An emergency descent system for an aerial work platform includes a telescopic hydraulic cylinder provided a piston rod inside, a counterbalance valve, an oil return pipe and a proportional valve. An interior of the telescopic hydraulic cylinder is divided into a cavity with rod and a cavity with non-rod. An inlet of the counterbalance valve is connected to the cavity with non-rod, and an outlet of the counterbalance valve is connected to an oil supply pipe. The oil return pipe is connected to the cavity with rod and a control port of the counterbalance valve, the oil return pipe is connected to an emergency oil source which is used for providing hydraulic oil to the oil return pipe. An inlet of the proportional valve is connected to the cavity with non-rod, and an outlet of the proportional valve is connected to the oil return pipe.
