中国风沙物理研究50a(Ⅱ)

Research Achievements in Aeolian Physics in China for Last Five Decades(Ⅱ)

1998年初中国科学院知识创新工程得到了国家的批准,在建设国家创新体系的战略背景下,风沙物理研究得到了新的发展机遇。为了适应国家创新体系的要求,风沙物理学首先重新凝练了学科方向和目标,改善研究手段、拓展研究内容、创新研究思路,使我国风沙物理学研究的国际影响不断增加。笔者从风沙颗粒运动、风沙流、风沙边界层、风沙地貌动力学、土壤风蚀、防沙工程原理和风沙电等几个方面比较全面地回顾了中国科学院知识创新工程实施以来,我国风沙物理学研究所取得的主要成就。

The Knowledge Innovation Project of the Chinese Academy of Sciences was approved in the early 1998, which provided the study of aeolian physics with new opportunity. To meet the requirements of the knowledge innovation system, the things of the first importance was to re-concise the research direction, improve research facilities, extend research contents. After six years efforts, the aeolian research in China is getting more and more recognized by scientists around the world. This paper summarizes the latest research achievements in such seven aspects that include sand particle movement, lowing sand cloud, blowing sand boundary layer, dynamics of aeolian landforms, soil wind erosion, the principles of blowing sand control and electrification of wind-blown sands.
