基于CiteSpace的国内外城市生态修复研究进展以及对西北地区的启示

Progress of Domestic and Foreign Researches on Urban Ecological Restoration Based on CiteSpace and Their Enlightenments to Northwest China

为综合比较国内外生态修复领域的研究现状与热点演进,采用文献计量的方法。通过对1992—2017年CNKI数据库1 356篇、WOS核心合集957篇生态修复主题文献进行分类统计,从刊文量、篇均被引数、共现关键词、主要期刊和主要研究机构等方面进行了对比分析。结果表明如下。1)国内外生态修复研究发展态势良好。工业发达国家走在前列,中国东部和中部地区紧跟其后,西部地区关注力度不够。2)国内外生态修复研究的热点演进不同。国际主要关注河流修复与实践、城市界面与水生生物区系、采煤塌陷区和风险评估、生态系统服务和淡水大型无脊椎动物、湿地缓解和限制因素分析。国内主要集中在河流修复、海绵城市和生物多样性保护等方面。3)国外生态修复研究的合作强度、持续性、系统性和学科交叉性明显高于国内。未来中国,尤其是西北地区的生态修复研究应在政策支持、生态修复技术、多尺度耦合和跨部门合作等方面进行加强。

The bibliometric method was used to comprehensively compare the research statuses and research focuses in the field of ecological restoration at home and abroad.1,356 articles and 957 articles on ecological restoration published from 1992 to 2017 were collected from the CNKI database and the WOS core collection,respectively.These articles were compared from perspectives such as the publication number,citation number per article,co-keywords,major journals,and major research institutions etc.As indicated by the results,1)There is a good development trend for domestic and foreign researches on ecological restoration.Developed industrialized countries are leading the way,followed by eastern and central regions of China,and the western regions of China are making slow progresses.2)Researches on ecological restoration at home and abroad focus on different topics.Foreign researches mainly concentrate on river restoration and practice,urban interface and aquatic biota,coal mining subsidence areas and risk assessment,ecosystem services and large freshwater invertebrates,wetland mitigation and limiting factors.Domestic researches primarily focus on river restoration,sponge city and biodiversity conservation.3)The collaboration strength,persistence,systematicness and interdisciplinary nature of foreign researches on ecological restoration are obviously superior to those of domestic researches.In the future,researches on ecological restoration in China,especially in the northwestern regions,should be strengthened in terms of policy support,ecological restoration technologies,multiscale coupling,cross-sector cooperation etc.
