【摘要】The System of Ningxia Drought Monitoring and Early Warning considers three inflenecing fators: disaster-inducing environment, disaster-inducing factor, and hazard-bearing body. The input data of the system include GIS data, remote sensing data, and data on the characteristics of crops and the properties of soil, and early warning is performed by means of the integrated model. The system is discussed from the five aspects of system framework model, system architecture, data processing, data access, and system functionality. Based on the current advancement in this field, the system developed drought monitoring and prediction models and established the integrated operational system of data collection, processing, and output. The application proved that the system is applicable and efficient.%宁夏下旱监测预警系统考虑了孕灾环境、致灾因子、承载体特征3个方面影响因素,以地理信息、遥感资料、作物特性、土壤特征等作为输入数据,通过综合模型进行监测预警.从系统框架模型、系统体系结构、数据处理流程、数据访问、系统功能5个方面对系统进行了设计,吸收了多个项目研究成果,建立了干旱监测预警模型,实现集气象数据收集、处理、输出于一体的业务系统.通过具体实例验证了系统的可用性和运行效率.
