A light-emitting warning rope (100) is provided with one end integrated to a tent (200) and other end integrated to an anchoring point (300). The light-emitting warning rope (100) is disposed between the anchoring point (300) and the tent (200) to provide a tension to set the tent (200) upright. The rope comprises a light-emitting core (10) and a structural rope (20). The structural rope (20) comprises a plurality of bearing yarns (21) which is knitted into a strip body with the light-emitting core (10) as an axis, and the strip body knitted by each bearing yarn is knitted in a mesh shape on the radial side and has a plurality of gaps through which light from the light-emitting core (10) is transmitted. In any segment of the rope, the light-emitting core (10) has a stretching length less than that of each bearing yarn, so that the axial tension acts substantially on the bearing yarns (21) when the rope suffers an axial tension.
