摘　　要：本文提出面向流域洪涝灾害监测的分层次卫星组网对地观测任务规划方法,以长江流域重庆段和城陵矶段为试验区,进行被动、主动规划。结果表明,该方法能够提供流域洪灾区域指定时段的多尺度卫星组网协同的有效观测信息,为及时调动卫星资源、快速响应洪灾监测需求,以及获取灾害预警、决策、评估卫星数据提供重要的技术支撑。A hierarchical satellite network task planning method for ground observation tasks aimed at monitoring flood disasters in river basins is proposed.Taking the Chongqing and Chenglingji sections of the Yangtze River basin as experimental areas,through passive and active planning.The results show that this method can provide effective multi-scale satellite collaborative observation information for designated time periods of flood disaster areas in the basin.The proposed method can provide important technical support for timely mobilization of satellite resources,rapid response to flood monitoring needs,and acquisition of satellite data for disaster warning,decision-making,and evaluation.
