Quantum coherence， as an important physical resource， is one of the most basic characteristics of quantum mechanics， and it is also the advantage of quantum information， which attracts the interest and attention of a large number of scientific researchers. This paper mainly discusses the coherent values of the maximally coherent mixed states in high-dimensional quantum systems under common quantum coherence measures. The analytical expressions of the coherent value of the maximally coherent mixed state in a high-dimensional quantum system are calculated under six common coherent measures.
