| 摘 要： | 利用康山、棠荫、都昌、星子、湖口水文、气象资料,应用器测折算法和气候模式法,确定鄱阳湖1955—2004年年、月水面蒸发量,并对近50 a的水面蒸发变化特征进行了分析,对影响水面蒸发的温度、湿度、风速等主要因子的变化进行了模拟计算。结果表明,除5月外的各月蒸发量及年蒸发量均呈减少趋势,湖区气温升高、湿度增大是造成水面蒸发减少的根本原因,与温室效应密切相关,是对大范围气候变化的同步响应。

| Abstract: | According to hydro-meteorological data of Kangshan, Tangyi n, Duchang, Xingzi and Hukou, using the instrument-conversion method and climate model method, the yearly and monthly water surface evaporations of the Poyang Lake during 1955-2004 are calculated. The variation trend of Poyang Lake surface evaporation in recent 50 years is analyzed and the variations of temperature, humidity and wind speed that influence water surface evaporation mostly are stimulated. The results show that the water surface evaporations decreased in recent 50 years due to the increases of air temperature and humidity,which are closely related to the greenhouse gas. |
