Abstract:

   THE analysis of the interrelations of indicators and influencing factors on the characteristics of the forest ecosystem in the suburban area of the Sochi coast is carried out. By the method of factor analysis it is determined that the state of the forest ecosystem is influenced by seven factors. At separate stages of anthropodynamic digression, taking into account from 80,3 to 93,1% of the total variability, the state of the ecosystem is estimated by the influence of three to five factors depending on the magnitude of the anthropogenic and biotic transformation of the forest environment. The status of the ecosystem and the degree of its transformation can be indicated by 12 indicators, which are the correct indicators (91,0–97,9% conjugation) of individual factors and stages of digression.

Keywords: Sochi’s coastal line, forest ecosystem, digression, indicators, factors, indicators.
