摘　　要：将辽宁省近30年全部观冰站的覆冰厚度观测数据折算到标准状态下覆冰厚度进行高度和线径修正,利用克里格插值技术计算得到覆盖全省地理范围的覆冰厚度数据,对全省不同地区的覆冰数据利用极值模型进行重现期覆冰厚度计算,首次利用覆冰数据法得到不同重现期覆冰厚度分布图,并对基于不同气象参数的回归法覆冰分级进行了探讨。30-year data from all the icing observation stations in Liaoning are collected,which is reduced to the standard state of ice thickness,and the height and line diameter correction is made. Kriging interpolation method is used to get the ice thickness data covering the whole province. For the ice data of different areas,extreme value model is used to calculate ice thickness of different return period. Based on ice thickness data,icing-region ranking map for Liaoning electric power system is obtained for the first time. And also based on regression of different meteorological parameters,icing region ranking is discussed in this paper.
