2 )耕作制下紫色土的產流主要機制是: 1 )當雨前土壤含水量未達到飽和狀態時,表面產流起始時間有明顯滯后現象,這與紫色土的快吸水性和較多非毛管孔隙密切相關;當雨前土壤較乾燥,降雨初期雨強較大時,易形成臨時相對不透水表層,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超滲產流,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,但主要是飽和超滲產流發生,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,與降雨過程有明顯的滯后,而且雨停后的壤中流產流歷時與降雨特徵無關。The low resistivity oil layers include those layers with high salinity formation water, high water saturation and low oil saturation, or riched in argilliferous sandstone low resistivity oil layers
