    The depolarizing channel is one of the basic quantum channels. For simplicity and generality,quantum channels with two senders and one receiver are considered to discuss the capacity of the quantum depolarizing channel. Two different capacity regions,classical-quantum region and quantum-quantum region,are deduced in theory for the quantum depolarizing channels with two senders and one receiver. The first region is comprised of the rates at which it is achievable for one sender to transmit classical information,while the other to send quantum information. The other region consists of the rates at which each sender sends quantum information. At the same time,the performance of the quantum multiple access depolarizing channel is analyzed.
