Monitoring the status of natural and technogenic complexes from space images

摘要

This paper discusses the possibilities of evaluating the status of the plant cover from multizonal space images in the zone of influence of a large natural-technogenic complex, using as an example the Monchegorsk copper-nickel plant. Indices are proposed that adequately describe the status of the vegetation, operating in three spectral channels corresponding to the red and IR regions of the spectrum. A method is developed for estimating the threshold values of toxic loadings on the vegetation in units of normalized vegetation indices by constructing and analyzing the response functions.
