Combined using the imitating and analytical approaches at modeling ecological-biological systems

The integrated approach for modeling the ecological-biological objects is offered. It allows to combine strong aspects of imitating and analytical approaches, includes the full set of operations from justification the choice of object before creation of set of interconnected models and formulation of hypotheses of leading mechanisms in the studied phenomenon. Application of this approach is shown on the example of modeling the dynamics of lemmings number that allowed to prove models of different classes and to formulate hypotheses of the leading mechanisms defining fluctuations of number of this type.
