摘　　要：生态化学计量学已经成为国内外生态学研究的热点问题.作为一门新兴学科,科技文献能够反映科学研究的发展动态和热点变化.以Web of Science数据库为数据源,利用专业数据分析工具TDA(Thomson Data Analyzer)和Ucinet工具,对所有年份生态化学计量学研究相关的论文进行计量挖掘分析.结果表明:2000年以来发文量呈现直线上升趋势,且发文量较多的期刊多集中在一区、二区期刊;研究涉及多个学科领域,主要集中在环境科学与生态学、海洋与淡水生物两个学科方向.美国、德国、中国、加拿大等国家在生态化学计量学开展的研究最多,美国的亚利桑那州立大学、中国的中科院是开展研究最多的机构.国际该领域的研究热点集中在不同营养级、植物不同部位(如叶片)之间的碳、氮、磷的计量关系以及植物个体生长发育、种群增长、群落生态和生态过程的联系,尤其是对森林、草地和湿地生态系统的植物、土壤的元素计量特征.Ecological stoichiometry has become a research hotspot in the ecology research area. As an emerging discipline,science and technology literature can reflect the development of scientific research and hot spots.Choosing the Web of Science database as the data sources,the professional data analysis tools,such as the TDA（Thomson Data Analyzer）and the Ucinet tool,were used for measure mining analysis on the papers about ecological stoichiometry for all years. The results show that the number of published papers has linearly increased since 2000 and the journals which have published more relevant papers concentrated in the journals in areas one and two. The researches involve multiple disciplines,mainly concentrating in environmental sciences and ecology,marine and freshwater organisms. The United States,Germany,China,Canada and other countries have published many papers in ecological stoichiometry study. Arizona State University and Chinese Academy of Sciences are the major research institutions. The international research hotspot is nowfocused on the measurement relationship of carbon,nitrogen,phosphorus at different trophic levels,and element content of different parts of plant（such as leave）and plant growth,development of individuals,population growth,community ecology and ecological processes,especially the metrological characteristics of forest,grassland and wetland ecosystem of plants and soil elements.
