2.The characteristics of grain size parameters of modern coastal aeolian sands are the basic problems of coastal aeolian sand research. This paper, taking the temperate coastal zone in China as an example, makes use of the grain size parameter such as component of grain size, mean size, standard deviation, skewnss and kurtosis to study the characteristics of grain size parameters of modern coastal aeolian sands on the basis of data of 136 grain size samples.
