Dynamical models of middle-latitude forest

Abstract: Model of middle-latitude multiform forest for local ecology purposes is presented. Simulation deals with numerical solving the dynamical system of differences equations for forest biomass density based on classic Volterra model. We propose sequential construction of system of dynamical equations: basic (vary simple model with possibilities of analytical solution) — more complicated concentrated model for forest population – final spatially-distributed cellular automata model. Local ecology approach implies use of system of equations with boundary conditions suitable for concrete locality. We perform ecological forecasting on the simulating with different external parameters (humidity, amount of residues, thermal condition, antropogeneous action etc.).
