| 摘要: |
| 文章根据2005—2017年滨州市海域冬季各类海冰监测数据资料，对冰日、冰期、冰型、冰厚、浮冰密集度和结冰范围等冰情要素进行分析，总结海冰的时空分布和冰级特征，为进一步开展相关海域的海冰灾害研究和防灾减灾工作提供必要的参考。研究表明，滨州市海域的总冰期一般为60～80 d，其中严重冰期约为25 d，河口和浅滩等近岸海域冰情较重；冰型、冰厚和结冰范围等在不同冰期和冰级具有不同特点，对海上设施和海上活动造成不同程度的影响。 |

| Abstract: |
| According to the sea ice monitoring data in winters from 2005 to 2017 in the sea area of Binzhou city,based on the analysis of elements including date,period,type,thickness,concentration and extent of sea ice,the characteristics of temporal and spatial distribution of sea ice were summarized to provide the necessary reference to further works for research of sea ice disaster and disaster prevention and mitigation in related sea area.The research showed that the total period of sea ice in Binzhou sea area is generally 60~80 d,of which,the severe period of sea ice is about 25 d,ice condition in coastal waters of estuaries and shallows; the type,thickness and extent of sea ice have different characteristics in different period and grade of sea ice,and have varying degrees of impact on maritime facilities and maritime activities. |
