英文摘要	Solar energy parks in desert areas must resist the encroachment of moving sand and burial by migrating dunes. It is therefore important to design economical, effective sand fences to protect the parks. Based on an analysis of wind regime data and the grain-size distribution of transported sands, field-measured sand fluxes, and theoretical calculations, we designed the form, height, and structure of such sand fences. The aeolian sand in the study area is uniformly graded fine sand with particles ranging in size from 0.063 to 0.250 mm. Drift potential averaged 646 VU (i.e., a high-energy wind environment) and dune migration averaged 11.9 m yr(-1). The vertical mass flux profiles of aeolian sand followed power functions. The sand quantity transported below 10 cm in height accounted for > 99.8% of the total, with most of the remainder transported above 20 cm. The yearly maximum depth of sand deposited at the sand fences ranged from 1.63 to 2.50 m for mobile dunes and from 0.84 to 1.08 m for flat land. The lateral pressure exerted on the sand fence by accumulated sand ranged from 4.9 to 9.2 kPa for mobile dunes and from 1.1 to 3.1 kPa for flat land. Our results suggest an optimal sand fence height of 2.0 to 2.5 m for areas with mobile dunes and 1.0 to 1.5 m for flat land. To conserve materials, the sand fence could be combined with a security fence or wind fence. Our results provide a reference for designing sand fences in sandy areas.
