通过对影响土壤渗透的多个因素的测定,研究了石质山地不同土壤不同层次的渗透能力,不同水温对渗透的影响,渗透筒不同插入深度对渗透的影响,由此可以得出,土壤的渗透能力是由各立地条件的土壤理化性质决定的。影响土壤入渗性能的最主要因素是土壤的总孔隙度和非毛管孔隙,这与土壤容重和土壤含水量也有很大关系。入渗与水温表现为较好的线性关系。
Through the determination of many factors influencing soil infiltration, the effects of infiltration capacity and water temperature on the infiltration of different soil layers in different stratum and the infiltration depth of permeable tube were studied. It can be concluded that the soil Permeability is determined by the physical and chemical properties of the soil at each site. The most important factor influencing soil infiltration is soil total porosity and non-capillary porosity, which is also related to soil bulk density and soil water content. Infiltration and water temperature showed a good linear relationship.
