摘要：

“雪龙”号破冰船是我国目前唯一的极地考察船, 破冰航行是极地船舶的重要特征之一。以“雪龙”
号破冰船的GPS 数据为基础, 通过建立模型算法识别冲击式破冰这一特殊的航行状态, 在整个中国第28 次
南极考察航次的数据分析中, 整体识别率超过86.1%, 识别正确率达到98%以上。利用此算法, 在中国第27
次南极考察航次的破冰识别率也超过85%, 识别正确率达到93.5%。雪龙船两个航次实测GPS 数据验证了
本文算法的可用性, 而破冰识别统计结果表明, 不同航次的破冰模式具有较大的差异。

Abstract:

The XUE LONG is the only icebreaker currently deployed in Chinese polar research. The icebreaking
status is an important feature of vessels sailing in polar regions. Based on GPS data of the XUE LONG, we
designed an algorithm to recognize its crash icebreaking status. In the analysis of data obtained during the
entirety of the Chinese 28th Antarctic Expedition, the recognition rate was >86.1% and the accuracy of recognition
was >98.0%. Using the developed algorithm to analyze the data obtained during the Chinese 27th
Antarctic Expedition produced a recognition rate of 85.0%, and accuracy of recognition up to 93.5%. The
GPS data of these two voyages verified the applicability of the algorithm, and the differences between the
statistical results showed the different icebreaking states.
