Zvonareva, who entered as the top seed, was unstoppable early in the match and then held on for 6-1, 6-4 victory over Pervak for her second title of 2011 and the 12th of her career.
The world No. 3 was already ahead 4-0 in the first set before Pervak finally got on the board. After that, Zvonareva, quickly broke serve again and went on to claim the first set.
The seventh-seeded Pervak played better in the second set, but the 20-year-old had dug too deep a hole and she fell in her first WTA Tour final.
Zvonareva, who won the Doha event in February, improved to 12-16 all-time in title matches.
