Most recently, in addition to the unusual well-known 10 kpc ring seen in previous observations of M31, the presence of a second, inner dust ring was discovered in the disk of M31 (Block et al. 2006). The two off-center circular rings suggest that M31 has been distorted by very recent passage of its satellite galaxy through the disk. In this case, such a recent violent event may enhance the efficiency of star formation in the disk of M31. On the other hand, the existence of young star clusters in the outskirts of M31 disk suggests the occurrence of a significant recent star formation in the disk of M31. Most of the young star clusters in M31 have similar characteristics to the blue star clusters in LMC. Star cluster system can be a tracer of galaxy formation and assembly, in the sense that significant star cluster formation is typically produced by major star-forming episode in a galaxy. Therefore, assuming that merging/accretion event may trigger high-level star formation in the disk of M31 than in quiescent galactic disks, it is intriguing to examine the properties of star clusters related with those of M31 disk. By studying the kinematics, age, mass, and spatial distribution of young star clusters in M31, we confirm the existence of plentiful young massive clusters associated with the disk of M31, and suggest that these young clusters may be outgrowth of a suggested recent merger occurred at the center of M31 disk.
