在世界沙漠中格状沙丘比较常见 ,但研究程度很低 .腾格里沙漠东南缘格状沙丘由NE SW向主梁和与其近乎垂直的副梁构成 .对沙丘区域气流、表面气流、沉积物粒度特征和内部沉积构造等方面的研究表明 ,格状沙丘的主梁形成于主风———西北风的作用 ,而副梁则是在主梁基础上并由主风和次风———东北风的交替作用下形成的 ,其形态 动力学类型应属纵向沙丘置于横向沙丘之上的一种复杂型沙丘 . Lattice-shaped sand dunes in the world desert are relatively common, but the degree of research is very low.The latitudinal sand dunes in the southeast margin of the Tengger Desert consist of NE SW to the main girder and its nearly vertical sub-girders.For dune area air currents, surface air currents, sediments Grain size characteristics and internal sedimentary structures and other aspects of the study shows that the main form of the sand dune lattice formed in the main wind --- the role of the northwest wind, while the sub-beam is based on the main beam and the main wind and the secondary wind --- The formation of the northeast wind alternating role, the type of dynamic form should be vertical dune placed in the horizontal dune above a complex sand dune.
