My simple way to solve the white-lines issue is simply to give the contourf command twice:
contourf(x,y,z)
contourf(x,y,z)
The white lines are magically disappearing, also in png files.
This works well also with alpha<1

What version of mpl are you using?
My mpl version is 0.99.1
Are you modifying the default anti-aliasing in the patch collections that
contour is creating?
Could you please tell me how to this? I am very new to matplotlib, thank you
very much if you can give me some advices.
Are you seeing the problem when using the ps and pdf backends, or only with
agg (that is, creating png files directly)?
So far I only creating png files directly. Also, how to use ps and pdf
backend?
…which has been fixed in svn.
Do you mean I should download another mpl by svn?
Thank you for your answers very much!

(that is, creating png files directly)?There are two problems that can contribute to this, one related to the
way the agg backend handles the boundaries between filled regions, and
the other a bug in path simplification, which has been fixed in svn.Eric
