Xiaodong,

Doh!  I'm afraid I didn't read your original message carefully enough. 
I think you would have been better off with Perry's idea.   You could
still accomplish this using the csv driver and the .vrt file but you will
need to restructure your text file to use WKT format for the polygon.

eg. 

In VRT:
        <GeometryField encoding="WKT" field="wkt"/>

And your .csv file:
id, wkt
1, "POLYGON((-100 40, -90 40, -90 39, -100 39, -100 40))"

Sorry for misleading you before. 

Best regards,
