摘　　要：基于雪/冰表面热平衡方程,得到影响雪/冰表面温度的主要因素有冰上气温、风速、净辐射、冰厚、湿度、云量及气压.考虑某一因素对雪/冰表面温度的影响,则改变这一因素,保持其它因素相对固定,从而分析该因素对雪/冰表面温度影响的敏感性.采用2009-2010年冬季黑龙江红旗泡水库现场观测所得的不同时刻冰上气温、风速、太阳辐射、冰厚等实测数据以及在中国气象网上下载得到的安达气象站的有关云量、湿度与海平面气压等数据进行统计分析,确定主要影响因素的特征.在此基础上对某一因素在实测范围内变化取值,利用雪/冰表面热平衡方程,模拟计算出对应的水库雪/冰表面温度.经敏感性分析得到了红旗泡水库上述七个影响因素与雪/冰表面温度的关系式.该结果可为气象因素对水库淡水冰的形成及数值模拟研究提供参考依据.Based on snow/ice surface thermal balance equation , the main factors influence the snow/ice sur-face temperature with ice temperature , net radiation , wind speed , ice thickness , humidity , cloudiness and air pressure .Considering certain factors on snow/ice surface temperature , changing this factor , other factors kept a relatively fixed , so as to analyze the sensitivity of the factors on the surface temperature influence .According to the statistical analysis of the in -situ observation dates in different time , which are the ice temperature , wind speed , solar radiation and ice thickness , measured in Hongqipao Reservoir Hei Longjiang Province and the data , which are cloud cover , humidity and sea level pressure in 2009 -2010 winter downloaded from Anda Weather Station in China Meteorological Data Sharing Service System , the main factors influencing the characteristic value are determined .On the basis of a range of factors in the actual value , the use of snow/ice surface heat balance equation , the corresponding reservoir simulation snow/ice surface temperature Nas Calculated was obtained through the sensitirity analysis .The formula between Hongqipao Reservoir of the above seven factors and the snow/ice surface temperature .The results can provide reference for the study of the formation and numerical sim-ulation of fresh water ice in reservoir .
