摘　　要：水面蒸发敏感因素的判断,对于干旱区水资源的规划与利用具有重要指导意义。文章以新疆塔里木河下游铁干里克气象站2005年资料为例,对研究区水面蒸发影响因素进行分析。采用熵值法对水面蒸发进行敏感性分析,并与关联分析法分析结果进行对比。结果表明:在塔里木河下游铁干里克地区,温度与风速二因素对水面蒸发影响最为敏感;基于熵值法的敏感因素研究结果与关联分析的结果基本一致。The judgment on sensitive factors to water surface evaporation is very important for water resources planning and utilization in arid areas. In this paper, using meteorological data of Tieganlike in 2005, the sensitive factors which affect water surface evaporation in freezing period and non-freezing period was studied. First, the sensitivity of each factor were analyzed with the entropy value method; secondly, using relational analysis the results was verified. The results show that temperature and wind speed were the most sensitive factors; the results of entropy value method and relational analysis method were the same, especially for the major distinguishing factors.usly larger than that in northern Xinjiang during summer to autumn, particularly in autumn.
