Energy balance and latent heat flux partition in wheat field

Based on the Bowen Ratio-Energy Balance Method (BREB),the paper analyzes the variational characteristic of the energy balance components and the latent enrgy partition in the winter wheat field after the wheat regreen.The soil moisture content and leaf area index (LAI) are the critical factors in energy partition process. Besides,the variation of evaporation from soil as related to leaf area index has also been calculated and analyzed.
