摘要
雨滴高度对色斑直径有一定影响,实验率定色斑直径和雨滴直径的关系为d=0.478D0.610,依此作为研究滤纸色斑法的基础。根据从房县径流实验小区获得的2002—2005年的降雨和径流资料,建立了该地区R指标的最佳组合为E30.I30及R值与降雨量的关系,以月R值=2.766Pi1.151为最好。
It is considered that different heights of raindrop have certain influence on the stain diameter size and, in the experiment, the relation between the stain diameter and the raindrop diameter is d=0. 478D^0.610. This is the research foundation of filter paper stain method. According to the data of rainfall and runoff in Fangxian County of Hubei Province from 2002 to 2005, this paper establishes that the best combination of rainfall erosivity（R） in this area is E30130 and the best relationship between the monthly R value and the rainfall amount is 2. 766pi^1.151.
