ISSN: 0024-1148 Russian Journal of Forest Science. 2014, No. 5, pp. 3-12 DYNAMICS OF SPECTRAL BRIGHTNESS FOR SPECIES/AGE STRUCTURE OF GROUPS OF THE FOREST TYPES ON LANDSAT SATELLITE IMAGES V. M. Zhirin, S. V. Knyazeva, S. P. Eydlina Center of Forest Ecology and Productivity, Russian Academy of Sciences Profsoyuznaya st. 84/32 bldg. 14, Moscow, 117997, Russia E-mail: vmzh@smtp.ru Received: 22 November 2013 The correlation between spectral characteristics of Landsat 5/TM multizone space image and species/age structure of forest ecosystems is studied. The parameters that control variability of the spectral brightness of forest ecosystems imagery are described for the cases of moss, mixed herbs, tall grasses, and sphagnum groups of forest types in Priangarskiy taiga region of Eastern Siberia. Based on the analysis of ecological dynamics of the stands of similar forest growth conditions the trends in spectral brightness dynamics are revealed for the groups of forest types. They depend on the age and coniferous species share in the stands. Acknowledgements: This study was supported by the Presidium of The Russian Academy of Sciences Program ''Wildlife: current state and challenges of development'', subprogramme ''Forest ecosystems dynamics'' for 2012-14. Keywords: groups of forest types, forest forming process, species/age structure, ecological dynamics series, spectral brightness, multizone space image, age dynamics, coniferous species, share in the stand.
