摘要: 截留是植被对降水的第1次再分配,是重要的水文要素之一。目前,大多数植被截留的研究都是以乔木和灌木为主,关于草冠截留的研究还是相对欠缺。笔者针对目前草坪草冠层截留研究的现状和所存在的问题,从草冠截留的主要影响因素(降雨量、降雨强度、叶面积或叶面积指数等)以及现有草冠截留量测定方法和装置2个方面论述了草冠截留的研究进展。分析表明:草被植物的截留影响因素研究主要是以降雨条件、叶面积指数和草被盖度,以及草被植物本身特征为重点,各因素的综合交互作用影响研究非常缺乏;测定方法在精确度和适用范围上也有待提高。

Abstract: Rainfall interception was the first redistribution of rainfall and was also one of the important hydrological elements. At present, arbor trees are the main object of the researches on vegetation interception, while studies on lawn grass canopy interception are few. In view of the present situation and the problems about the turf grass canopy interception, the paper reviewed the research progress of grass canopy interception from two aspects: main factors (the amount of rainfall, rainfall intensity, leaf area or leaf area index etc.) affecting the grass canopy interception and the methods for determination of grass canopy interception and device. Analysis showed that: the influencing factors of grass grown interception was mainly based on the condition of rainfall, leaf area index and grass coverage, as well as the grass characteristics, while studies on the effect of comprehensive interaction between each factor were few; accuracy and applicability of method for the determination were largely limited .
