Abstract

The invention relates to a real-time irrigation forecast system and method based on regional moisture monitoring and remote sensing data. The irrigation forecast system includes a remote sensing information moisture retrieval module, a regional moisture real-time monitoring module and a regional real-time irrigation forecast module; the remote sensing information moisture retrieval module will The determined regional moisture spatial distribution coefficient is transmitted to the regional real-time irrigation forecast module; the regional real-time moisture monitoring module transmits the regional real-time moisture monitoring results to the regional real-time irrigation forecast module; For the corresponding pixel, fit the pixel with the measured value to obtain the coefficient distributed from the point scale to the regional scale, and use the coefficient combined with the real-time monitoring of soil moisture or moisture data to simulate the regional scale soil moisture or moisture Real-time spatial distribution map to complete the real-time forecast of regional irrigation. The invention can be widely used in the fields of irrigation decision-making and management in irrigation areas, regional drought monitoring and the like.

Description

technical field [0001] The invention relates to a real-time irrigation forecast system and method, in particular to a real-time irrigation forecast system and method based on regional moisture monitoring and remote sensing data. Background technique [0002] Due to the influence of global warming and the uneven distribution of rainfall in time and space, droughts have occurred frequently and intensified in northern my country, and even extreme droughts have appeared in some parts of the south. The risk of drought in agricultural irrigation areas will increase in the future. Therefore, rapid and accurate monitoring and evaluation of drought conditions can not only provide a scientific basis for water allocation in irrigation areas, but also facilitate the development of drought relief work, and play an important role in improving the management level of irrigation areas and ensuring national food security. [0003] As early as 1973, Brown and Rosenberg retrieved the thermal i...
