The invention belongs to the technical field of vehicle hydraulic systems and relates to a load-sensitive control hydraulic system which comprises a hydraulic oil tank, a load-sensitive pump, a shuttle valve, a flow amplifier, a steering gear, two steering oil cylinders and an electromagnetic valve. Oil enters a port S of the load-sensitive pump from the hydraulic oil tank, a port B of the load-sensitive pump is connected with an HP port of the flow amplifier, a port P, a port T, a port R, a port L and a port Ls which are correspondingly connected are formed in the flow amplifier and the steering gear respectively, a port CL and a port CR which are reversely connected with the two steering oil cylinders in parallel are further formed in the flow amplifier, a port EF of the flow amplifier is connected to a port P of the electromagnetic valve, a port HT for returning oil to the hydraulic oil tank is further formed in the flow amplifier, two oil inlets of the shuttle valve are connected to the port Ls of the flo
