摘要: The widespread construction of photovoltaic (PV) power stations within northwest China poses an environmental threat because severe wind erosion and land degradation attributed to unique control issues caused by the stations. In this study, various engineering (E), plant (V), biocrust (B) treatments were evaluated for their effectiveness in reduction erosion. placement solar panels with wide inlets narrow outlets velocity reductions at inlet that sharply increased outlet formed distinct zones deflation, direct shear abrasion (DSA), deposition. reduced velocities sand transport rates, comparison E4 (DSA zone + a gravel/deposition red clay) being most effective 87% total rate. Both V1 (Sedum aizoon L.) V2 (Pennisetum alopecuroides (L.) Spreng) aerodynamic roughness, decreased rates erosion-deposition budget under or between panels. Treatment B2 (moss crust) rate control. All had effects on reducing erosion, we strongly recommend use moss crust, gravel mulch, clay mulch deflation zones, DSA deposition respectively, these PV located sandy areas.
