Abstract

The invention provides a method and device for determining the drought grade of a grassland, electronic equipment and a medium. The method comprises the following steps: acquiring meteorological state data, soil state data and vegetation state data of a region corresponding to each meteorological station in a plurality of meteorological stations in a target grassland; according to various state data, determining a relative water consumption index, a standardized rainfall index, a soil relative humidity index and a temperature vegetation drought index of a corresponding area of each meteorological station; according to each index, the seasonal adjustment coefficient and the weight corresponding to each index, determining a comprehensive drought index of the region corresponding to each weather station; determining a comprehensive drought index of other areas in the target grassland by using a spatial interpolation algorithm; and determining the drought level of each region in the target grassland based on the comprehensive drought index of each region and a preset corresponding relationship. The method can comprehensively consider meteorological, soil and vegetation factors to determine the drought grade of the grassland, can more accurately and comprehensively judge the drought condition, and is more suitable for the grassland environment.

Description

technical field [0001] The present application relates to the technical field of drought monitoring, in particular to a method, device, electronic equipment and medium for determining grassland drought level. Background technique [0002] Drought is a complex natural phenomenon that occurs worldwide and is one of the most serious natural disasters in agricultural production and human life. Determining the level of drought is an important part of drought monitoring, prediction and evaluation. At present, the evaluation angles of drought levels are different, and the drought assessment indexes used are also different, but in general, the existing methods for determining drought levels are inaccurate, and the applicability to grasslands is poor, and they cannot fully reflect the grassland. arid properties. Contents of the invention [0003] In view of this, the purpose of this application is to provide a method, device, electronic equipment and medium for determining the dr...
