infiltration flow principally depended on the presence of macropores. With increasing degree of

degradation, soil macropores quickly changed to mesopores or micropores. The proportion of

total infiltration flow through macropores and mesopores significantly decreased with the most

substantial decrease observed for the macropores in the 0-10. cm soil layer. The substantial

decrease of macropores caused a cut in soil moisture and hydraulic conductivity. This study

improves the understanding and prediction of alpine meadow soil and ecosystem changes and

provides guidelines for improving water flow modeling under the background of global climate
