摘要： A method for mapping temporal and spatial stability of a cropping system comprises:
(a) providing a plurality of images in a time series, the images (i) spanning a large-scale cropping system land unit having at least one of soybean and corn crop plants planted thereon, and (ii) comprising a plurality of small-scale image subunits encompassing the large-scale cropping system land unit;
wherein images at a given element in the time series correspond to a canopy saturation time point in a growth season for the cropping system;
(b) determining at each time series element an average optical vegetative index for the large-scale cropping system land unit based on the small-scale image subunits therein at the time series element and having the crop plants thereon;
(c) determining for each small-scale image subunit having the crop plants at each time series element the optical vegetative index for the small-scale image subunit, and classifying the optical vegetative index for the small-scale image subunit relative to the average optical vegetative index for the large-scale cropping system land unit at the same time series element;
(d) determining for the time series a variability parameter of the optical vegetative index for the large-scale cropping system land unit over time;
(e) determining for each small-scale image subunit having the crop plants for the time series the variability parameter of the optical vegetative index for the small-scale image subunit over time, and classifying the optical vegetative index variability parameter for the small-scale image subunit relative to the optical vegetative index variability parameter for the large-scale cropping system land unit.
