摘　　要：利用2001年夏季的内蒙古东部流动沙丘地区大气边界层试验资料,采用空气动力学方法和涡动相关法计算动量通量、感热通量等湍流通量;分析了非平坦下垫面风速、温度廓线结构对湍流通量获取结果的影响和通量廓线关系的适用性;对比了空气动力学方法和涡动相关法获取湍流通量结果。同时,结合流动沙丘可移动、含水量多等地形和气候特征,讨论了非均匀下垫面下湍流通量获取方法。Utilizing the test data of atmospheric boundary layer in the moving dune of Inner - Mongolia in the summer of 2001, the paper calculated the turbulent flux including the momentum and sensible heat flux by the aerodynamics method and eddy covariance method, analyzing the effects of nonuniform underlaying surface and temperature profile structure on turbulent flux and adaptability of flux - gradient relationship, and compared with results of acquiring turbulent flux by aerodynamics method and eddy eovariance method. Meanwhile, combined with the terrain and climatic characteristics of moving and sufficient water content , discussing the acquiring method of turbulent under the nonuniform underlaying surface.
