城市更新大数据平台研究及应用
Research and application of urban renewal big data platform
摘要
Abstract
[Objective]Promoting urban renewal activities using digital technologies is essential to achieve high-quality economic development.This study examines how digital technology can be integrated into various stages of urban renewal,such as real estate rights,planning,construction,completion,and operational management.The objective is to connect all data in the urban renewal process and protect rights related to resources,assets,and capitals involved in these projects.Furthermore,this study drives the industrialization of digital technology,accelerates the digitalization-driven transformation of traditional industries,and explores the transition from a land-based economy to a digital economy,thereby continuously strengthening,enhancing,and expanding China's digital economy.[Methods]This study first examines the existing issues in the complete process management of urban renewal in China and the research status of digital platforms for urban renewal both domestically and internationally.This study then outlines construction concepts for an urban renewal big data platform,proposes a data-driven approach to managing urban renewal,and designs a platform system comprising support environment,data resource,foundational platform,and application system layers.Finally,the issue of information nonshareability is addressed by integrating multiple-source data fusion technology based on metadata to create an urban renewal data system.In addition,data attribute-based model lightening technologies and the integration of building information modeling(BIM)and geographic information systems(GIS)are used to design and develop the urban renewal big data platform.[Results]The big data platform for urban renewal developed using the methods outlined in this study has been effectively applied to urban renewal projects across Wuhan.The platform,which is customized to meet the specific needs of each area,features several fundamental functional modules,including basic information queries,demolition management,asset maintenance,renewal project management,digital delivery,and smart community operational management.This platform,which embodies an innovative examination of urban renewal strategies and methodologies supported by digital technology,facilitates digital management throughout the process of urban renewal.This platform has been deployed and used in various urban renewal projects,such as Sanyang Design City,Wuhan Station,and Wuchang South Station,to effectively manage and control the quality of urban renewal projects and their financial investments.[Conclusions]Urban renewal activities are crucial for assessing the inventory of resources,assets,and capitals within urban districts.Detailed data on these capitals supporting urban renewal initiatives are essential.The big data platform constructed using advanced digital technologies ensures data interconnectivity throughout the urban renewal process and facilitates the quantitative tracking and analytical evaluation of resources,assets,and capitals.Further studies should further examine data standards,data governance,data collection,and platform promotion mechanisms to improve these processes.This study contributes significantly to digitizing the traditional urban renewal industry,supports local governments in exploring new economic development models with transition from a land-based economy to a digital economy,and promotes high-quality economic development.This study shows the transformative potential of digital platforms in urban renewal through in-depth analysis and practical applications,thereby setting a benchmark for future urban renewal developments in China's digital economy.关键词
