英文摘要	A 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.
