| Abstract: | 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. |
