Application spatial statistics methods and geoinformation modeling open a new opportunities for analysis of long-term changes in forest and estimation of forest ecosystems disturbance. This paper presents the results of application of spectral reflectance obtained from Landsat TM data for estimation disturbance of forest ecosystems typical for forest-steppe zone Central Russian Upland. The Possibility of using near infrared surface reflectance values, calculated in cells of regularly net, for mapping forest ecosystems disturbance was shown. By using ArcGIS geoinformation system relation between age of forest stand and surface reflectances was studied. Using Landsat multispectral data time series obtained 1986-2011 the dynamic of forest disturbance due to clear-cuttings was estimated. It has been established that percent of strongly disturbed ecosystems decreased in 2,5 times. The cartograms characterizing spatial-temporal changes in forest stand were obtained. Obtained results can be used to geoinformation mapping forest ecosystems disturbance.
