Abstract: Blownsand land in Houtian region consists of sand dunes, sandy blownouts, undulated sand sheet, vegetated sand mound and sandy river terraces. As a rule, sandy river terraces contain more than 76.4% of sand, with the top layer reaching up to 87.78%, therefore, they can not only provide abundant sand sources but also serve as a potential blownsand land. In this paper the moisture conditions and chemical properties, of sandy river terraces were analysed, this greatly contributes to a better understanding of the differentiation of water, nutrients and trace elements when the potential sandy land turned into serious blowusand land.
