Real-time irrigation forecasting system and method based on regional soil moisture status monitoring and remote sensing data

The invention relates to a real-time irrigation forecasting system and method based on regional soil moisture status monitoring and remote sensing data. The irrigation forecasting system comprises a remote sensing information soil moisture status inversion module, a regional soil moisture status real-time monitoring module and a regional real-time irrigation forecasting module. The remote sensing information soil moisture status inversion module transmits a determined regional soil moisture status spatial distribution coefficient to the regional real-time irrigation forecasting module; the regional soil moisture status real-time monitoring module transmits a regional real-time soil moisture status monitoring result to the regional real-time irrigation forecasting module; the regional real-time irrigation forecasting module selects a pixel corresponding to the soil moisture content or a soil moisture status monitoring point, fitting is carried out on the pixel and an actually measured value, a coefficient of distribution from a point scale to a regional scale is obtained, the coefficient and the soil water content or soil moisture status data monitored in real time are combined to simulate a regional scale soil water content or soil moisture status real-time spatial distribution map, and real-time forecasting of a regional irrigation situation is finished. The real-time irrigation forecasting system and method can be widely applied to the fields of irrigated area irrigation decision making and managing, regional drought monitoring and the like.
