铅与健康研究地域和年龄分布文献计量分析

目的：本研究通过对1996—2007年间国内外铅与健康关系的研究文献进行文献计量学分析,了解国际铅与健康的研究地域分布,以及研究对象的年龄分布,为今后的铅与健康关系的研究工作提供一些思路和依据。方法：本研究以中国生物医学数据库、MEDLINE数据库为数据源,检索1996—2007年间国内外公开发表的铅与健康关系的研究文献,采用定量分析法,进行文献量年代研究,撰文合作度研究,各国文献分布研究、国内省区文献分布研究、研究对象年龄分布描述等。结果：铅与健康关系研究的国内外文献量均呈明显波动上升趋势,我国撰文合作度低于国外同期水平。世界主要研究国家为美国、英国等。广东等省区为我国主要研究省区。国内外对铅与儿童健康研究的文献均较多。结论：全球铅与健康关系的整体研究处于波动增长阶段,美国是全球铅与健康关系研究的科学活动中心,全球科研分布不平衡性较为突出。广东是全国的科学活动中心,主要产出地分布在东部经济较发达地区及中部科研实力较强的地区。我国铅与健康关系的研究还未形成规模化和合作化的趋势。国内铅与健康关系的学科研究呈现出应用发展阶段,国外研究处于相对成熟稳定阶段,研究重点均为儿童铅中毒,并更加关注低龄铅中毒。

Discussion on the Functions of the Administrative Commission of High and New Bibliometric Analysis on the Regional and Age Distribution of the Research on Lead and Health

Objectives：A bibliometric analysis on the literatures studying the relationship between Lead and health published in China and foreign countries in the period of 1996-2007 is conducted for understanding the regional and age distribution of the research on Lead and health and providing some bases and ideas for the future research.Methods：The study takes ＂China Biomedical Literature on Disc＂ and ＂MEDLINE＂ as the data sources to search the literatures about Lead and health published during 1996-2007 in China and foreign countries,and adopts the quantitative analysis to study the each year＇s publication volume of the literature,the authors＇ cooperation,the distribution of each country＇s literature,the distribution of each province＇s literature in China,and the age distribution of research objects.Results：The volume of domestic and foreign literatures about Lead and health shows a clear fluctuations rising trend,and the authors＇ cooperation is lower than that of other countries in the same period.The main research countries include United States,Britain and others,and the main research provinces in China are Guangdong and others.The volume of literatures researching Lead and children＇s health published in China and abroad is more.Conclusions：The global research on the relationship between Lead and health is in a fluctuations growing stage.United States is the Lead and health research centre in the world,the imbalance of the global scientific research is more serious.Guangdong Province is the Lead and health research centre in China.The main output places of the literature about Lead and health in China are distributed almost in the eastern economically developed region or central region with stronger scientific research strength.And the scale and cooperative trend is still not formed in China.The research in China is in the application development state at present,and the research abroad is in the relatively mature and stable stage.The study emphases of China and foreign countries are children＇s Lead poisoning,especially focusing on underage Lead poisoning.
