城市绿地土壤研究文献的CiteSpace可视化分析

CiteSpace visualization analysis of urban green space soil research literature

【目的】城市绿地土壤的质量直接关系到城市生态效益及各项功能的发挥。分析中外城市绿地土壤研究文献,梳理与总结中国城市绿地土壤研究重点及未来发展方向。【方法】检索中国知网(ChinaNationalKnowledge Infrastructure)和科学网(Web of Science)核心数据库中2012—2021年关于城市绿地土壤的研究文献,利用CiteSpace从发文量、国家及机构分布、代表人物及热点内容、研究重点内容、研究发展趋势及前沿等方面,阐明该研究领域的重点内容及动态发展。【结果】近10年城市绿地土壤研究领域共发表中英文文献1 107篇,其中中国发文总量最多,且主要集中在中国科学院。国内研究内容主要为土壤质量,研究热点从土壤肥力质量到土壤污染,再到土壤改良修复。国外研究内容主要是城市绿地土壤的生态系统服务功能,研究热点从解决城市生态环境问题到提出绿地维护管理策略,再到提升城市生态环境效益。研究前沿集中在重金属污染和城市绿地生态系统。【结论】城市绿地土壤中英文文献的研究重点不同,中文文献更关注城市绿地土壤质量,这与国家政策、城市发展、生态环境保护等有关。而英文更关注城市绿地生态系统,这可能与气候变化、绿色基础设施建设、生态环境效益等有关。图3表5参58。

[Objective]The quality of urban green space soil is directly related to the ecological benefits and functions of cities.This study sorts out and summarizes the research focus and future development direction of urban green space soil in China by analyzing the Chinese and English literatures.[Method]The literatures on urban green space soil from 2012−2021 in the core databases of China National Knowledge Infrastructure and Web of Science were searched,and CiteSpace visual analysis software was used to elucidate the key contents and dynamic development of this research area in terms of the number of publication quantity,distribution of countries and institutions,representative figures and hot topics,research focus,research development trend and frontier.[Result]In the past 10 years,1107 literatures were published in the field of urban green space soil research and most of them were in Chinese.Among the academic institutions,Chinese Academy of Sciences had the largest quantity of publications.Domestic researches mainly focused on soil quality evaluation,with hot topics changing from soil fertility quality to soil pollution,and eventually to soil improvement and restoration.Foreign researches mainly focused on the ecosystem service function of urban green space soil,with hot topics changing from solving urban ecological environment problems to proposing green space maintenance management strategies,and finally to improving urban ecological environment benefits.The research frontiers focused on heavy metal pollution and urban green space ecosystem.[Conclusion]The research focuses of Chinese and English literatures on urban green space soil are different.Chinese literatures pay more attention to the quality of urban green space soil,which is related to national policies,urban development,and ecological environmental protection.English literatures focus more on the urban green space ecosystem,which may be related to climate change,green infrastructure construction,ecological and environmental benefits,etc.[Ch,3 fig.5 tab.58 ref.]
