摘　　要：研制了搭载超声风速仪的六旋翼无人机测风系统,对热带海岛地区近海岸、农业温室基地以及密集建筑群等典型地貌开展风场实测.结果表明:地面粗糙度指数、摩擦速度和地面粗糙度长度均随场地粗糙度增大而提高.近海岸风剖面可采用指数律或对数律模型,与我国规范A类、欧洲规范Ⅰ类地貌值均吻合较好,湍流强度明显小于现有规范值;温室基地风剖面符合指数律模型,风剖面和湍流强度与日本规范Ⅲ类地貌值吻合较好;密集建筑群风剖面符合指数律模型,且与美国规范B类地貌值吻合较好,湍流强度与日本规范Ⅳ类地貌值吻合较好.该研究验证了无人机测风的可靠性,为海岛地区工程结构的抗风设计奠定基础,也为复杂地貌的风场观测、风环境评估与风能资源利用提供了新方法.A wind measurement system of a six-rotor unmanned aerial vehicle(UAV)equipped with an ultra⁃sonic anemometer was developed and was used to carry out the wind field measurement on typical landforms such as coastal areas,agricultural greenhouse bases and dense building areas in tropical island areas.The results show that the ground roughness index,friction velocity,and ground roughness length all increase with the increase of field roughness.The wind profile of the coastal areas can adopt the exponential law or logarithmic law model,which is in good agree with the specified values of the landform in the Chinese Standard A and European StandardⅠ,and the turbulence intensity is significantly smaller than the existing standard value;the wind profile of the greenhouse base conforms to the exponential law model,in which the wind profile and turbulence intensity are in good agreement with the specified values of the landforms in the Japanese standard TypeⅢ;the wind profile of dense building areas conforms to the exponential law model,in which the wind profile is in good agreement with the specified values of land⁃forms in the American standard Type B and the turbulence intensity is in good agreement with the specified values of landforms in the Japanese standard TypeⅣ.This research verifies the reliability of the wind measurement system of a six-rotor UAV,lays the foundation for the wind resistance design of engineering structures in island areas,and provides a new method for wind field observation,wind environment assessment,and wind energy resource utiliza⁃tion in complex landforms.
