O článku:
The Loess Plateau is the main source of water in Yellow River, China. After 1980s, the Yellow river water
presented a significant reduction, what caused the decrease of the Yellow river discharge had been debated in academic
circles. We proceeded with runoff generation mechanisms to explain this phenomenon. We built saturation excess runoff
and infiltration excess runoff generation mechanisms for rainfall–runoff simulation in Jingle sub-basin of Fen River
basin on the Loess Plateau, to reveal the influence of land use change on flood processes and studied the changes of
model parameters under different underlying conditions. The results showed that the runoff generation mechanism was
mainly infiltration-excess overland flow, but the flood events of saturation-excess overland flow had an increasing trend
because of land use cover change (the increase of forestland and grassland areas and the reduction of cultivated land).
Some of the model parameters had physical significances,such as water storage capacity (WM), infiltration capacity (f),
evapotranspiration (CKE), soil permeability coefficient (k) and index of storage capacity distribution curve (n) showed
increasing trends, and index of infiltration capacity distribution curve (m) showed a decreasing trend. The above results
proved the changes of runoff generation mechanism from the perspective of model parameters in Jingle sub-basin, which
can provide a new perspective for understanding the discharge reduction in the Yellow River basin.
