土壤一维垂直入渗过程的类型与特性研究

以大量的大田土壤水分入渗试验资料为依据，分析了农业生产周期内耕作土壤一维垂直入渗过程的类型、特性及各自的成因，并对照实际生产过程分析了各类型入渗过程对应的土壤条件。结果表明，在以年为周期的农业生产期间，大田土壤入渗过程大致分为3种类型，即：肥胖型、渐变型和扁平型；不同类型的入渗过程与不同的农业生产阶段和土壤理化条件相对...

Types and Features of Vertical One Dimensional Soil Infiltration Processes

Based on the infiltration experiments of field soils,the types,features and causes of vertical one dimensional infiltration processes of cultivated soil were analyzed and each type of infiltration process corresponding soil conditions were studied by referencing to the actual production process.The results show that: during agricultural production cycle,the infiltration process of field soil can be roughly divided into three types: obese,graded and flat;different types of infiltration process are corresponding to different agricultural production phases and physicochemical conditions in soil.In different agricultural production stages,surface soil structure,macroporosity quantity and permeability result in the changes of hydraulic conductivity,which lead to different infiltration processes and types.
