%X Based on the analysis of sensitivity of analytical footprint models of an eddy covariance system(EC) and a Large Aperture Scintillometer(LAS),as well as the observation of EC and LAS at Miyun flux station of Beijing(from August 2006 to December 2007),the flux spatial representativeness of EC and LAS were preliminarily analyzed.The results are as follows:(1)The source areas of EC and LAS are sensitive to wind direction,Monin-Obukhov length,aerodynamic roughness length and measurement height.(2)The source are...
