For the ecosystem of the northwest shelf of the Black Sea studied as an example, we construct a dynamic model of the integrated processes of development of phyto-and zooplankton, larvae, and fish and the variations of the concentrations of biogenic elements and detritus. The data of many-year observations over these processes are generalized and the scheme of genetic relations between these processes is proposed. By the method of adaptive balance of causes, we establish the dynamic model equations of the ecosystem. It is proposed to use the method of analytic hierarchy process for the estimation of the coefficients of the model with regard for the degree of influence of external and internal factors on the dynamics of the ecosystem. Some examples of analysis of various scenarios of the development of integrated processes running in the ecosystem are presented and their comparison with the data of many-year observations in this region is performed.
