The article presents a certain delay logistic equation with diffusion and spatially-heterogeneous coefficients that describe external environment resistance of population. It is expected that the near-extreme situation is realized when external environment resistance coefficient increases without limit when approaching to one of the sides of distribution area. The matter of population change dynamics is investigated by computer analysis. Based on the obtained results the conclusion of delay logistic equation with diffusion use efficiency for qualitative description of heterogeneous environment population change dynamics is confirmed.
