摘要
根据锡林浩特国家气候观象台2007—2009年生长季(5—9月)湍流通量监测资料,对该地区不同天气状况下湍流通量进行了分析,结果表明:CO2通量、动量通量、潜热、显热通量存在明显的日变化规律,变化范围分别在-0.0647～0.0344mg/(m2·s)、0.058～0.207kg/(m·s2)、0.69～95.39W/m2、-31.35～287.2W/m2之间。给出了湍流传输系数Cm=Ch=Cw=6.8×10-3。
According to the National Climate Observatory xilinhaote 2007 to 2009 growing season （from may to September） turbulent flux monitoring data,the area under different weather conditions,the turbulent flux is analyzed,results showed that：CO 2 flux,momentum flux,latent heat,sensible heat flux obvious diurnal variation,changes were in the range-0.0647-0.0344 mg/（m 2 ·s）,0.058-0.207 kg/（m·s 2）,0.69-95.39 W/m 2,-31.35-287.2 W/m 2 between.Turbulent transport coefficient is given C m =C h =C w =6.8×10-3.
