The invention discloses a tunnel fire-fighting system using slope surface flowing water and pavement water as water sources. The tunnel fire-fighting system is characterized by comprising a drainage ditch, a longitudinal seepage and drainage ditch, a side ditch, a transverse drainage pipe, a pavement jet stream trough, drain dykes and a filter bed, a sand sediment trap, a low-position pool, a pump room, a high-position pool and a tunnel fire hydrant which are built near a tunnel, wherein the slope surface flowing water is used as the water source, so that sufficient water retention capacity of a reservoir can be ensured and meanwhile, cost is reduced; the drain dykes are built on a plurality of contour lines of a mountain slope to collect slope surface rainwater, so that the water source is more convenient to collect and cost is low; meanwhile, pavement water is used as the water source and supplements the slope surface flowing water, so that the water sources are more sufficient; a water quality is matched with a switching mechanism and when the water quality is unqualified, sewage is drained into a sewage pool and qualified water is drained into the high-position pool so as to avoid corrosion of acidic materials in the sewage to the fire hydrant and a pipeline.
