The case study shows that SP model is convenient and effective, and that SP model can be applied to mid and long term prediction of many runoff processes.

实例研究的结果说明，SP模型简便、实用性强，可在径流中长期预测中广泛应用。

Based on the stochastic hydrology simulation theory and techniques, a stochastic mathematical model which can reproduce the statistic characteristics of observed yearly runoff processes is studied.

本文用水文随机模拟的理论和方法，探求符合实测统计特性的全年径流过程的随机数学模型。

Agricultural non-point pollution is formed by 4 processes of rainfall runoff, soil erosion, surface solution stripping and soil solution seepage.

农业非点源污染主要由降雨径流、土壤侵蚀、地表溶质溶出和土壤溶质渗漏4个过程形成。
