中文摘要：

根据中国第22次南极科考现场观测数据，建立了辨识海冰厚度的分布参数系统最优控制模型，对南极中山站内拉湾海冰厚度进行了优化辨识，辨识得到的海冰厚度与观测结果非常接近，同时模拟得到的冰内温度分布与实际观测温度也吻合良好，表明所建立的参数辨识模型及其求解算法是正确、有效的。

英文摘要：

Based on the observation data of the 22^nd CHINARE （2006）, an optimal control model about distributed parameter system which can identify the sea ice thickness is established. The identification and optimization for the sea ice thickness of Nella Fjord off Zhongshan Station are presented. The identification results show that firstly the sea ice thickness is corresponding with the observation data and secondly the distribution of temperature within ice is similar to the real observation data. Hence, the identification model and optimal algorithm are correct and effective.
