重庆市主城区产城融合评价及其规划应对

Evaluation and Planning Strategies on Industry-city Integration in Chongqing Main Area

产城融合是一项涉及面广且复杂的系统工程,定量化科学分析产城融合度是理论研究与实践工作的基础,也是学科与业界的难题。文章从现状问题导向和规划源头切入,集成手机信令、公共开放数据、居民出行调查、交通运行数据、岗位抽样调查、用地遥感解译、统计数据等多源数据,将大数据相关分析与小数据因果分析方法有机整合,构建总量职住比、实际职住比、独立指数、潮汐比和产城用地比等系列指标,研究确定合理的阈值,从现状和规划两个方面,以及槽谷、片区和组团三个空间层级对重庆市产城融合水平进行综合分析,评判职住关系与产城关系的合理性、匹配性及变化趋势,总结和提炼存在问题,在此基础上提出规划应对策略和相关政策建议。

Industry-city integration is a complex and systematic project.Quantitative analysis of the degree of industry-city integration is the foundation of research and practice,and it is an agreed difficult issue of the profession.With data from multiple sources such as cellphone signals,public open data,residents outgoing investigation,traffic data,job sampling investigation,land use remote sensing,statistical data,this paper takes parameters including employment-residence ratio,independence index,tidal ratio,industry-city land use ratio,etc.,and integrates big data and small data analysis methods for the evaluation of industry-city integration.By conducting quantitative studies of the spatial units such as trough valley,zones and blocks in Chongqing's main urban area,it analyses the rationality,matching,and changes between employment and residence as well as industry and city,concludes five problems,and proposes planning strategies and policy suggestions.
