which are carried out at site scene in floating desert area of northwest edge region in the line of mountain Guma-Shaya of Tarim Basin in Northwest Taklimakan Desert. Four kinds of shape of sand windbreak walls are used in experiment. There are straight-line type?semi-circle type? triangle type and M-word type respectively. The process of sand ripple forming and moving has been observed and tested when using different shape of sand windbreak. At the same time
the contrast analysis is conducted
and this will provide experimental basis for the computational and numerical simulation in the future.
