众多国家和地区对非常规水源利用一直给予研究和重视。冬季海冰覆盖条件下，融水质量变化特征不同于常规灌溉，研究和掌握其规律对咸水冰资源综合利用十分重要。利用冬季室外冰柱、土柱实验，以实时监测海冰消融全过程为手段，深入分析冬季覆冰条件下海冰融水水量及总盐动态变化。实验结果表明：融水量最大值出现在下午15时左右；覆盖海冰条件下，海冰消融入渗过程分为集中排盐、深度脱盐、淡水入渗三个阶段。实验结果可为冬季覆冰或咸水结冰灌溉提供技术参考。

Many countries have been taking research on and paying attention to the use of unconventional water resources.In win-ter,sea ice covers on soil,and thus the variation of quality of melted water differs from conventional irrigation water.A thorough understanding of this is of great importance to comprehensively utilize salty ice resources.In this paper,winter outdoor ice col-umn and soil column experiments were carried out by real-time monitoring of sea ice melting in the whole process,and amount and Ec dynamics of melted water were analyzed under sea ice covering conditions.The experimental results showed that,the maximum amount of melted water occurred at about 15:00 pm;under ice covering conditions,ice melting process can be divided into three stages,i.e.,concentrated salt drainage,purity desalination,and fresh water infiltration.Our results could provide technical reference to the winter sea ice or salty water irrigation.
