摘　　要：黄土高原是我国典型的生态环境脆弱区,2/3面积处于干旱半干旱地区,水循环过程是该区域物质循环的核心。土壤水力参数(饱和导水率和水分特征曲线)是研究水循环过程的重要参数,其直接测量要浪费大量的人力、物力和财力,传递函数为其快速获取提供了有效途径。本研究系统分析了目前黄土高原已建立的土壤水力参数传递函数,传递函数建立的方法及不同传递函数输入变量的尺度依赖性,指出了当前研究存在的不足,指出了未来黄土高原水力参数传递函数的研究方向,以期为黄土高原水力参数传递函数的发展提供参考。The Loess Plateau is a typical region with fragile ecological environment in China,with two-thirds of its area located in arid and semi-arid zones.The water cycle process is the core of material cycling in this region.Soil hydraulic parameters,including saturated hydraulic conductivity and the soil water characteristic curve,are crucial for studying the water cycle process.However,direct measurement of these parameters can be extremely costly in terms of labor,materials,and finances.Pedotransfer functions provide an effective means for their rapid acquisition.This study systematically analyzed the existing pedotransfer functions for soil hydraulic parameters established on the Loess Plateau,the methods used to establish these functions,and the scale dependence of different input variables in these functions.The deficiencies in current research and proposes directions for future research on pedotransfer functions for soil hydraulic parameters on the Loess Plateau are indicated.The aim is to provide a reference for the development of transfer functions for soil hydraulic parameters on the Loess Plateau.
