Abstract

The invention discloses a calculation method for farmland irrigation probability index based on crop water indication lines; firstly, determining the geospatial reference and spatial-temporal resolution of regional irrigation monitoring, collecting and preprocessing multi-source remote sensing data sets, generating raster data sets with the same geospatial reference and spatial-temporal resolution, and pixel alignment; then, calculating the crop water deficit index and crop water stress index of farmland pixels, constructing a crop water scatter plot with a pixel crop water deficit index as abscissa and the crop water stress index as ordinate; then, extracting the upper boundary points and lower boundary points of the crop water scatter plot, and fitting the upper and lower indicator lines of crop water linearly; finally, establishing the probability index model of farmland irrigation according to the upper and lower indication lines, and calculating the probability distribution map of regional farmland irrigation. The invention can accurately and easily express the degree of crop water deficit and improve the physical meaning and indicative significance of the farmland irrigation probability index.
