Trends of climatic changes of wood phytocenoses of the western slopes of Subpolar Urals

In work results showing the basic directions of density crone changes in foothill and mountain forests of Subpolar Urals for 18 years time period (1988-2006гг) on materials of satellite images Landsat analysis are presented. Attraction of series of winter images from the period 1988-2006 y. and method of spectral mixtures decomposition has allowed to establish changes of crones density parameter of not disturbed phytocenoses on the average up to 1-2% a year on sites, before generated larch gorests and light forests ofecotone zones near to border of forest-tundra. The most stable characteristics are noted for class of taiga forests.
