution process featured by a strong-week-strong pattern. The two kinds of space were highly integrated before 1949 and planned economy period, but were gradually separated during the double-track period and the market economy. There is a new trend of the city-industry integration of residential, industrial and service space during the last decade driven by industrial upgrading.(2) The spatial pattern of the residential-industrial association transformed from arbitrary and irregular to consistent and regular, which reflected the transforming process of the residential space from industry-dependent to residencedominant.(3) The evolution of the spatial association between residential and industrial space was driven by four major factors: the main body of residential space construction, industrial types, commuting conditions, and the influence of external space.
