摘要： 极地海冰是全球气候系统的重要组成部分，具有一定的季节和年际变化，它对极地科学考察有着重要影响。本文利用MODIS L1B级数据，经监督分类提取冰雪二值图并计算海冰面积，分析2000—2014年中山站附近地区的海冰的季节性和年际变化；结合Landsat影像及雪龙船航迹数据，分析2007—2012年雪龙船到达中山站的航迹特点，为极地科学考察提供参考。研究结果表明，2000—2014年中山站附近地区海冰年际变化规律大体一致，且在每年8月至次年3月有明显的季节性变化规律——海冰面积在9月底10月初达到最大值，在2月中下旬达到最小值；雪龙船到达中山站时间为该地区海冰融化的初期，其航迹特点与海冰分布密切相关。

Abstract: Polar sea ice is an important component of the global climate system, and has a great impact on polar expeditions. Using binary images of ice and water with supervised classification by MODIS L1B data, we analyzed seasonal and interannual variations in sea ice around Zhongshan Station between 2000 and 2014, combined with Landsat images and voyage data for an icebreaker (MV Xuelong) between 2007–2012. We demonstrate that for that area surrounding Zhongshan Station between 2000 and 2014, interannual variation in sea ice was consistent, and the seasonal variation of sea ice between August and March was significant. The area of sea ice reached a maximum in late September or early October, and a minimum in mid to late February. The arrival time of Xuelong at Zhongshan Station was consistent with the initial stage of sea ice melt, and the track characteristics of Xuelong closely related to the distribution of sea ice.
