中文摘要：

基于世界粮农组织、汤森路透公司Webof Science等公开数据库，系统分析了2000年以来全球茶（Camellia sinensis）与咖啡（Coffea arabicaL）的生产和研究情况。结果表明，2000--2013年，累计产茶与咖啡最多的国家分别是中国（总量的29．1％）和巴西（总量的30．6％）。2011年至2015年茶与咖啡的研究论文数量年增长率分别是4．3％与5．6％。美国茶与咖啡的研究论文无论总量还是质量上为最高，自2011年起中国的年产论文量已超过关国；茶与咖啡研究领域呈现出多学科交叉的特性：热点研究领域是生物化学、营养学以及与医学交叉的学科。

英文摘要：

In this study, the production and research activities in tea （Camellia sinensis） and coffee （Coffea arabica and C. canephora L） in the world were analyzed based on the public accessible data collected since 2000. The results indicated that China and Brazil were the biggest producers for tea （29.1% of total） and coffee （30.6%）, respectively. The numbers of totally published research articles for tea and coffee over the period of 2000 - 2015 were 31764 and 13974, respectively with a yearly increase of 4.3% on tea and 5.6% on coffee. USA dominated the research on both tea and coffee in terms of number and impact of the published articles. However, the research articles on tea from China have been outnumbered USA since 2011. Interdisciplinary research activities turned to be a developmental trend and research articles focusing on biochemistry, nutrition, health promotion are getting more and more attention.
