摘要
【目的】科学认识河流系统变化过程的滞后响应与累积效应规律,对于正确模拟河流系统的变化过程至关重要。【方法】对河床地貌系统、河流水文系统与河流生态系统变化过程中的滞后响应与累积效应研究成果进行了梳理与总结,并对存在的问题与发展方向进行了分析。【结果】现有研究主要存在以下特点与不足:①对河床演变滞后响应与累积效应研究已成热点,但对作用机制与非线性问题研究不足。②对水文流域汇流的非线性效应研究已有进展,但仍待深入。③对流域植被变化滞后响应研究日益关注,但模型方法与阈值问题有待深化。④模型方法不断完善,但对参数物理意义认识不足等。【结论】未来应从作用机制、非线性效应、阈值问题等方面深化研究,以进一步科学描述河流系统变化过程中的滞后响应与累积效应规律,提升对河流系统变化过程的模拟水平。
【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 insufficient.(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 understanding 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.
