| 摘 要： | 利用“北京一号”小卫星全色和多光谱影像对冬季渤海海冰进行了监测。根据多光谱谱段特征和现场测试的海冰光谱之间的对应关系, 建立了卫星影像冰水识别、渤海海冰外缘线的模型, 估算了海冰面积及判别海冰发展趋势;对卫星影像数据进行监督分类, 建立了相应的分类模型;根据海冰类型的不同将海冰区域进行了划分, 并作为对海冰灾害严重程度的判别依据;以2007年度冬季为例, 对渤海海冰的分布面积进行了统计, 与海冰监测业务中使用的MODIS数据反演结果进行了对比, 对比结果显示“北京一号”卫星可以为海洋监测和预报服务部门提供高分辨率海冰遥感信息, 并为我国海冰灾害的防范提供可靠有效的资料。

| Abstract: | Using “Beijing No.1” small satellite panchromatic and multispectral images the sea ice in the Bohai Sea in winter was monitored.According to the corres-pondence between spectral characteristics of multispectral and field testing of the ice spectrum, water and ice satellite image recognition model and the outer edge of sea ice recognition model are established to estimate the sea ice area and analysis sea ice trends.According to sea ice type the ice area was divided to classify the severity of the ice disaster.For example, winter of 2007, the statistical area of sea ice is close to the results of the operational inversion MODIS data.“Beijing No.1” satellite can provide high-resolution remote sensing of sea ice for the ocean monitoring and forecasting service.And it provide reliable and effective disaster information for the comprehensive survey and evaluation of offshore marine sea ice surveys. |
