The spatial & temporal variations of normalized differential vegetation index (NDVI) in the region of Sorsk mining & metallurgical complex (MMC) (Siberia, Russia) were investigated. Seasonally regular cycle changes of NDVI were discussed. The hypothesis about vegetation period shortening as the result of the technogenic loading of Sorsk MMC was expressed. It was suggested to use the Chebyshev polynomials as the formal tool for NDVI season variations analyzes. The mathematical simulations of NDVI season variations exhibited that the third coefficient of Chebyshev polynomials indicates shortening of forest ecosystem vegetation period. As the result, the big negative anomaly of the third Chebyshev polynomials surrounds the Sorsk MMC at the map compiled by using the approximation of NDVI season variations by Chebyshev polynomials. This anomaly was interpreted as the result of Sorsk MMC loading on the surrounding forest ecosystems.
