中文摘要：

采用自制雨滴发生器产生雨滴,选取野牛草、狗尾巴草、苜蓿草和玉米小苗4种草本植物及6种茎高进行溅蚀实验,采用色斑法计算雨滴直径,系统研究草本植物对雨滴动能的影响作用。结果表明：（1）在相同植物茎高的条件下,草本植物的叶面积越大,经其作用后雨滴改变直径也越大,两者呈现明显的正相关关系;（2）在同种草本植物的条件下,雨滴直径与植物茎高呈正相关,这一关系可以用幂函数表示;（3）草本植物的茎高和叶面积均和雨滴动能呈正相关关系。其中在相同草本植物的条件下,植物茎高和植物改变后的雨滴动能符合与植物叶面积相关的线性函数;（4）溅蚀量（S）和雨滴动能（E）呈正相关,符合与植物叶面积相关的线性函数,且线性方程的斜率随叶面积的增大而减小。

英文摘要：

Selecting four kinds of herbaceous plants, six plants stem height for raindrop with ten replicated experiments was conducted to explore the influence of herbaceous plant on raindrop kinetic energy. Results showed that： （1）The raindrop diameter increased with the increase of plant leaf area under the same plant stem height. （2）The raindrop diameter increased with the increase of plant stem height under the same type of herbaceous plant. This relationship could use a power function to describe. （3）The raindrop kinetic energy increased with the increase of plant leaf area and plant stem height. The raindrop kinetic energy linearly increased with plant stem height under the same type of herbaceous plant. （4）The splash amount linearly increased with the raindrop kinetic energy, and the slope decreased with the increase of leaf area.
