摘要:
泥沙搬运是小流域土壤侵蚀、搬运和沉积过程中一个很重要子过程,搬运能力的定量研究是刻画土壤侵蚀过程和建立物理过程侵蚀模型的理论基础.对于目前被广泛采用的坡面漫流输移方程和沟道挟沙水流方程的试验条件进行了比较分析,探讨了其在黄土高原地区侵蚀模拟过程中的应用可能性和局限性.同时,表述了在黄土高原地区选择搬运能力方程需要考虑修正条件的必要性.
Abstract:
Sediment transportation is an important sub-process of soil erosion-transport-deposition process in a small watershed.Quanititative analysis on sediment transport is a strong basis for depicting soil erosion process and constructing process-based soil erosion model.Comparison of widely used sediment transportation of overland flow and channel flow has been done.The suitability and limitation of equation application in soil erosion process on the Loess Plateau was discussed.For applying sediment transportation equation on the Loess Plateau the parameter modification is very necessary.
