【摘要】 为分析黄河封河期气温变化对河冰厚度的影响,基于冰与水的导电特性差异性原理,建立了冰情自动监测系统,于2014年对黄河三湖河口水文站、包头水文站、头道拐水文站和万家寨水库库尾河段4个监测点封河期气温与冰厚进行了连续自动监测。监测结果表明,三湖河口水文站与头道拐水文站监测得到的数据客观上反映了负积温同冰厚的关系,引入斯蒂夫模型,建立了黄河封河期负积温变化与冰厚变化的经验关系式。更多还原

【Abstract】 In order to analyze the influence of temperature change on the ice thickness in ice freezing period of the Yellow River, an automatic monitoring system was established based on the principle of differentiation of electrical conductivity between ice and water. The temperature and ice thickness were continuously and automatically monitored at four monitoring stations of Sanhuhekou, Baotou, Toudaoguan and Wanjiazhai Reservoir tail reach in freeze-up period of 2014. The monitored results show that the data obtained from Sanhuhekou Hydrological Station and Toudaoguai Hydrological Station objectively reflect the influence of negative accumulated temperature on ice thickness. Therefore, based on the data obtained from the two hydrological stations and Stephen Model, the relationship between negative accumulated temperature change and ice thickness change has been established during the freezing period of the Yellow River.更多还原
