随着城市地铁的大规模建设，地铁车站环境和地铁火灾引起研究人员极大关注。营造良好的地铁环境目的不仅仅是提供一个安全、舒适的乘车环境，更能节省能源，降低建设费用与运行成本，由此计算流体力学软件优化地铁环控设计得到广泛的应用。通过介绍4款在地铁环控系统中应用比较广泛的计算流体力学软件以及研究现状，指出目前存在的不足，并提出了适当的建议。

Along with the development of urban Metro works, the Metro station environment and Metro fires attract great attention of the researchers. Building good Metro environment not only means to provide a safe and comfortable travel environment, but also means to reduce the energy consumption, construction cost and operation cost. CFD software is now widely used in the optimization of the environmental control design of Metro works.  4 types of CFD software that are widely used in the design of the environmental control systems of Metro works are presented, the stateoftheart of the researches on the CFD software is described, the existing problems are pointed out and proper recommendations are made.
