基于CiteSpace的城市群生态安全研究发展态势分析

基于CiteSpace软件,以CNKI与WOS数据库中2003—2017年645篇城市群生态安全相关文献为研究对象,对国内外城市群生态安全研究现状及发展态势进行分析。研究发现,近15年来国内外城市群生态安全研究呈波动上升态势,2008年后国内学者在国外期刊发文量、文献及作者被引频次逐年增高;国外历年城市群生态安全研究网络离散,关键词中心度较低,突现词单一;国内研究网络完整,前沿分支较少,且尚未构建完整的研究体系框架,其中"可持续发展"突现频率最高、"生态安全"突现时间持续性久、"PSR模型"是最新突现词频;国内"城市生态安全格局"与国外"污染与增长"等是城市群生态安全的研究热点。总体来看,城市群生态安全研究更加强调多学科与多角度开展理论基础研究,注重内部机理与外部构建协同作用,静态与动态测度相结合进行生系统安全评价与分析,不断趋向网络化治理和生态安全治理等研究将成为未来重点关注的方向与角度。

Ananalysis of ecological security of the urban agglomeration development trend based on CiteSpace econometric analysis

Based on the CiteSpace econometric analysis visualization software, 645 papers related to the ecological security of urban agglomeration published in the years 2003-2017 and found in the CNKI(China National Knowledge Infrastructure) and WOS(Web of Science) databases were taken as study objects to research the development status and situation of urban agglomeration ecological security at home and abroad. It was found that the amount of research on ecological security of urban agglomeration at home and abroad has been fluctuating in the past fifteen years. Since 2008, domestic scholars have increased the number of theses, documents, and authors'' citation frequencies in foreign periodicals year by year. The international research on ecological security of urban agglomeration was dispersed over the past years; there were few very common key words. Domestically, the research network was complete but lacked cutting-edge branches, and had no complete framework for a research system. "Sustainable development" had the highest emergence frequency, "ecological security" had the longest duration, and "PSR model" was the most recent frequently used term. The terms "urban ecological security pattern" domestically and "pollution and growth" abroad were the research hotspots for ecological security of urban agglomeration. On the whole, the research on ecological security of urban agglomeration emphasizes multidisciplinary and multi-angle theoretical basic research. It focuses on the synergy of internal mechanisms and external construction and the combination of static and dynamic measures to evaluate and analyze the safety of the system, thus constantly moving towards network and ecological security management may become the key direction and angle in the future.
