Brownfields have attracted increasing attentions from both researchers and practitioners. However, few studies have attempted to make a comprehensive and quantitative review on this topic. This study conducted a scientometric review on the brownfield research from 1995 to 2017 using CiteSpace. The knowledge structure, hot topics, research trends, and gaps were analyzed based on the co-author, co-word, co-citation, and clusters analysis. Six hundred thirty articles from the Web of Science core collection database were selected as the research samples. Results revealed that the research focus has changed from soil remediation technologies to sustainable regeneration methods. The most vital development in brownfield research occurred in the USA, England, Canada, Germany, and China. "Brownfield," "heavy metal," "remediation," "redevelopment," and "sustainability" were the most frequently used keywords. Whereas "management" and "biodiversity" received citation bursts in recent years. Existing researches mainly concentrated on subject categories of environmental sciences ecology, environmental sciences, engineering, environmental studies, engineering environmental, and urban studies. Sustainable regeneration, urban brownfields' regeneration, mental distribution, coal-mine brownfield, and ecosystem service were the identified co-citation clusters and represented the hot topics and emerging trends. The research gaps can serve as a motivation to research on the next generation of brownfields to support the sustainable development. This study provides researchers and practitioners an extensive and intensive understanding of the salient research themes and trends of brownfields' research worldwide.
棕地已引起研究人员和实践者的广泛关注。然而，很少有研究试图对此主题进行全面和定量的综述。本研究使用 CiteSpace 对 1995 年至 2017 年的棕地研究进行了科学计量学综述。基于合著者、共词、共被引和聚类分析，分析了知识结构、热点主题、研究趋势和差距。从 Web of Science 核心合集数据库中选择了 630 篇文章作为研究样本。结果表明，研究重点已从土壤修复技术转向可持续再生方法。棕地研究中最重要的发展发生在美国、英国、加拿大、德国和中国。“棕地”、“重金属”、“修复”、“再开发”和“可持续性”是使用最频繁的关键词。而“管理”和“生物多样性”在近年来受到了引文爆发的影响。现有研究主要集中在环境科学生态学、环境科学、工程学、环境研究、工程环境和城市研究等学科类别。可持续再生、城市棕地再生、精神分布、煤矿棕地和生态系统服务是确定的共被引聚类，代表了热点主题和新兴趋势。研究差距可以为下一代棕地的研究提供动力，以支持可持续发展。本研究为研究人员和实践者提供了对全球棕地研究的突出研究主题和趋势的广泛而深入的理解。
