利用“内蒙古微气象观测蒸发试验”和兰州大学半干旱气候与环境监测站的观测资料,对近地层能量闭合比率异常情况进行了初步分析。结果表明：实际观测的近地层能量近似平衡, EBR频数分布在1附近达到峰值。 EBR异常负值是异常值的主要部分,异常负值和异常正值频次分布均在日出日落及大气弱稳定条件时达到峰值。 EBR异常主要发生在净辐射60,湍流通量?40～40 W/m2,大气处于稳定的情况下。大气湍流结构和地表热通量数值大小不是造成EBR异常的主要原因。

Observation data from a Microclimate and Evaporation Experiment in Inner Mongolia and Semi-Arid Climate Observatory and Laboratory site were used in this paper to analyze the abnormal energy balance ratio in the surface layer. The results show that the observed energy was balanced approximately and the peak value of EBR frequency distribution was around 1. The negative abnormal EBR accounted for the majority of the abnormal EBR, and both the negative abnormal EBR frequency distribution and the positive one reached their peak value in a weak stable condition at sunrise or sunset. EBR behaved abnormally when the net radiation was less than or equal to 0, the turbulent flux was between ?40 and 40 W/m2 and the atmosphere was in a stable condition. The atmospheric turbulent structure and the soil heat flux were not the primary causes of the abnormal EBR.
