【摘要】：土壤转换函数是利用一定数量的土壤样本及其实测数据,在土壤理化性质和水力参数之间连接起来建立函数关系,由此推求土壤水力性质的间接方法之一,应用十分广泛.本文基于国内外土壤转换函数的构建应用发展情况,讨论土壤转换函数特征,分析转换函数类型、预测变量、构建方法、参数估算等,总结各种土壤转换函数的优点和不足,说明国内外常用的转换函数及其预测变量,提出构建、应用和验证转换函数的数据要求,为土壤转换函数构建、正确应用及其适用性分析提供科学参考.
[Abstract]:Soil conversion function is one of the indirect methods to calculate soil hydraulic properties by using a certain number of soil samples and its measured data to establish a functional relationship between soil physical and chemical properties and hydraulic parameters. Based on the development of the construction and application of soil conversion function at home and abroad, this paper discusses the characteristics of soil conversion function, analyzes the types of conversion function, predictive variables, construction methods, parameter estimation, and summarizes the advantages and disadvantages of various soil conversion functions. The data requirements for the construction, application and verification of conversion functions are presented, which provide a scientific reference for the construction, correct application and applicability analysis of soil conversion functions.
