Sea ice severe degree and disaster in Bohai Sea from 1950 through 2007 promulgated by State Oceanic Administration People's Republic of China has been summarized. According to these reports and bulletins involved with sea ice severe degree and disaster, the statistical means of 5-year moving average are applied, the feedback of sea ice disaster to the societal activity in every National Five-year Plan has been exhibited, the relation between sea ice disaster and sea ice severe degree has been quantificationally analyzed. Some conclusions have been derived as follows: sea ice disaster appeared proportionably to industrial activity and sea ice severe degree, but inverse proportionnably to the understandings of cognition of defending in sea ice disasters; so that the weaken sea ice conditions could not inevitably result in the loosening of sea ice disaster.

通过归纳整理1950年以来渤海海冰冰情等级以及国家海洋局公报内的海冰灾害，并应用五年滑移平均，以反映中国"五年计划"的社会活动与海冰灾害之间的响应，定量分析海冰灾害发生率同海冰冰情等级的关系，发现工业活动的频繁程度同海冰灾害发生率成正比；人类重视程度同海冰灾害发生率成反比；海冰冰情等级与海冰灾害发生率成正比；当海冰冰情等级减轻时，海冰灾害发生率并不一定减少。

According to the energy conservation theory, BOM and CSIM4 were coupled. The BOM has no treatment on transmission solar radiation, which is of great importance when the model is adapted to Arctic Ocean. So the treatment was introduced to BOM. Through numerical test on different lead albedos, it was found that sea ice thickness is not so sensitive to lead albedo, which may be contribute to the lead occupies little ratio within multiyear sea ice pack. The reason of summer over-melt of arctic sea ice is the NCEP reanalysis downward solar radiation being larger than its reality. Then the arctic sea ice climate variability was simulated. Results showed that: simulated ice thickness change is in accord with the submarine investigated mean sea-ice draft changes. Simulated annually maximum ice thickness along the Eurasian continental oceans are closely related to the observed ones. The long-term mean simulated ice motion has the same features of the SSM/I derived ice motion. Sea ice extents in differential sub-regions have same trends comparing to the satellite passive-microwave data derived ones. Simulated ice concentration is closely related to the observed in the Arctic sub-regions. Sea ice flux through the Fram Strait involves ice concentration, motion and thickness. It is a composite criterion for sea ice model evaluation. The simulated ice area and volume export through the strait accord with the satellite derived or statistically reconstructed ones.(5) The simulated ice thickness climate variability and mean sea surface current of the coupled model were analyzed, results showed: the total ice volume in the Arctic Ocean has a significant decreasing trend. The volume variability is of a 10-year timescale oscillation, with two major periods of 12-13a and 18-20a. Mean ice thickness in the arctic sub-seas has different tendencies. It has an increasing trend in the Barents-Kara Sea and Baffin Bay-Labrador Sea, and decreasing in the others. The characteristic time scale of 7-10a wherein the river discharges leads the Fram Strait ice volume export is about the period that river water takes to be conveyed across the Arctic Ocean.(6) Using the simulated ice distribution in the Arctic Ocean and China precipitation, air temperature and SST in tropical key regions, the climate teleconnection were studied. Result showed: When the mean sea ice thickness is large in the central Arctic Ocean and Chukchi-Beaufort Sea , and small in the Barents-Kara Sea and Baffin Bay-Labrador Sea , the precipitation in South China, Tibetan Plateau, and the north part of Northeastern China are always smaller than normal, and v. v. When the mean ice thickness is small in CA, BC, East Siberian Sea and Greenland-Iceland-Norwegian Sea , and large in BL, The air temperature in north-eastern China, the southern of Tibetan Plateau, and Hainan Island, are always lower than normal, and v. v. In addition, when the sea ice is thick in BC and BL, the SST is larger in the middle and eastern Pacific Ocean, and is smaller in the tropical Southeastern Indian Ocean.

对利用沉积记录来研究海平面变化的重视程度很高，但对海平面变化对沉积盆地的影响注意甚少。建议关注海平面升降变化对盆地充填物的作用，对沉积型矿床的控制和对大陆边缘地壳变形的反弹作用过程的研究及定量模拟是一个重要方向，它可能为大陆边缘动力学研究提供一方面的思路。
