中国草地碳研究的发展趋势与特点分析

Development trend and characteristics of grassland carbon research in China

为了解并掌握中国草地碳研究的发展趋势和特点,研究以CNKI(中国知网)数据库为基础,整合3485篇文献,分别对发展趋势、主题词分布、研究层次、学科分布、发文机构、发文作者进行分类汇总,得到初步的结论如下。中国草地碳研究起步较晚,2000年才开始进入活跃阶段,2010年左右初具规模,2013年以后呈波动式增加趋势;草地碳研究焦点集中在有机碳上,且与国家政策紧密相关;草地碳研究学科分布集中在牧畜与动物医学,这与草学(原草业科学)隶属的一级学科直接相关;发文量较大的研究机构和作者主要集中在中国科学院,农科类大学仅有西北农林科技大学和内蒙古农业大学跻身前5。总之,尽管中国草地碳研究近些年得到全面发展,但是仍处于基础或应用基础研究,学科分布和主题词分布过于集中,研究机构和研究者相对比较分散。

In order to understand and master the development trend and characteristics of grassland carbon research in China,3485 literatures were integrated based on CNKI(China National Knowledge Network)database,classified and summarized the development trend,subject word distribution,research level,discipline distribution,publishing institution and author respectively,and reached the preliminary conclusions as follows.Grassland carbon research in China started relatively late.It entered the active stage in 2000,took shape around 2010,and showed a fluctuating uptrend after 2013.Grassland carbon research focuses on organic carbon and is closely related to national policies;The research disciplines of grassland carbon were concentrated in livestock and animal medicine,which was directly related to the first-level discipline of grass science(former prataculture science).Research institutions and authors with a large number of publications were mainly concentrated in the Chinese Academy of Sciences,and only Northwest A&F University and Inner Mongolia Agricultural University are among the top five agricultural universities.In conclusion,despite the comprehensive development of grassland carbon research in China in recent years,it is still in the basic or applied basic research,the distribution of disciplines and subject terms were too concentrated,and the research institutions and researchers were relatively scattered.
