中文摘要：
蒸散发是大气和水文循环的重要环节之一。影响水面蒸发的因素以温度、风速为主，但三者之间的关系式尚未明确。在海河流域北京市大兴区境内，设计了一个风速对水面蒸发影响的原位对比观测实验，在2010年观测实验结果的基础上，进一步探究了温度与风速对水面蒸发影响的耦舍效应机理。分析了研究区域试验期间．辐射、湿度、降雨、气温、风速、蒸发的特性和规律，利用SPSS软件推导了试验期间研究区域蒸发与温度、风速的关系式，对解释“蒸发悖反”具有实证意义，也为流域水文模拟提供了参数支持。
英文摘要：
Evaporation is one of the important links of atmospheric and hydrological circulation. The major influentlal tactors ot water evaporation are temperature and wind velocity, however, the relationship among them is not clear. In -situ observation experiment of the influence of wind velocity on evaporation is designed in Daxing District, Beijing City, located in Haihe River Basin. On the basis of the experiment in 2010, the coupling effect mechanism of influence of temperature and wind velocity on evaporation is further researched. The characteristics and laws of radiation, humidity, precipitation, temperature, wind velocity and evaporation in the study area are analyzed. The relationship expression of temperature, wind velocity and evaporation is obtained by using SPSS. The result provides demonstration for explaining ＂ evaporation paradox＂.
