利用榆中县2011年10月2-15日外场实验的湍流观测资料,结合天气背景,对比分析了城市同一区域内不同下垫面的动量通量、感热通量、潜热通量和CO2通量的差异特征.结果表明：草地下垫面和混凝土下垫面之间动量通量的差异较小；混凝土下垫面的感热通量整体大于草地下垫面,且在日间差异较大,差异的最大值达109.29 W/m2；草地下垫面的潜热通量在日间明显大于混凝土下垫面,差异的最大值达153.8 W/m2,夜间两下垫面潜热通量差异较小；CO2通量在排放源附近较大.

With the turbulence observational data from the field experiment in Yuzhong County from October 2, 2011 to October 15, 2011, a contrastive analysis was made of the changing features of the momentum flux, the sensible heat flux, the latent heat flux and the CO2 flux in different underlying surfaces of the same area in a city by combining it with an analysis of the weather background. The results indicated that the difference in the momentum flux between the grassland underlying surface and the concrete underlying surface was relatively small;the sensible heat flux of the concrete underlying surface was greater than that of the grassland underlying surface, and it showed a large difference during the daytime;the maximum of the difference was 109.29 W/m2. The latent heat flux of the grassland underlying surface was obviously greater than that of the concrete underlying surface during the daytime, and the maximum of the difference was 153.8 W/m2. During the night, the difference between the two underlying surfaces was relatively small and the CO2 flux was comparatively large near the emission source.
