通过对吉兰泰盐湖周边流动沙丘铺设的1 m×1 m、2 m×2 m、3 m×3 m不同规格可降解纤维沙障设置前后沙丘不同部位输沙量、不同高度风速及不同种规格沙障凹曲面深度进行测定，比较分析了风速比、粗糙度、近地表风沙流结构、凹曲面深度与障埂长比值（Z/L）等指标。研究结果表明：在设置可降解纤维沙障后，增加了地表粗糙度，降低了近地表风速；改变了沙丘不同部位近地表风沙流结构，其中沙丘迎风坡下部0~4 cm层的相对含沙量明显大于沙丘中部和上部，特别是0~2 cm层更为显著；与裸沙丘相比，相对输沙量0~4 cm层减少，4~30 cm层增加。通过各规格粗糙度及Z/L值比较表明1 m×1 m规格对粗糙度增大最明显，凹曲面形成最稳定，对风蚀沙埋控制最明显。

By study the different sand location conveying sand amounts ,the different height wind speed and 1 m×1 m,2 m×2 m,3 m×3 m three different standard degradable fiber checkerboard which set up at sand dune .We analyze index such as the wind speed rate ,roughness the wind-sand flow of surface .The depth of concave curved face and the hedge blocker ratio(Z/L).The result of the experiment is apparent after set up the degradable fiber checkerboard. First, the earth’s surface wind speed is weak;second, the earth’s surface is more rough ; third, the earth’s surface wind-sand flow at different location of sand dune alter apparently;last, the relative output of sand at 0~4 cm layer decrease but increase at 4~30 cm layer compare with bare sand dune. At last,1m × 1m checkerboard have great effect on roughness .And concave carved face ,thus, 1 m×1 m sand control hedge is most apparent in control the wind erosion and sand bury.
