为了解布袋沙障对风沙流和土壤湿度的影响，通过测定风速和采集地表0~30 cm 输沙，同时对地下0~40 cm 土壤含水率进行测试，分别研究1 m×1 m、2 m×2 m、3 m×3 m 规格布袋沙障防风效能、粗糙度、输沙量和土壤湿度差异。结果表明，布袋沙障能够有效提高0~30 cm 高度范围的防风效能，增加地表粗糙度，显著降低0~30 cm 地表输沙量和改变风沙流结构。3 种布袋沙障的防风效能顺序为1 m×1 m>2 m×2 m>3 m×3 m，1 m×1 m 与其他两种规格布袋沙障的防风效能差异显著（P <0.05），2 m×2 m 和3 m×3 m 规格布袋沙障的防风效能间无显著差异；粗糙度顺序为1 m×1 m>2 m×2 m>3 m×3 m>对照，1 m×1 m、2 m×2 m 和3 m×3 m 规格沙障粗糙度分别比对照高91.31%、78.88%和76.26%，差异极显著（p <0.001）；0~30 cm 输沙量顺序为对照>3 m×3 m>2 m×2 m>1 m×1 m，对照的0~30 cm 输沙量达到了71.43 g/（min·cm2 ），是布袋沙障的32.98 倍，3 种规格布袋沙障与对照沙丘2~10 cm 和0~1 cm 两层沙量的比值λ 均大于1，说明在监测期内地表均处于风蚀状态。土壤含水率顺序为对照>3 m×3 m>2 m×2 m>1 m×1 m，在0~20 cm 土层此变化趋势明显，对照的土壤含水率分别比3 m×3 m、2 m×2 m、1 m×1 m 规格沙障样地的土壤含水率高55.15%、58.63%和67.45%。
