摘  要：
掌握国内光伏治沙模式及其效应，可为光伏电场在沙漠区生态治理应用提供参考。通过对宁夏和内蒙古沙漠地区的光伏电场的风蚀和风积情况进行实地调查，分析风沙危害模式。结果表明：光伏板前后区域发生风蚀和堆积过程，在光伏板下和板间形成风蚀坑(沟)和积沙堆(带),光伏板聚风增加了光伏电场风险程度，风沙流对光伏板也有磨蚀危害。光伏电场的光伏板起到“风障”和“沙障”的作用，覆盖地表和调控地面蚀(积)程度，可降低风速，减少输沙量。光伏电场组件及其阵列耦合可进一步提高其防风固沙效能，光伏治沙已成为风沙灾害治理的新途径。

摘  要：
Grasping the domestic photovoltaic sand control mode and its effects,can provide reference for the appli-cation of photovoltaic electric fields in desert ecological control.By conducting field investigation into the wind ero-sion and deposition conditions of photovoltaic electric fields in the desert areas of Ningxia and Inner Mongolia,the wind-sand hazard patterns were analyzed.The results showed that the wind erosion and deposition process occurred in the front and rear areas of the photovoltaic panels,and the wind erosion pits(ditches)and sand accumulation piles(belts)are formed under and between the photovoltaic panels.The wind accumulation of the photovoltaic panel in-creased the risk of the photovoltaic electric field,and the wind-sand flow also had abrasion effects on the photovoltaic panels.The photovoltaic panels of the photovoltaic electric field played the role of"wind barrier"and"sand barrier",covering the surface and regulating the degree of ground erosion(accumulation),which could reduce the wind speed and reduce the amount of sand transport.The coupling of photovoltaic power station components and their arrays could further improve their wind prevention and sand fixation efficiency.Photovoltaic sand control has become a new way to control wind-sand disasters.
