It's not moire.

I see the bands you speak of. I can think of two possible causes - first is that you enhanced the brightness of this image significantly during post processing, causing posterization. Second is that you used a very low quality JPEG setting causing visible artifacts.

Thank you very much, Mark! You comment is very helpful, I'll try to lower the brightness andcontrast and see what will happen. But I shot in DNG and exported in JPEG. Did you mean that I should set to export high quality JPEG files in LR? If so, I will try to find the place to change the setting in it.
