| Abstract: | Supposing the geographical diffusion of population is Brown movement, the mechanics spacial interaction is explained to be a macro image of diffusion of population, the population is idenitcal particle which life is limited with.Where N. Number of particle, t. life time, A and B are parameters. The population-particles of two region alternate each other, it will produce a image showing potential characteristics under stable condition, a alternative force will produce because of the potential, it is spacial interaction. With this theory,we result in the spacial interaction will posses a nucleus.Where r is distance, b is a paramenter depend on the geographical process. We suggested the interactianal force followsWhere Fij. force which j point was acted by i point, Oj: Number of population-particles of j, Q1: the resoarce of i point, and a, K are parameters. |
