中国城市轨道交通建设正大规模实施，按照轨道交通运营承载实体及轨道交通的客流特点，结合国内安全形势及维稳、反恐需要，轨道交通安全防范系统承担巨大的安防压力。。简述国内轨道交通安全防范系统的现状，如系统建设各行其是、系统繁简不一、系统目标各有不同，就轨道交通安防系统建设发展变化及发展趋势进行探讨，建议形成较为完备的轨道交通安防系统建设规范及行业标准，成立统一的行业风险评估机构，扩大安防系统信息数据采集范围，强化安防系统功能。通过对国内轨道交通安防系统的探讨分析及建议，以期达成行业共识，并推动轨道交通安全防范系统的建设。

China's rail transit construction in large scale implementation, in accordance with the rail transit passenger flow characteristics, combined with the situation of domestic security and anti-terrorism, rail transportation security system to bear the heavy security pressure.At present, all over the domestic rail transit security system act as one pleases,system character not, system target is different. This paper describes the status of the domestic rail transit safety and prevention system, construction of systemchanges and development trend of the development of rail transportation security is discussed, suggested the formation of rail transportation securitysystem construction and Industry Standard Specification complete, the establishment of a unified industry risk assessment agencies, expand security system information data acquisition range, enhance the security of system function. Through the discussion of analysis and suggestions on domestic rail transit security system, to achieve the industry consensus, and contribute to the construction of rail transportation security system.
