摘要
以湖北省在建的孝 -襄高速公路为依托 ,根据沿线边坡不同土质土壤建立试验小区和自记雨量观测站 ,对广泛应用于坡耕地土壤流失量预测的美国通用土壤流失方程中的主要因子降雨侵蚀力因子 R和土壤可蚀性因子 K进行修正 ,使其适用于高速公路建设扰动土壤流失量预测 .给出了雨侵蚀力指标 R和土壤可蚀性因子 K的计算式 .
Several experimental standardized spots for soil loss collection were set up on side slopes of Xiaogan-Xiangfan freeway under construction, and an on-the-spot auto-recorder of rainfall was installed as well. Data collected were for revision of main parameters R(rainfall and runoff) and K(erodibility of soil) of the Universal Soil Loss Equation(USLE) which was widely applied to forecast of soil loss quantity of ploughland so as to predict the soil loss quantities of different sorts of soil on side slopes disturbed by engineering treatment. It concluded that the optimal parameter representation for R and K.
