Can anyone help me if i can batch change aspect ratio of mkv video ,is there a software to do it? or avisynth script? and is there any way to permanent extract something from mkv's video like the subtitles?

this will work with extracting stuff from MKV MKVExtractGUI-2

Moving you to our video conversion section.

You can use mkvmergegui to change aspect ratio. If you want to batch it you must make some script for the mkvmergegui or mkvpropedit.

Blakz: http://forum.doom9.org/showthread.php?p=1614536 . It changes the aspect ratio to 16:9

Batch code example

FOR /R %%I IN (*.mkv) DO (mkvpropedit "%%~I" --edit track:v1 --set display-width=16 --set display-height=9 --set display-unit=3)

Put the text in a file and name it like fixmkv.bat.
Move mkvpropedit.exe and fixmkv.bat to the folder with the mkvs.
Run fixmkv.bat.

Thanks it works for some of the anime , but will it loosen the quality of video when changing aspect ratio? or its diffrent from upscaling?

No. It just changes the header in the mkv file. No video reconversion.
