- 探讨黄土丘陵区新的侵蚀环境背景下小流域侵蚀泥沙的再分布特征,为开展和研究小流域土壤侵蚀及产沙过程提供理论依据。以黄土丘陵区典型淤地坝为研究对象,基于分形理论,通过分析淤地坝沉积泥沙垂直剖面的泥沙粒径组成变化及分形特征,研究了小流域坝前沉积泥沙再分布特征。结果显示:小流域坝地沉积泥沙剖面粒径由上到下依次呈现细—粗的周期分布规律,粗细分布的厚度差异较大,但整体上沉积层厚度随着沉积时间显著降低;沉积泥沙粒径以粗粉粒为主,平均百分含量为51.73%,且坝地剖面各分层的分形维数分布范围介于2.60～2.78; 沉积泥沙粗化度变化范围介于0.04～0.37,平均值为0.16。研究表明随着退耕时间的增加,小流域沉积泥沙厚度显著降低,侵蚀泥沙的细颗粒物质含量增加。
- Abstract:
- In order to provide the theoretical basis for the study of soil erosion and sediment yield in small watershed, the characteristics of sediment redistribution under the new erosion background were discussed.In this paper,special dam on the loess hilly area was taken as an example,the fractal dimension was applied to analyze the variation of grain size composition and fractal characteristics of sediment,and study the characteristics of sediment redistribution.The results show that:from top to bottom,the grain size of sediment profile in small watershed presents the periodic distribution law of fine-coarse,and the thickness of sediment layer varies greatly and decreases with the deposition time; the silt is the main coarse particle size,average percentage content of coarse particle is 51.73%;the fractal dimension distribution of each layer in the section of the dam is between 2.60 and 2.78;the coarseness of sediment varies from 0.04 to 0.37 with an average value of 0.16.The sediment thickness decreases and the amount of fine particulate matter in sediment increases in small watershed with the deposition time.
