Windblown sand hazards seriously threaten the safe operation of highways in desert areas. Reasonable risk assessment can provide the basis for windblown sand hazards prevention and risk reduction. To facilitate the formulation of better windblown sand hazards prevention and reduction strategies, a new windblown sand hazards risk assessment model along the highways was proposed, in which seven evaluation indicators were selected from danger of the hazard-causing factors, vulnerability of the hazard-forming environment, and the vulnerability of the hazard-bearing body. The model was established based on the combination weighting method of game theory, and the risk map was generated based on the GIS platform. Finally, the model was applied to the windblown sand hazards risk assessment along the Wuhai-Maqin Highway. The result showed that the risk of the windblown sand hazards along the Wuhai-Maqin Highway is mainly medium, low, and very low. High and very high risk windblown sand hazards sections account for only 33% of the total length of the highway. The high and very high risk highway sections of the windblown sand hazards are mainly distributed in the hinterland of shifting dunes area and near the horizontal curve with a small radius in the flat sandy land area. By comparing with the real information of windblown sand hazards along the highway, correlation was up to 85.93%, which verified the accuracy of the model. The model can be applied to windblown sand hazards risk assessment along the highways.

风沙灾害严重威胁沙漠地区公路的安全运营。合理的风险评估可为风沙灾害的防治与减灾工作提供依据。为助力制定更完善的风沙灾害防治与减灾策略，本研究提出一种适用于公路沿线的风沙灾害风险评估模型，该模型从致灾因子危险性、孕灾环境脆弱性以及承灾体脆弱性三个维度选取了7项评价指标。本模型基于博弈论组合赋权法构建，并依托地理信息系统（GIS）平台生成风险分布图。最后，将该模型应用于乌玛高速公路（Wuhai-Maqin Highway）沿线的风沙灾害风险评估。评估结果显示，乌玛高速公路沿线的风沙灾害风险以中等、较低和极低风险为主。高风险与极高风险的风沙灾害路段仅占公路总里程的33%。此类高、极高风险路段主要分布于流动沙丘腹地以及平沙地内的小半径平曲线路段附近。通过与公路沿线风沙灾害的实际监测信息对比，模型相关性高达85.93%，验证了该模型的准确性。该模型可应用于公路沿线的风沙灾害风险评估工作。
