植物生物力学特性在水土保持领域的研究进展与热点

Research Progress and Hotspots of Biomechanical Properties of Plants in Relation to Soil and Water Conservation

[目的]植物生物力学特性是水土保持植物措施研究的重要内容,在固土保水,阻流拦沙等方面发挥着重要作用。利用CNKI和Web of Science数据库检索植物生物力学特性相关文献,分析植物生物力学特性在水土保持研究领域的进展和未来发展趋势。[方法]通过Citespace和VOSviewe软件对年发表论文数、热点期刊、主要研究国家、主要研究作者、关键词等进行可视化展示。[结果]1990—2010年植物生物力学特性在水土保持领域研究的发文量较少,2010年以后,国内和国外的发文量都出现明显增长。在国际上,美国发表论文数位居首位,中国发文量位居世界第二,但研究成果的国际影响力还有待提升。国内形成了以胡夏嵩、格日乐、刘静、陈丽华为首的4大研究团队,国际上目前尚未形成权威的大型团队。[结论]国内研究主要聚焦于沙漠植物和坡面植物生物力学特性分析,侧重于植物生物力学特性对其防风抗蚀作用的影响,国际上对坡面植物根系加筋作用、沙漠先锋植物防风抗蚀作用、水生植物的衰减波浪的作用均进行了研究,研究内容更加多元化。

[Objective]Biomechanical properties of plants are an important part of studies dealing with the use of plants for soil and water conservation because of the important role plants play in soil stabilization,water conservation,and water flow and sediment retention.The objective of this paper was to search the CNKI and Web of Science databases to find literature related to plant biomechanical properties in order to highlight the current status and development trend of biomechanical properties of plants related to soil and water conservation.[Methods]Citespace and VOSviewer were used to visualize the annual number of published papers,highly cited journals,primary research countries,primary research authors,keywords,etc.[Results]The number of publications on the biomechanical properties plants in the field of soil and water conservation was low during 1990—2010.After 2010,there was a significant increase in the number of both domestic and foreign publications.The United States ranked first in the number of papers published;China ranked third in the number of papers published.The international influence of research results needs to be improved.Four major research teams led by Hu Xiasong,Ge Rile,Liu Jing,and Chen Lihua have been formed domestically,but no authoritative large team has been formed internationally.[Conclusion]Domestic research has mainly focused on the analysis of biomechanical properties of desert plants and slope plants,placing emphasis on the influence of plant biomechanical properties on windbreak and soil-fixing effects.International research has been more diversified,with studies conducted on the role of root reinforcement of slopes,the windbreak and erosion resistance role of desert pioneer plants,and the role of aquatic plants in wave attenuation.
