Abstract：

Protoplanetary disks form as a result of angular momentum conservation during the protostellar core collapse  and play an important role in planet formation. A study of  protoplanetary disks evolution is important for us to understand the formation of our solar system. In this talk, I will talk about internal and environmental effects on the protoplanetary disks evolution. For internal effects, I will talk about the accretion and disk wind. For the environmental effect, I will show the  photoevaporation  driven by the UV photons from massive stars dominates the protoplanetary disk evolution in massive clusters.
