Using turbulent data during observational period in 2009 at Namco Monitoring and Research Station for Multisphere Interactions, Chinese Academy of Sciences (NAMORS/CAS) and footprint model, the quantity of turbulence data and the contribution of the inhomogeneous underling surface for the turbulence flux was analyzed. The obtained results show that the distribution of the turbulence flux was uniform due to the different  land uses. The contribution of grass for the turbulence flux was largest in whole year. For the varying atmospheric stability stratification, the contribution of the turbulence flux was different around 200 m surrounding the station. Upwind of the tower were high flux contribution and high quality of the turbulence flux. Under the unstable and neutral stratification condition, the data quality was higher than it under stable surface layer at night. The low quality of the turbulence flux was under the stable stratification. The quantity of the turbulence flux was influenced by land-lake wind and atmospheric stability stratification on this area.
