In the frame of the vortex self-organization dynamics the question of the interaction of binary vortices is investigated by using a numerical model and the differences and homogeneities of binary vortices interaction under the two types of conditions of weak enviromental fields and vortices swarm ambient flow are analyzed.It is shown that under the enviromental condition of vortices group the merger process of binary vortices happened in the case of weak enviromental fields no longer occurrs;and meanwhile,the introduction of vortices swarm might lead to the intensification of vortices.
