产流及其研究进展

Runoff Generation and Its Research Progress

径流及其形成过程是陆地水文循环的重要环节,而产流是径流形成的首要环节。产流研究在水文学领域具有十分重要的意义,且一直是水文学研究的重要内容。阐述了关于产流的相关概念与内涵,梳理了产流理论的发展历程,剖析了超渗地面径流产流机制、壤中流产流机制、饱和地面径流产流机制、地下径流产流机制等4种基本产流机制的特征、共同规律及其影响因素,探讨了变化环境下产流的研究方法与应用现状,提出了产流研究亟待解决的科学问题。

Runoff and its formation process are important links of terrestrial hydrological cycle,and runoff generation is the primary link of runoff formation.The study of runoff generation is of great significance in the field of hydrology and has been a significant content of hydrology research.This paper expounds the relevant concepts and connotation of runoff generation,and summarizes the development process of runoff generation theory.The characteristics,common rules and influencing factors of four basic runoff generation mechanisms are analyzed,which are hypertonic surface runoff generation mechanism,soil abortion flow mechanism,saturated surface runoff generation mechanism and underground runoff generation mechanism.The research methods and application status of runoff generation in changing environment are discussed,and the scientific problems to be solved urgently are put forward.
