The spatial variability of runoff area has a great effect on the time-space input of sediment supply into rivers.
流域产流面积的空间变化对其产沙、供沙的时空输入特性具有制约作用。
Because of the spatial-temporal variability and inhomogeneity of natural factors and the uncertainty of human activities, runoff and sediment yielding is a complicated nonlinear process.
由于自然因素的时空变异性和不均一性以及人类活动的不确定性，因此产流产沙是一个复杂的非线性过程。
