国内土壤盐渍化研究现状解读——基于CNKI数据库文献计量分析

Interpretation of domestic soil salinization research status——Bibliometric analysis based on CNKI database

近些年来,国内专家学者致力于土壤盐渍化的理论与实践研究,并取得了丰硕的成果。本文选取CNKI数据库为数据来源,就国内土壤盐渍化研究进行文献计量分析。结果表明:早期国内土壤盐渍化研究多集中在对成因和防治的分析研究上,之后聚焦土壤盐渍化监测与预测,近些年主要关注其改良和未来发展热点。通过高频关键词分析,当前国内土壤盐渍化研究的内容是极其广泛,涉及多学科多领域,但也存在诸多不足和局限性,应在发展的背景下,进一步完善现有研究内容和方法,并给予该领域更多的关注。

In recent years,domestic experts and scholars are committed to the theory and practice of soil salinization research,and has achieved fruitful results.In this paper,the CNKI database was selected as the data source for the bibliometric analysis of domestic soil salinization research.The results showed that,the early research on soil salinization in China mainly focused on the analysis and research on the causes and prevention,then focused on the monitoring and prediction of soil salinization,and then focused on its improvement and future development.Based on the analysis of high-frequency keywords,the current research on soil salinization in China is extremely extensive,involving multiple disciplines and fields.However,there are also many shortcomings and limitations.It is necessary to further improve the existing research contents and methods under the background of development,and pay more attention to this field.
