Aiming at the impact of multiple environmental factors on atmospheric visibility, this study proposes an entangled wave division access strategy of quantum satellite communication under the background of multiple factors in a natural environment. When each pair of ground stations distributes quantum keys, they can form entanglement pairs of different wavelengths through the quantum satellite. According to quantum entanglement of different wavelengths, many ground stations can connect to the same satellite. The simulation results show that under the same atmospheric humidity and haze particle concentration, the system’s channel capacity increases, and the bit error rate decreases from 3.3415×10-3 to 2.243×10-3. The increase in the bit error rate caused by atmospheric visibility factors will also decrease. Thus, in the environmental multifactorial context, the entangled wave-split access strategy can improve the quantum satellite communication performance.
