The invention discloses an underwater acoustic sensor network routing method based on a block guide network, and relates to underwater communication. A guiding network is constructed by broadcasting a GUIDE data packet in an underwater acoustic sensor network, and transmission node paths are selected according to the hop count of a node arriving at a destination and the residual energy of the node. According to the method, a guiding network is partitioned into a plurality of guiding network units, and each guiding network unit is provided with a head node which is responsible for repairing the guiding network when the guiding network fails. And when the boot network unit fails, the head node of the network unit resends the GUIDE packet, the GUIDE packet is only transmitted in the boot network unit, and the network unit is repaired. And when more than 50% of the guide network units in the whole underwater acoustic sensor network are invalid, repairing the whole network. A network repairing mechanism is perfect
