目前我国很多大中城市相继进入轨道交通时代，但科普渠道并未得到拓展，科普作品质量不高，科普工作仍远远滞后于轨道交通发展。而“微课”符合个性化学习的需求，也非常适用于移动学习时代科普知识的传播。针对当前国内轨道交通建设高速发展过程中科普工作明显滞后的现状，从匹配视角对轨道交通科普需求与“微课”关键特征进行解析，分析“科普-微课”关键特征匹配现状及存在的问题。在对“微课”部分关键特征进行改进的基础上，构建了完全匹配的轨道交通“科普-微课”体系。将微信及其公众号作为科普载体，利用“微课”在线学习资源在居民中开展轨道交通知识科普工作，可显著提高科普效果。

Many large and medium cities in China are entering the era of rail transit, yet new science popularization channels has not been developed and the quality of science popularization works has not been improved. Science popularization is lagging behind the rapid development of rail transit construction in China. However, “micro learning resources” meets the learners’ individualized needs, and is suitable for science popularization knowledge communication in the mobile learning era. In view of the current situation that popular science popularization is lagging behind in the rapid development of rail transit, popular science demand and key characteristics of “micro learning resources” are analyzed from the matching perspective to investigate the matching status and problems. On the basis of partial adjustment of the key features of the “micro learning resources”, the perfect matching “Science Popularization - Micro learning resources” system of rail transit is put forward. Taking WeChat public number as the carrier of science popularization, the teaching resources of “micro learning resources” are used to carry out knowledge popularization of rail transit among urban residents and improve the effect of science popularization.
