坡面土壤侵蚀响应机制及其水动力学特征研究进展

Research Progress on Response Mechanism of Slope Soil Erosion and Its Hydrodynamic Characteristics

坡面是土壤侵蚀的主要发生区。概述了坡面土壤侵蚀发生与土壤性质、降雨、植被、地形、水土保持措施等指标间的响应机制和坡面水动力学参数及机理研究进展;分析表明,坡面土壤侵蚀是一个十分复杂的过程,不仅受土壤内部因素如土壤均质程度、土壤质地、土壤含水量等的影响,还与外部条件如降雨、植被、地形、水土保持工程等紧密相关。但是,现行的土壤侵蚀研究体系并不完善,需要对土壤侵蚀各影响因素之间的相互作用关系和动力学物理机制进一步明确和深入认知。

Slope is the main area of soil erosion.This paper summarizes the response mechanism between the occurrence of slope soil erosion and soil properties,rainfall,vegetation,topography,water and soil conservation measures,and the re-search progress of slope hydrodynamics parameters and mechanism.The analysis shows that the slope soil erosion is a very complex process,which is not only affected by internal factors such as soil homogeneity,soil texture,soil moisture content,but also closely related to external conditions such as rainfall,vegetation,topography,and soil and water conservation projects.At present,the current research system of soil erosion is not perfect,the interaction relationship and dynamic physi-cal mechanism between the various factors of soil erosion need to be further clarified and deeply understood.
