The invention discloses a ballastless track space-time non-uniform temperature field monitoring system and an analysis method, and belongs to the technical field of ballastless track temperature field monitoring. The ballastless track structure temperature is monitored through the space-time non-uniform temperature field monitoring system, meteorological environment factors influencing ballastless track structure temperature field distribution are synchronously monitored, and the ballastless track structure temperature field distribution is monitored. Complete data support is provided for a ballastless track structure temperature field time-varying feature and space non-uniform distribution feature forming mechanism, and meanwhile a ballastless track temperature field simulation calculation model is constructed by combining material heat conduction parameters and a material heat conduction basic equation. And analyzing a ballastless track structure temperature field time-varying characteristic and a strong spatial non-uniform distribution characteristic formation mechanism. According to the invention, the problems that the relationship between the ballastless track structure temperature field and the external meteorological environment is difficult to explain and the time-space non-uniform distribution of the ballastless track structure cannot be accurately represented in the existing monitoring system are solved.
