摘要：
In this paper, the study on the simulation of invasion species diffusion along the Qinghai-Tibet Railway is presented. On the basis of discrete diffusion model of invasion species, the diffusion model from multi-sources is studied combining with the geographical information in the studying region, and the diffusion rate from a single source is also studied. The simulation of the diffusion of invasive species along the Qinghai-Tibet Railway is discussed by using MATLAB and ArcGIS9.2 for given the diffusion coefficient, and some simulation results is obtained including from one-dimension to three-dimension. Those theoretical results can be easily used in the diffusion research on other invasion species to ensure its wide applications in the future.
