遥感卫星灾害应急监测效能评估指标体系构建

Efficiency Evaluation Index System Establishment for Disaster Emergency Monitoring Based on Remote Sensing satellites

遥感卫星广泛应用于包括防灾减灾在内的多个领域,发挥了巨大的社会效益;自然灾害应急对卫星监测的需求具有针对多时空要素的动态高效多源多维的特点,而卫星的全球化可重访、无国界观测能力与灾害的监测需求高度契合;在研究分析遥感卫星在灾害应急任务中的能力需求和应用模式的基础上,从单项性能、能力指标和应用效能三个层次展开分析,构建遥感卫星灾害应急监测效能评估指标体系,给出主要指标的评估方法,为我国卫星有效用于国内外重大灾害应急监测服务提供有效的评估手段和技术支撑。

Remote sensing satellites are widely used in many fields,including disaster prevention and mitigation,and bring great social benefits.The demand of natural disaster emergency for satellite monitoring has the characteristics,which is dynamic,efficient,multi-dimensional and multi-source,for multi-temporal and spatial elements;while the globalized revisit and the observation across borders for satellites is highly consistent with the demand of disaster monitoring.Based on the research and analysis of capability demand and application mode for remote sensing satellite in disaster emergency tasks,this paper gives analysis from three levels,which are single performance,capability index and application efficiency.This paper also establishes the emergency evaluation index system for disaster emergency monitoring based on remote sensing satellites,and gives the evaluation methods for primary indexes,which provide effective evaluation means and technical support for satellite applications in domestic and foreign major disaster emergency monitoring services.
