The purpose of this study which is discussed about grain size, grain density, grain water content, wind velocity and Aeolian sand at Yuanli coastally. In this paper, the Aeolian sand flux is catch by sand sampler, and wind velocity data which is measure by multi-layer anemometer. Meanwhile, this paper of examination that use regression analysis to discuss the Aeolian sand factor in influence. The results of regression analysis that can be derived by line expression between wind velocity and Aeolian sand, the grain size, grain density have negative relationship with Aeolian sand. However, the grain water content have no relationship with Aeolian sand at 0.3% water content. in addition to estimates of Aeolian sand flux by π Theorem which is: **: significance 1% *: significance 5%
