There are many black dotted line in my hair material

They can be seen somtimes,when I render a video.

How can I remove them?

I think this problem is related to BaseHairMaterial file,but I can not fix it. Thanks!

Do you see those on the character?  Those pop up because I set the material to use dithered alpha.  Try adjusting the transparency until it looks correct on the character.
