植物根系影响土壤水分运动研究的文献计量分析

An Analysis of the Influence of Plant Roots on Soil Water Movement Based on Bibliometric Studies

近年来,植物根系影响土壤水分运动的问题得到广泛关注,相关研究发展迅速已渐渐成为土壤学、水文学、水环境与水灾害等学科交叉研究的热点。本文从植物根系影响土壤水分运动入手,整理2000~2022年Web of Science核心合集与CNKI数据库中相关文献,计252篇,分析国内外相关研究发文现状、研究热点区域和关键词;进而围绕国内相关研究的两个热点区域(西北干旱区和西南湿润区),综述植物根系特征影响土壤水分运动研究现状与发展趋势。主要结果有:①近20来,国际和国内相关研究逐渐增多,但整体上发文量依然相对较少,Journal of Hydrology期刊成为该研究领域热门国际期刊;②国内外相关研究热点存在差异。国际期刊相关研究侧重于方法和过程研究,中文期刊相关研究则偏向于根系特征研究;③西北干旱区和西南湿润区是国内相关研究的两大热点区域,本文对上述两个地区植物根系特征及其影响土壤水分运动机制进行了分析与评述,未来相关研究应加强其研究方法和技术手段等方面的创新与发展。

In recent years,the influence of plant roots on soil water movement has received extensive attention,and the related researches have developed rapidly and gradually become a hot spot in the interdisciplinary research of soil science,hydrology,water environment and water disasters.Starting with the effect of plant roots on soil water movement,this paper analyzed the current situation,hot areas and keywords of relevant research papers at home and abroad by collating 252 relevant literatures in the Core Collection of Web of Science and CNKI database from 2000 to 2022.Then,the research status and development trend of the influence of plant root characteristics on soil water movement were reviewed based on the two domestic hot spots(northwest arid area and southwest humid area).①In the past 20 years,the number of relevant international and domestic research publications has shown a gradual increase trend,but the overall number of publications is still relatively small.Journal of Hydrology is the most popular international journal in this research field.②There are differences in relevant research hotspots at home and abroad.The research focuses on methods and processes in international journals,while the keywords in Chinese journals tend to root characteristics.③The arid region in northwest China and the humid region in southwest China are the hot areas of related research in China.This paper analyzed and reviewed the mechanism of plant roots affecting soil water movement in the two regions.The innovation and development of research methods and techniques should be strengthened in the future.
