摘要/Abstract

摘要： 土壤水力参数的选取和确定是土壤中水分运动和污染物迁移预测的基础.本文在国内外研究成果的基础上,综述了土壤水力参数的模型(土壤水分特征曲线模型、土壤导水率模型)及其直接测定法和间接推求法,并比较了土壤水力参数的模型及确定方法的适用性与局限性,以便为生态环境建设和农业可持续发展研究中土壤水力参数的选取提供依据.

关键词: 土壤水分特征, 土壤导水率, 土壤水力参数, 模型

Abstract: The selection and determination of soil hydraulic parameters is the basis of predicting water movement and solute transfer in soils. Based on the researches at home and abroad, the models of hydraulic parameters, including those of soil water characteristic curve and soil hydraulic conductivity, and their direct and indirect measurement methods were reviewed, and their application and limitation were compared to provide evidence for the selection and determination of soil hydraulic parameters in the study of ecological environment construction and sustainable agriculture development.

Key words: Soil hydraulic parameters, Model, Soil water characteristic, Soil hydraulic conductivity
