基于文献计量学分析2016年环境土壤学研究热点

本文基于文献计量学方法,结合CiteSpace软件,分析了2016年国内外土壤学及环境科学领域中与土壤有关论文的关键词,揭示了2016年环境土壤学的研究热点和方向,其结果在一定程度上也反映了农业环境科学领域关注的一些重点问题.我们以Soil为关键词,在Web of Science上检索到环境科学和土壤科学SCI论文1 1 747篇.关键词的聚类结果显示2016年的研究热点是“重金属污染与生物累积效应”、“土壤有机污染与生物降解”、“土壤管理与元素循环”、“土壤固碳与全球气候变化”.中国、美国发文量名列前两位,国内中国科学院和西北农林科技大学位列发文量前两位.在CNKI数据库中共检索到2936篇核心期刊论文,关键词共现图谱显示“土壤微生物与环境污染”、“土壤理化性质与水盐运移”、“土壤有机碳与环境效应”、“土壤区域环境与空间变异”为国内期刊论文的主要研究热点.

Research hotspots of environmental soil science in 2016 based on bibliometrics analysis

In the present study, the research hotspots of environmental soil science in 2016 was explored based on the bibliometrics analysis and CiteSpace software. The results also reflected the frontiers in the area of agricultural environment to a certain extent. When soil was selected as the key word, we collected 11 747 SCI papers included on "Web of Science" on soil science and environmental science in 2016. The clustering results of key words in 11 747 papers showed that the main research hotspots were "heavy metal pollution and bioaccumulation effects", "soil organic pollution and biodegradation", "soil management and the recycling of elements", and "soil carbon sequestration and climate change". China and USA were the top two countries contributing to these papers, while Chinese Academy of Sciences and Northwest Agriculture & Forestry University were the top two institutions in China. And also 2936 papers were collected when we chose soil as the key word in CNKI, the clustering data showed that the main research hotspots in CNKI were "soil microbial and environmental pollution", "soil physicochemical properties and the movement of water and salts", "soil organic carbon and environmental effect", and "soil regional environment and spatial variation".
