摘要：

The dynamics of population reproduction and spatial distribution is studied in terms of a two-dimensional continuous flow model. A second order non-linear partial differential equation is formulated, but no analytical solution has been found for the history of flows over time. Equilibrium solution with spatially uniform population density exists. Stability, and for the case of pure diffusion, uniqueness are examined. (C) 2003 Elsevier Science Ltd. All rights reserved.
