Why I can't mount usb stick with my uid or gid?

Why I can't mount usb stick with my uid or gid?

[乃宏周]

I use ubuntu 12.04, and my usb stick had been found at /dev/sdb and has 2
partitions.
If I `mount /dev/sdb1 ~/work`, My usb stick can be mounted sucessfully, but
ownership of ~/work is root, so I can't write anything to it.
But if I `mount -o uid=1000,gid=1000 /dev/sdb1 ~/work`, system replies
following error message:

mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

Why this situation occurred? I'm sure that my pid and gid is 1000.
Any ideas?

What does `dmesg` say?

Because uid,gid and other parameters are given nfs, vfat file systems. 
ext3 and ext4 file systems doesn't
support this mount.
This is my test log:
$ sudo mount -o uid=500,gid=500 /dev/sdb1 /media/
$ mount
/dev/sdb1 on /media type vfat (rw,uid=500,gid=500)

If this situation is true, how should I do to change ownership after mount?
Use `chown -R 1000:1000 ~/work` ? That sounds doesn't like a good idea.

Not found a better way at present.  :(

Others have good ideas?
