摘要
径流和泥沙研究一直是国内外水文学界研究的重点。文章分析了降雨、森林植被、地形因素、人类活动、地质和土壤因素对径流和泥沙的影响。阐述了水文学中的尺度分析和尺度转换,提出了不同尺度下影响径流泥沙的主导影响因子。
The study on the nmoff and sediment is always the key point of hydrologic field at home and abroad. The impact of rainfall, forest vegetation, topography, human activities, geological and soil factors on the nmoff and sediment are analyzed, and scale analysis and scale transformation in hydrology are elaborated. As a result, the dominant factors influencing the runoff and sediment under different scales are presented.
