Abstract: In order to understand the nylon sand resistance nets for catching sand, the different stacking modes of nylon sand resistance nets were taken. In this study, three stacking modes of high vertical sand barriers were designed, and the stacking positions were designed separately on windward slope and leeward slope as well as at sand resistance nets. The distance between the stacked nylon sand resistance nets and the sand barriers and their length on both windward slope and leeward slope were the same, height of the nets was half of the sand barriers, and the stacked nylon sand resistance nets were higher than the nylon sand barriers. The sand barriers 1.2 m in height were selected to stack, and the stacking distance to the sand barriers was about 45 cm. The results are as follows: ① The depositedsand volume of the different stacking modes of high vertical sand barriers was different, and it was in an order of sand resistance nets>windward slope>leeward slope; ② The depositedsand volume of the three stacking modes was continuously increased with the increase of stacking sand resistance nets; ③ The sand resistance cost of the three stacking modes per unit volume was changed with the increase of stacking sand resistance nets: it was continuously decreased on windward slope and for sand resistance nets and stabilized finally; it was increased at first, then decreased and stabilized finally on leeward slope. The sand resistance cost per unit volume was in an order of resistance sand net
