Abstract

The invention is suitable for the technical field of agricultural early warning, and provides an agricultural drought risk prediction method and device, and the method comprises the steps: obtaining the original data of an agricultural drought index; performing stationary processing on the original data one by one to generate original stationary data in one-to-one correspondence; performing secondary processing on the original stationary data in one-to-one correspondence by applying primary accumulation operation to generate accumulated data in one-to-one correspondence; calculating predicted accumulated data of the original accumulated data; obtaining prediction data of the original data according to the prediction accumulation data; calculating effective prediction data of the original data according to the prediction data; and finally, establishing an agricultural drought early warning model according to the effective prediction data. The method can solve the problem that the existing agricultural drought risk prediction method cannot prevent drought disasters in time and is easily influenced by external interference factors to cause inaccurate prediction results.

Description

technical field [0001] The application belongs to the technical field of agricultural early warning, and in particular relates to an agricultural drought risk prediction method and prediction device. Background technique [0002] Agricultural drought refers to the phenomenon that the soil moisture cannot support the normal growth process of crops when the meteorological drought develops to a certain extent. Agricultural drought risk management is an important content and key link in strengthening my country's comprehensive disaster risk management system. Carrying out agricultural drought risk management is of great significance to improving regional comprehensive drought resistance and disaster reduction capabilities, effectively reducing drought losses, fully ensuring social stability, and stabilizing the achievements of poverty alleviation. Agriculture is the type of disaster-bearing body that is most directly affected by drought and has the most obvious damage. [0003] ...
