黄石地区降雨侵蚀力指标R值的研究

Study on Rainfall Erosivity Index-R in Huangshi Areas

水土流失是目前世界面临的几大生态环境问题之一。收集了详细的降雨强度、雨量动能和土壤流失量,得到每场降雨侵蚀力因子值,运用数理统计的方法,对所采集的土壤流失量与该次采样所对应的降雨侵蚀力因子建立回归方程,通过分析确定通用方程中降雨侵蚀力因子的最佳计算模式。

Soil and water loss is one of the environmental problems which we are confronted with.The pa- per is written to determine each rainfall erosivity factor by a detailed collection of rainfall intensity,rainfall kinetic energy and the soil loss.A regression equation,with which a best calculation method concerning rainfall erosivity factors will be determined in the universal equation,shall be established with mathemati- cal statistics to express the relationship of the loss of soil tested and the rainfall erosivity factors.
