  1. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 )耕作制下紫色土的產流主要機制是: 1 )當前土壤含水量未達到飽和狀態,表面產流起始間有明顯滯后現象,這與紫色土的快吸水性和較多非毛管孔隙密切相關;當前土壤較乾燥,初期強較大,易形成臨相對不透水表層,表面產流峰也有明顯滯后現象。 2 )表面徑流的產流方式主要是產流,當土壤達到飽和狀態后,有四川大學博士學位論文小部分回歸流發生,但主要是飽和產流發生,因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 )壤中流主要是飽和產流,與過程有明顯的滯后,而且停后的壤中流產流特徵無關。
