摘要:

2016年是中国现代河流地貌研究的开拓者和奠基人沈玉昌先生100年诞辰,本文对中国河流地貌研究进展进行综述,以资纪念。研究涉及4个方面:① 水系发育与河谷地貌演变,包括大江大河水系历史发育和山区河流地貌;② 侵蚀与产沙过程,包括有物理成因基础的侵蚀产沙模型、侵蚀产沙过程的尺度效应、植被对侵蚀的影响及临界现象、坡面细沟发育过程模拟等;③ 河床过程与河型,包括河道冲淤过程、河床演变、河型成因与演变等;④ 河流地貌系统研究,包括流域系统不同子系统的耦合关系、河流地貌系统中的高含沙水流和多营力地貌过程、河流地貌系统对于自然因素变化和人类活动的响应、河流地貌系统中的泥沙灾害和河流地貌系统的实验研究等。50年前沈玉昌先生与钱宁先生提出在地貌学与河流动力学相结合的基础上发展中国河流学科。文中对此方面的进展进行了综述,并提出了需要深化和解决的问题。

Abstract:

2016 is the 100th anniversary of Professor Shen Yuchang, the founder of river geomorphology in China. To commemorate this event, we reviewed the advances in river geomorphology in China in the past 20 years, which cover the following four topics: (1) river system development and river valley evolution, including the historical development of the Yellow and Yangtze rivers and mountain region river geomorphology; (2) erosion and sediment production processes, including the physically based erosion and sediment yield modeling, scale effect of sediment yield, influence of vegetation on erosion and thresholds, and simulation of hillslope rill development; (3) river channel processes and river patterns, including channel fill and scour behaviors, channel changes and the formative cause of river channel patterns; and (4) study of river geomorphology in the framework of fluvial system, including the couplings between sub-systems, hyperconcentated flows and multiple-agent geomorphologic processes, response of fluvial system to climate change and human activity, sediment-related disasters and the laboratory experiments on fluvial systems. Around 50 years ago, Professors Shen Yuchang and Qian Ning together put forward a strategy for Chinese river researches on the basis of combination of geomorphology with hydrodynamics. In this right direction the river geomorphology in China has achieved an initial breakthrough. In addition, some issues that need to be deepened or solved in the future are addressed.
