摘　　要：海冰已经成为一种新的自然灾害,利用遥感技术实现海冰的监测技术已经十分成熟,根据海冰的光谱特征曲线,利用HJ星数据,采用4种不同方法提取海冰信息,并对不同海冰提取方法结果进行对比分析,探讨适合HJ星数据的海冰提取方法,同时分析不同提取方法的优缺点,为HJ星在海冰信息提取应用提供有益的参考.Sea ice has become a new kind of natural disasters.The technology of using remote sensing to monitor sea ice is already very mature.In this paper,the authors appliy four different methods of extraction of sea ice information based on the spectral characteristic curve of sea-ice and HJ satellite remote sensing data,then analyze the result of different sea ice extraction methods.Finally the author explored the good methods for extracting sea ice information based on HJ satellite remote sensing data.Meanwhile,they analyze the merit and demerit of different sea ice extraction methods in order to give relevant references to the extraction and application of sea ice.
