| 摘 要： | 该文提出了一种简单易行的海冰资源量遥感估算方法,包括提取海冰的结冰范围和反演冰厚分布。根据这种方法,利用2000年1月30日辽东湾NOAA/AVHRR资料,进行了海冰资源量遥感估算的尝试,得到了当天的海冰厚度分布图和海冰资源总量的数据,进而讨论了估算结果的合理性。研究得出的主要结论是：（1）NOAA/AVHRR资料的第一通道数据可以用于进行海陆分离和冰水分离;（2）基于反照率与海冰厚度指数关系的冰厚反演公式,可以用于海冰厚度的遥感估算;（3）得到的海冰资源量遥感估算结果,基本上符合辽东湾海冰分布的实际情况,可以为海冰资源的开发利用提供。

| Abstract: | The paper advances a feasible estimation methodology of using remote sensing data to calculate sea ice resource which includes ice extension and inversion ice thickness distribution. Based upon which, we estimate sea ice resource using NOAA/AVHRR data on Jan.30, 2000 of Liaodong Gulf and gain the sea ice thickness distribution map and the data of the volume of sea ice resource on the day. Then rationality of the estimation result is discussed, from which some important results can be drawn as follows:1) The first band data of NOAA/AVHRR can be used to differentiate land from sea and differentiate ice from water; 2) Based on the ice thickness inversion formula which explains the relation of the albedo and sea ice thickness, sea ice thickness is estimated using the remote sensing data; 3) According to the estimation result of sea ice resource using the remote sensing, which accords with the physical circumstance of the sea ice distribution in the Liaodong Gulf, we draw the conclusion that the estimation methodology can provide the reference for the exploitation and utilize of sea ice resource. |
