基于遥感的海冰信息检测及其变化分析

Retrieval and Mutation Analysis of Sea ice Information Based on Remote Sensing

以中分辨率成像光谱仪(MODIS)影像为数据源,同时对可见光、近红外和热红外的多个波段进行了计算,分析了冰雪反射率的特征属性,辅以归一化雪被指数和辐射亮温相关理论,总结出了一种基于数据挖掘的海冰信息反演方法。并以辽东湾为研究对象,对辽东湾海冰信息进行了提取,根据提取数据建立预测模型,预测了未来10年的海冰变化情况。

With the MODIS image as the data source,the article calculates the multi - bands of visible light, near infrared light and thermal infrared light. Through the analysis of the characteristic properties of snow and ice reflectivity and combining with normalized snow index and related theory of radiation brightness temperature, the article su mmarizes a kind of sea ice information inversion method based on data mining. In addition, taking Liaodong Bay as the research object,the article extracts information of sea ice in Liaodong Bay. Then a prediction model is established based on the extracted data, which can forecast changing situation of sea ice for the next ten years.
