Abstract. The bloks which are a structural part of the ecological fertility model in the mountain-forest brown and mountain-forest brown soils on the south-eastern slope of the Great Caucasus besides an importance of the ecological models composition have been analyzed in the article. By the main purpose of the given investigations a creation of ecological models of fertility was mountain-forest brown soils (middle mountain broken) and mountainforest brown soils (low mountain (mean broken), interrelation and dependence of biocenosis condition on the environment factors are studied a role of the main parameters (climate, relief, soil and etc) is revealed, the real and optimal parameters of the environment are established for the ecological models blocks creation. The model consists of 7 (seven) blocks: agroecological block soil structure block, soil regimes block, soil features block. value block, agromelioration block and forests biometric block. During the model blocks compiling the main diagnostic indiced as a granulometric composition, humus quantity and supply, water suspension pH, NPK, bulky mass, porosity and water-stable aggregates (> 0,25mm and > 1,00mm) in the mountain-forest brown and mountain-forest brown soils have been taken into account. A comparative character of the ecological fertility models in two different soil types which are dominant in forest ecosystems has been given.
Key words: soil fertility model, agroecology block, soil composition block, agromelioration block, forest biometric block.
