自2002～2003年度首次启用遥感技术监测黄河凌情以来,到目前已连续进行了10个年度。10个年度的生产实践表明:国产高分辨率卫星遥感数据能够有效跟踪黄河凌情的发展过程,实现黄河凌情的日动态监测、重点时段的精细监测和突发凌汛灾害时的实时监测。黄河凌情尤其在封开河阶段,日变化非常显著,中巴资源卫星作为国产高分辨率可见光民用遥感卫星的代表,以其大视场、高空间、高时间分辨率的特点,动态监测凌情,基本做到每天实现一次全覆盖监测的能力,配合其他如中国遥感卫星等高分辨率可见光、雷达数据,初步实现了凌情发展预估、开河前的河道槽蓄水量计算、封开河期间冰凌险情监测以及发生凌汛灾害时灾情信息采集与评估,为黄河防凌调度、决策会商提供了有力的技术支持。
Since the first remote sensing technology was launched in 2002-2003 to monitor the situation of the Yellow River, up to now, 10 consecutive years have passed. The 10 annual production practices show that the domestically produced high-resolution satellite remote sensing data can effectively track the progress of the development of the Yellow River, and realize the daily dynamic monitoring of the Yellow River, the fine monitoring of key periods and the real-time monitoring of sudden flood disaster. In particular, during the closure of the Yellow River, the Qinghai-Tibet River has a very significant change in its daily variations. As the representative of China-made civilian high-resolution visible remote sensing satellites, China Resources Satellite (CMB) satellites are dynamically monitoring their feelings on the basis of their large field of view, high space and high temporal resolution , The basic ability to achieve a full coverage of monitoring every day, with other high-resolution such as China’s remote sensing satellites, visible light, radar data, the initial realization of the development of the estimated conditions of love, pre-open river channel trough water storage, Ice danger monitoring and flood disaster information collection and assessment of the disaster, the Yellow River anti-Ling scheduling, decision consultation to provide a strong technical support.
