中国已改造棕地时空特征及用地模式转换研究——基于荟萃分析方法

A STUDY ON SPATIOTEMPORAL CHARACTERISTICS OF BROWNFIELD TRANSFORMED IN CHINA AND CHANGE OF LAND USE PATTERNS:BASED ON THE META-ANALYSIS METHOD

棕地已成为城市更新和土地再利用的重要承载和热点研究领域,但我国目前对于棕地数量、位置信息和改造模式等基本情况尚不十分明确,这对掌握全国棕地信息、指导城市空间规划和棕地再利用造成了诸多障碍。本文基于荟萃分析,通过提取CNKI、WOS、中国工业遗产名录等已发表文献中的已改造棕地信息,作为中国棕地的典型代表和数据来源,分析中国已改造棕地在总体表现、阶段性、地块因素等方面的时空特征,归纳其再利用模式类型及转换特征。本研究有利于丰富和深化中国数据缺失背景下的棕地空间研究,可以为中国棕地再开发、土地整治和增强城市活力提供科学依据和决策参考。

Brownfield has become a heated research topic in the field of urban regeneration and land reuse.However,the number of brownfields,location information,and redevelopment modes in China are still unclear,which has brought about many obstacles to obtaining the brownfield information,guiding urban spatial planning,and re-utilizing the brownfields across the country.Based on a meta-analysis,this paper extracts the information of transformed brownfields from the literature published in the China National Knowledge Infrastructure(CNKI),Web of Science(WOS),and China Industrial Heritage List,and uses it as the typical representative and data source of China’s brownfields.Then,the paper analyzes the spatiotemporal characteristics of brownfields already transformed in China in terms of the overall performance,stage,and plot factors,and summarizes its reuse pattern and transformation characteristics.The study is conducive to enriching and deepening the research on brownfields in the context of lack of related data, and can provide a scientific basis and reference for the decision making for China’s brownfield redevelopment, land consolidation, and urban vitality improvement.
