摘要：根据在沙漠化程度十分严峻的乌兰布和沙漠实际所测得的有关流动、半固定和固定沙丘风沙运动的相关数据,运用多元统计分析的方法分别建立了3种沙丘的输沙率函数模型,定量地分析了输沙率与风速及高度的相关关系,并对风沙流结构进行了相应研究。这对于指导我国的沙漠化治理工作具有重要的建设性意义。
The sandy desertification is serious in Ulanbuhe desert. Based on the observed data about the sand movement by wind in the fixed dune, the semi-fixeddune and the moving dune, the determinant models of the sand-transporting ratio were constructed respectively for the three types of dunes by the multivariate statistical analysis method. The relationship between the sand-transporting ratio and wind velocity or height were quantitatively analyzed; and the structure of aeolian sand was also examined. Research results from our analysis will provide constructive suggestions for the sandy desertification control in China.
