“四星三源”模式监测黄河凌汛的研究与实践

Monitoring Ice Flood of Yellow River with "Four-satellite and Three-resource" Model

在简要回顾黄河凌灾特征及所造成的历史灾害基础上,详细阐述了2002-2003、2003-2004、2004-2005三个年度利用RS、GIS等现代高新技术,采用“四星三源”模式监测黄河凌汛的内容、方法、主要技术和实施成果,得出主要结论:①“四星三源”监测黄河冰凌是现阶段在轨运行卫星中最佳的数据组合模式,对江河污染、洪涝灾害、山体滑坡等自然灾害的监测具有较好的参考和借鉴价值;②CBERS-02具有较高的分辨率,对冰凌具有良好的识别能力,其侧摆快速获取数据功能在突发灾害监测中具有广阔的应用前景。

After a brief review on the characteristics of ice flood disaster in the Yellow River and the disasters happened in the history, we illustrate the contents, the methods, the main technology and the results of using the model ＂Four-satellite and Three-resource＂ to monitor the Yellow River with RS and GIS, during three annuals from 2002 to 2005. We come to the conclusions as follow： ①The model ＂Four-satellite and Three-source＂ is the best method to monitor the ice flood disaster in the Yellow River to date. Specifically, it is to contribute to useful reference value to monitor the pollution of the river and the floodwater and the mountain landslide. ②With high resolution and the ability to identify ice and to access data through swinging rapidly, CEBERS-02 can be applied to broad application fields in monitoring the disasters.
