生态足迹研究的时空分布与演进分析

Spatiotemporal Distribution and Evolution Analysis of Ecological Footprint Research

生态足迹是衡量可持续发展的有效方法。为更全面了解国内外生态足迹研究进展,基于文献计量与知识图谱方法,以909篇中国知网数据库(CSSCI)和1951篇Web of science核心合集收录期刊数据为研究对象,从国内外生态足迹研究时空分布特征、研究热点及演进趋势方面展开对比分析。研究发现:国内外发文量趋势不同。中文发文量呈倒“U”形曲线,外文发文量呈指数级增长趋势,全球范围内美国发文量最多,中国位居第二;国内外均未形成核心作者群。学科交叉性较强。发文量最大的外文期刊为Ecological Indicators,其他植物、环境、生态学、毒理学、经济学等跨领域的期刊突出了国际生态足迹研究的综合性与交叉性。国内外研究侧重点不同。国内外在可持续发展评估、足迹家族、经济环境关系等方面研究具有相似性,国内研究表明了中国的生态文明政策导向和经济发展阶段特点。最后,认为未来生态足迹研究可能侧重于生态足迹与气候变化耦合、行业或地区的生态承载力/压力、可再生能源的生态效应等方面。

Ecological footprint is an effective way to measure sustainable development.To fully understand research progress of ecological footprint at home and abroad,based on the bibliometrics and knowledge map methods,the journal data collected by Chinese CNKI Database(909 CSSCI articles)and Web of Science Core Collection(1951 articles)were taken as the research object.The temporal and spatial distribution characteristics,research hotspots and evolution trends of ecological footprint research at home and abroad were compared and analyzed.The results show that publication trend between domestic and foreign is different.The number of Chinese articles shows an inverted“U”curve,while foreign papers have an exponential growth trend.The United States publishes the most papers globally,and China ranks second,but there is no core author group at home and abroad.Disciplines are cross-cut and comprehensive.The most widely published foreign language journal is Ecological Indicators.Other interdisciplinary journals on plants,environment,ecology,toxicology and economics highlight the comprehensiveness and intersections of international ecological footprint research.Research focus at home and abroad is different.Domestic and foreign studies are similar in sustainable development assessment,footprint family,economic-environmental relationship,etc.Domestic research shows the characteristics of China's ecological civilization policy orientation and economic development stage.Finally,it's considered that the future ecological footprint research may focus on the nexus of ecological footprint and climate change,ecological carrying capacity/pressure of industries or regions,and ecological effects of renewable energy.
