中国镉污染研究现状的文献计量学分析

A Bibliometrical Analysis of Status on Cadmium Pollution in China

摘要: 采用文献计量学的方法，在《中国学术期刊网络出版总库》中，以“镉污染”作为关键词，检索了中国学者在国内期刊上发表的中文文献，并对镉污染领域年代分布、文献被引用频数及下载量、期刊分布、研究机构、核心作者、学科领域、研究领域及基金资助进行统计分析。结果表明：我国镉污染研究起步较晚，近40年从年代发文量分布显示，镉污染研究整体呈上升的趋势；每篇文献平均被引用9.34次，每篇文献平均被下载239.87次；文献刊登分布较为分散，农业环境科学学报、安徽农业科学和生态环境学报是刊登镉污染文献最重要的组成部分和发表阵地，迫切需要一种镉污染研究的专业期刊；研究单位也较为分散，主要集中在高等院校；镉污染研究涉及的学科颇多，但主要集中在“环境科学与资源利用”学科；土壤是镉污染最严重的，修复材料主要集中在植物和微生物；国家自然科学基金是镉污染研究最重要的基金；镉污染研究领域将进入一个全新的发展阶段。本研究具有一定的影响力，研究极具代表性，可为我国镉污染领域的研究提供参考价值。

Abstract: We adopted a bibliometrical approach to evaluate the status of cadmium pollution research in “China CNKI database”, with “cadmium pollution” as keywords, searching the Chinese literatures published in domestic journals, China scholars, and the distribution of cadmium pollution in the field of literature cited and downloading frequency, journal distribution, research institutions, core author, subject areas, funding research and fund statistics analysis. The results showed that cadmium pollution research in China started late, nearly 40 years from publication in the distri-bution of cadmium pollution, the overall upward trend; each literature cited 9.34 times the average; the average of each document was downloaded 239.87 times; published literature distribution is more dispersed; agricultural environment science journal, journal of agricultural science and ecological environment in Anhui are the most important parts of the cadmium pollution published literature and published positions; it urgently needs a professional journal of cadmium pollution; research units are more dispersed, mainly concentrated in the institutions of higher learning; a lot of research involved cadmium pollution, but mainly concentrated in the “environmental science and resource utilization”. Soil is the most serious cadmium pollution. Restoration materials are mainly focused on plants and microbes. The National Natural Science Foundation is the most important fund for cadmium pollution research, and cadmium pollution research will enter a new stage of development. This study has a certain influence, and the research is very representative, which can provide reference value for the research in the field of cadmium pollution in China.
