摘　　要：为研究三峡库区水面蒸发的变化规律,基于2013年8月至2022年7月三峡库区巴东水文站水面蒸发及气象数据,利用灰色关联度和偏相关系数分析了蒸发与气象因子(气温、水汽压、蒸发池内水温、风速、日照等)的相关度,采用5种不同的蒸发模型(通用公式、李万义修正模型、回归模型、BP和ELM神经网络)定量解析不同气象要素对蒸发趋势的贡献。结果表明:研究期内巴东站各蒸发模型拟合效果较好,模型构建准确,分别分析各个模型率定期和检验期的精度后,确定最适合巴东站蒸发计算模型为李万义修正模型。In order to study the transformation law of evaporation from water surface in the Three Gorges Reservoir area,the water surface evaporation data and meteorological data of Badong Hydrological Station from August 2013 to July 2022 were used.The correlation between evaporation and meteorological factors such as air temperature,water vapor pressure,water temperature in evaporation pool,wind speed and sunshine were analyzed by grey correlation degree and partial correlation coefficient.The contribution of different meteorological factors to evaporation trend were quantitatively analyzed by five evaporation models(General formula,Liwanyi modified model,regression model,BP and ELM neural network).The results showed that the evaporation models of Badong Hydrological Station had good fitting effect and accurate model construction during the study period.After analyzing the fitting of the rate period and test period respectively,it was showed that the most suitable evaporation calculation model for Badong Hydrological Station is Liwanyi modified model.
