Abstract: The decision of joining forces of the Second Red Army Group and the Sixth Red Army Group was made under the conditions of extraordinarily challenging circumstances and execrable living environment. It was an inevitable and tacit choice. The joining forces of the two army groups were the reuniting process of the revolutionary forces and also a great victory of the strategic shift of the Red Army. However, so far, the places of joining forces remain controversial because of the difference of identification standards of the concept of joining forces, the uncertainty of the information transferred before the joining forces, the fluidity during the process of joining forces, the dispersion of the rendezvous and the complex battlefield environment, etc.

Key words: the Second and the Sixth Red Army groups, the places of joining forces, controversy

摘要： 红二、六军团在长征中的会师是两军在极其恶劣的生存环境下所作出的一次必然而默契的决择。两军的胜利会师是红军革命力量的一次重新凝聚，也是红军战略转移中的一次伟大胜利。对会师概念标准认定的差异，加之受接应信息的不确定性、会师过程中的流动性、两军接应点的分散性以及复杂的战场环境等诸多因素的影响，使得两军会师的具体地点至今仍存有争议。
