The results showed that hop-pocket sand barrier can improve the wind-break potency of 0-30 cm height range effectively, increasing the sand dune surface roughness, reducing the sediment discharge of 0-30 cm height range significantly. The order of wind-break potency of hop-pocket sand barrier was 1 m×1 m>2 m×2 m>3 m×3 m. The difference of 1 m×1 m was significant compared to 2 m× 2 m and 3 m×3 m, and there was no significant difference between 2 m×2 m and 3 m×3 m. The order of surface roughness was 1 m× 1 m>2 m×2 m>3 m×3 m>CK; the roughness of 1 m×1 m, 2 m×2 m and 3 m×3 m were increased by 91.31%, 78.88% and 76.26% higher than the control and the differences were significant (P<0.001). 0-30 cm sediment discharge of the control reached 71.43 g/(min·cm²), and it was 32.98 times more than hop-pocket sand barrier.λ eigenvalues was the sediment discharge ratio of 2-10 cm and 0-1 cm of hop-pocket sand barrier and the control, and λ >1, deducing that their surfaces were wind eroded during the monitoring period. The order of soil moisture was CK>3 m×3 m>2 m×2 m>1 m×1 m, the trend of 0-20 cm layer was obvious, and soil moisture of the control was increased by 55.10%, 58.63% and 67.45% higher than 3 m×3 m、2 m×2 m and 1 m×1 m hop-pocket sand barrier., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=xiKXPZRjma3yJvS+GBrsgQ==, pdfFileSize=1609788, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
