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.
