Macropores properties of forest soil and its influence on water effluent in the upper reaches of Minjiang River
岷江上游森林土壤大孔隙特征及其对水分出流速率的影响

Macropore structure in forest soils is very important to soil subsurface water flow. In the soil layer thinning region, large amounts of water can breakthrough the macropores and form underground runoff after rain. As a result, storm peak flow is decreased, the ratio of surface water and underground water is changed, and river water fluctuation more slowly and remains more stable. Although there are many methods to be used to research soil macropores, macropores radii measurements by different methods are o...
