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 .
