摘要黑土是一種腐殖質層厚,質地鬆散,肥力很高,孔隙比較大而透水性差,粘粒含量高,適于耕作的淋溶土。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 acidic liquid related to decomposition of organic mater during hydrocarbon enrichment in the late diagenesis, and m eteoric - waters during epidiagenesis, had resulted in dissolution of detrital feldspars and carbonate cements, which contributed a better retention of reservoir quality for the sandstones
溶蝕作用是砂巖物性改善的主要原因,尤其是晚期成巖階段,在富含有機酸和無機酸酸性孔隙流體的作用下形成一定量的次生溶蝕孔,使儲層砂巖物性得到一定改善;在表生成巖階段,由於大氣降水的介入,儲層物性再次得以改善。With increase of artificial forest age, the content of soil organic matter decreased sharply. and soil physical, chemical and biological properties of forest became worsen. from soil physical properties analysis, soil silt, clay, physical clay, aggregate degree and structure coefficient in topsoil increased with increase of artificial forest age and soil sand deceased
