The invention discloses a multi-mode power split hybrid power transmission system, and relates to the technical field of hybrid power transmission. The power utilization degree of the motors can be improved, the power levels of the two motors are reduced, the size and the weight of the motors are reduced, and continuous rotating speeds among the three modes can be ensured. In the system, a sun gear of a first planet row, an output end of a first motor fixed transmission ratio mechanism, an input end of a first clutch fixed transmission ratio mechanism and a gear ring of a second planet row are fixedly connected; the engine is connected with a planet carrier of the first planet row through an engine fixed transmission ratio structure. The first gear ring is fixedly connected with the second planet carrier; the first motor is connected with the input end of the first motor fixed transmission ratio mechanism; the second motor is connected with the second sun gear through a second motor fixed transmission ratio structure; the two driving ends of the double-clutch mechanism are connected with the corresponding clutch fixed transmission ratio mechanisms respectively, and the driven end is connected with the drive axle.
