用波文比-能量平衡法(BREB)分析了冬小麦返青后麦田能量平衡和潜热分配的变化特征及影响因素。在平衡过程中,土壤含水量和叶面积指数(LAI)是决定能量分配的关键因素。并分析了返青后土壤蒸发随叶面积指数变化的规律。
The characteristics of the energy balance and the distribution of latent heat of wheat field after turning green with winter wheat were analyzed by the method of BREB and the influencing factors. In equilibrium, soil moisture content and leaf area index (LAI) are the key determinants of energy allocation. The law of soil evaporation with leaf area index after turning green was analyzed.
