河流系统变化过程滞后响应与累积效应研究述评
A Review of Delayed Response and Accumulation Effect in Variation Process of River System
摘要
Abstract
[Objective]Scientifically understanding the patterns of delayed response and accumulation effect in the variation process of river systems is important for correctly simulating the process.[Methods]In this paper,existing research on the delayed response and accumulation effect in the variation process of riverbed geomorphology system,river hydrological system,and river ecosystem is reviewed and summarized,and existing problems and development directions are analyzed.[Results]Existing studies exhibit the following characteristics and limitations:(1)research on the delayed response and accumulation effect of riverbed evolution has become a hotspot,but studies on the mechanism of action and nonlinear effects remain insuffi-cient.(2)Progress has been made in research on the nonlinear effects of watershed confluence,but further investigation is still needed.(3)The delayed response of watershed vegetation changes has received increasing attention,but the modeling methods and threshold issues require deeper exploration.(4)While modeling methods are continually improving,the under-standing of the physical meaning of parameters is limited.[Conclusion]Future research should be deepened in areas such as the mechanism of action,nonlinear effects,and threshold issues.This will enable a more scientific description of the delayed response and accumulation effect patterns in the variation process of river systems and improve the simulation level for this process.关键词
