利用2001-2009年冬季四川省二郎山观冰站的覆冰资料和气象资料，在明确影响导线覆冰因子及建立覆冰模型理论框架的基础上，分析了覆冰厚度与若干气象因子的联系，结果发现覆冰增长与水汽压、风速等单一气象指标之间的相关并不理想；尝试用若干气象指标综合咸水汽输送量指标，该指标与覆冰增长率有较显著的相关。在此基础上建立了一个以风速、温度、水汽压等常规气象观测要素为参数的导线覆冰模型，将综合覆冰拟合的冰厚与实测冰厚值进行比较，拟合结果较好地模拟了实际覆冰，达到工程应用的目的。

By using the daily icing data of ice station and the related station data of Erlangshan Mountains in Sichuan Province in winter of 2001-2009 ,relationships between the icing thickness and some meteorological factors are analyzed based on the identified conductor icing factors and the con-structed icing theory model. It is found that the icing increase is not well related to an individual meteor-ological factor, for example, vapor pressure and wind speed. An attempt to define water vapor transport index combined with some meteorological factors is employed and the index couples closely with the ic-ing increase ratio. Finally, a conductor icing model is built according to the parameters of conventional meteorological observations including wind speed, temperature and vapor pressure. Comparison of the comprehensive fitting ice cover thickness with the observed one shows that the better fitting results can be achieved to serve project applications.
