Objective To solve the divergence of black hole＇s entropy. Methods Using the generalized uncertainty relation, the number of quantum states is calculated, and the entropy of G-H-S black hole is obtained. Results The divergence is removed by using this method without any cutoff, meanwhile the conclusion that the entropy of a black hole is proportional to the area of its event horizon is got. Conclusion Using the generalized uncertainty relation to calculate the entropy of a black hole, the divergence will be resolved.
