| 摘 要： | 坡面细沟形态是一个降雨驱动下侵蚀产沙的微地形动态响应系统,这一地形因素体现着坡面侵蚀动力学各要素及其相互作用,是基于物理过程的水蚀预报模型的关键部分。要建立具有物理意义的坡面侵蚀产流产沙预报模型,就必须从地形角度对细沟形态及其演化过程进行深入研究。评述了近年来国内外在坡面细沟形态演变与量化领域的相关研究成果,从理论研究和观测方法两方面剖析了制约研究发展的因素,提出了推动该研究发展的对策,即:构建细沟形态量化参数评价标准,从建立"状态+时间"综合量化模式入手,以坡面细沟形态为切入点,研究一个连续降雨过程中细沟形态的发育过程与降雨侵蚀产沙过程的关系,定量揭示坡面侵蚀响应规律。

Advances in morphological evolution and quantitative study of rill on hillslope |

| Abstract: | Morphological processes of rill at hill slope cause a dynamic response system with soil erosion driven by rainfall.The Geomorphology is caused by the erosion factors and their interactions,which is the key part of the runoff process based erosion model.To establish a physical meaning prediction model of the runoff and sediment erosion,it is necessary to conduct further study of rill morphology and its evolution process based on geomorphology.This paper reviews the advances in morphological evolution and quantitative study of rill on hill slop.Factors used in this review restrict to two aspects of theoretical and observational method.Countermeasures to promote the research development are suggested to construct the evaluation standard of rill morphological characteristic parameters,to establish comprehensive quantitative model as'state + time',to take the rill morphology as the breakthrough point,to study the relationship between rill evolution and erosion development in a continuous rainfall process,and then to reveal the response law of slope erosion. |
