中文摘要：
研究了寒区水库冰盖厚度的增长变化情况，改进了前人的寒区水库冰盖热力模型，采用与温度有关的分段函数的形式代替以往一维热传导方程中经验性常数的导温系数，采用隐式的差分格式进行离散，根据2008年冬季与2009年冬季黑龙江红旗泡水库的气象数据，对水库冰盖厚度增长情况进行了数值模拟，并将模拟结果与现场观测的冰厚数据进行了对比．
英文摘要：
The research is carried out on the growth and changes in the thickness of the ice caps in the reservoirs in the cold regions, with the findings that have improved previous thermodynamic models of the ice caps in the reservoirs in cold regions by use of the form of temperature-referenced relevant section function, rather than the ever one-dimensional thermodynamic modal of the empirical constant temperature conductivity, and the implicit difference scheme for discrete. The numerical simulation of the thickness of ice caps is run by reference to the meteorological data in Hongqipao Reservoir, Heilongjiang, in the winter of 2008 and 2009, with its results contrasted with the data of ice thickness captured from field study.
