【摘要】：震后地震应急灾情的准确、快速评估(盲估)是有效地震应急决策的关键之一。为提高应急灾情评估的速度与准确性,文中提出开发基于千米格网技术的地震应急灾情预评估数据。阐述了预评估数据计算模型,包括承灾体数据、灾情计算用致灾因子和计算公式。介绍了千米格网地震应急灾情预评估数据计算的算法,该算法通过对计算参数的空间化和地图代数的应用实现。最后论述了预评估数据在地震应急灾情评估与应急救援中的应用,并以近期中国大陆发生的2次实际破坏性地震为实验案例,展示和检验了其应用。实验结果表明,千米格网地震应急灾情预评估数据能较好地提升灾情评估速度和准确度,还能精细地展示灾情的空间分布,为地震应急指挥和救援提供参考。
[Abstract]:Rapid assessment (blind estimation) is one of the keys to effective earthquake emergency decision. In order to improve the speed and accuracy of emergency disaster assessment, this paper presents the development of earthquake emergency disaster pre-assessment data based on kilometer grid technology. The calculation model of pre-evaluation data, including the data of disaster bearing body, the disaster factors and the calculation formula for disaster situation calculation, are expounded. This paper introduces the calculation algorithm of earthquake disaster pre-assessment data based on kilometer grid. The algorithm is realized by the application of spatial computing parameters and map algebra. Finally, the application of pre-evaluation data in earthquake emergency situation assessment and emergency rescue is discussed, and its application is demonstrated and tested by two actual destructive earthquakes in mainland China. The experimental results show that the pre-assessment data of earthquake emergency situation based on kilometer grid can improve the speed and accuracy of disaster assessment, and can display the spatial distribution of disaster situation, and provide reference for earthquake emergency command and rescue.
