【摘要】 在系统分析了淳化县泥河沟及彬县、黄龙、永寿、耀县和西峰１９６４～１９９５年部分径流小区试验资料、降水自记资料４９７组的基础上，运用数理统计方法，得出了黄土高原南部坡耕地土壤侵蚀预报的基本方程，并根据理论推导得出径流量方程式，通过量纲分析和实测数据资料验证后，建立了规整均匀坡面上的土壤侵蚀预报动力模型，为该区域土壤侵蚀预报的进一步研究奠定了基础。更多还原

【Abstract】 Based on systematically analysing the runoff plot data of Nihegou in Chunhua,Binxian,Huanglong,Yongshou,Yaoxian and Xifeng from 1964 to 1995 and 497 precipitation data,the basic prediction equation of slope cultivated land in south loess plateau was obtained using statistical method,the runoff energy equation was proposed according to theoretical reasoning,through dimension analysis and measured data test,the kinetic model of soil erosion prediction of homogeneous slope area has been established.This kinetic model lay a foundation for further studies on soil erosion in this area.更多还原
