| 摘 要： | 本研究以永定河河滩流动沙地为对象,通过对永定河河滩流动沙地及周边稀疏草地的风沙流活动、粗糙度、沙丘运移等的定位与半定位试验观测,对永定河河滩流动沙地的风沙流活动规律进行研究,并对该地区风沙流活动的影响因子进行了分析。结果表明,河滩地下垫面风沙流特征存在显著的差异,下垫面覆盖物不同时地表粗糙度也不同。

| Abstract: | This research had been carried out in hirst drifting sand land of Yongding river.The speciality of sand-drift activity in hirst drifting sand land of Yongding river has been conducted based on the fixed-position and the half-fixed position observation on the migration of wind-sand,roughness,migration of dune in hirst drifting sand land of Yongding river and its surrounding sparse wild grass land.At the same time,the influencing factors on sand-drift activity in hirst drifting sand land of Yongding river has been analyzed in this paper.The result shows that the character of sandy stream with different in different vegetation and roughness conditions. |
