Being based on the runoff plot investigations, a dynamic model of grey systems about the rainfall, the runoff rate and the soilerosion was introduced by using the grey systems theory.
根据一些径流小区的试验资料，运用灰色系统理论，建立降雨量、径流量、土壤侵蚀灰色系统动态模型。

But the amount of soilerosion or runoff rate was unsignificantly related with the mean rainfall rate in each plot.
