摘要
In this paper we presented a model for calculating CO2 flux in the wheat field based on field simulate test. We adopted crop transpiration as " information picker" of CO2 flux instead of the potential evaporation and crop water stress index. Another crucial factors are leaf area index and air vapor saturation deficit. Experimental coefficient is equal to 1/58. Calculating values have a good agreement with real measurements. The model is useful to estimate regional distribution of CO2 flux.
