摘要

利用河南省鲁山县水保站4a共49次降雨过程资料

分别采用EI30法、CREAMS模型算式、Richardson算式和我国郭新波的修正日雨量模型计算了伏牛山区降雨侵蚀力

以EI30的经典算法作为基准值对3个模型进行了验证

以模型有效系数与相对偏差评价模型的优劣。结果发现

3个日雨量模型的有效系数与相对偏差分别为:0.78±0.55

0.57±0.34

0.45±0.22和0.16~1.27

0.24~1.46

0.40~0.84。验证结果以Creams模型较好

但仍不宜直接使用

应该根据区域降雨特性选择更加合适的参数。

Abstract

Based on 49 single rainfall data from the Lushan County station of soil and water conversation in He'nan Province

various values of rainfall erosivity were calculated using the RUSLE

CREAMS

RICHARDSON and a revised model of daily rainfall amount developed by Guoxinbo

respectively.Results show that model efficients are 0.78±0.55

0.57±0.34

0.45±0.22

respectively.Tested results show CREAMS modol is better than other two models

but it is not appropriate to direct use.The better parameters should be found in future.
