摘　　要：海冰是低温条件下的海水冻结物,在我国渤海,每年冬季有4个月左右的结冰期,形成大范围的海冰。海冰具有灾害性,常对冬季海上运输及海洋生产构成危害,但因其含盐量较低,海冰还具有资源性,有可能以较低成本转化为淡水。自1995年以来,我国学者开展了渤海海冰淡化利用研究,在国家有关项目的大力支持下,已在海冰资源特性、资源量估算、海冰淡化技术和海冰水农业利用等方面均取得了一系列重要的研究进展。本文是对这些研究进展及尚需解决问题的综述。Sea ice is the frozen product of sea water under low temperature. Frozen period of Bohai Sea prolongs for about 4 months in every winter. Therefore, a wide range of sea ice is formed. Sea ice is dangerous. It often endangers marine transportation and marine industry. While sea ice has resource attribute because of its low salinity, it can be converted to freshwater with low cost. Chinese scholars have carried out the research on Bohai sea ice desalination and utilization since 1995, and have made much progress in resource characteristics, resource extent estimation, desalination technology and melt water agricultural utilization of sea ice with vigorous support from related nation projects. The paper is the review of those research progress and the problems that still need to be solved.
