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 )耕作制下紫色土的产流主要机制是: 1 )当雨前土壤含水量未达到饱和状态时,表面产流起始时间有明显滞后现象,这与紫色土的快吸水性和较多非毛管孔隙密切相关;当雨前土壤较干燥,降雨初期雨强较大时,易形成临时相对不透水表层,表面产流峰也有明显滞后现象。 2 )表面径流的产流方式主要是超渗产流,当土壤达到饱和状态后,有四川大学博士学位论文小部分回归流发生,但主要是饱和超渗产流发生,因为紫色土的相对不透水层和其它透水障碍层不明显。 3 )壤中流主要是饱和产流,与降雨过程有明显的滞后,而且雨停后的壤中流产流历时与降雨特征无关。
