AbstractA model for calculating CO2 flux in the wheat field and an algorithm fnr estimating CO2 flux in the regional scale were presented using the remote sensing data and supplementary micro-meteorological data. First of all a-longer-term measurement was carried out during winter wheat growing period in Yucheng Experimental Station using the spectro-radiometer system, the thermal infrared radiometer system, the Bowen-ratio device as well as the eddy-correlation device. Two kinds of issues concerning remote sensing and CO2 flux can be obtained. Based on the observations a remote sensing, model was established. Then when a the NOAA-AVHRR passed over the experimental area simultaneous measurements were carried nut with the satellites. A regional distribution image for CO2 flux over wheat canopy in North China (500 x 500 km(3)) was made using the supplementary ground data and NOAA-AVHRR remote kenning data which was calibrated bi the synchronous observation. The sources and sinks for CO2 fluxes in the region can be seen obviously.
