| 摘 要： | 海冰是影响渤海冬季海运的严重灾害,研究年度周期内海冰时空变化具有重要意义。依据研究内容选择11期具有代表性的中分辨率成像光谱仪(MODerate-resolution Imaging Spectroradiometer,MODIS)影像数据,采用ENVI(The Environment for Visualizing Images)软件进行预处理,利用目视解译方法提取海冰面积与空间位置信息,采用ArcGIS软件制作了海冰时空变化图、海冰结冻与融化过程变化图。最后,对海冰面积变化、海冰结冻与融化过程进行了详细分析。研究结果表明,利用MODIS影像进行年度周期内海冰变化分析技术方法是可行的。

Variation analysis of sea ice in the Bohai Sea in 2012 based on MODIS |
| |
| Abstract: | Sea ice is one of the severe hazards affecting sea transportation of the Bohai Sea in winter. It is extremely urgent to investigate spatio-temporal annual distributions of sea ice by satellite remote sensing and geographic information system. Eleven typical MODIS imageries were selected and preprocessed with ENVI software. Sea ice distribution area and spatial pattern were retrieved by using visual interpretation method. The sea ice spatial distribution map, spatio-temporal distribution map, and the processing map from sea ice to melt sea water were made using ArcGIS software. The changes of sea ice area and the melting process of sea ice were discussed in detail. Research results showed that it was feasible to analyze annual sea ice distribution changes by MODIS imageries. |
