To improve the tennis skills of China’s women single, find the changes tactics and winning factors and give some references for the targeted training of the athletes and the cultivation of back-up talents. This thesis, using the methods of literature review, video observation, comparative analysis, and mathematical statistics, analyzes the techniques from the aspects of serve,reserve,net front technology, and forehand and backhand, by using Li’s statistics in Australian Open Tennis Championship during the year of 2010 to 2014.

Serve the increase of speed increase and placement of threatening, this change has helped to serve tactics cohesion and scoring more favorable, so serve change is the key factor for li na won the Australian open final.Reserve:Receiving forehand straight back to increase, the road there are fluctuations, backhand road back to the ball. Outside, serve the first rise, return route straight lines and large slash use rises, placement is a deep ball increases; Pick up after serve the first stable, back to the ball straight line to reduce road increase, the placement of the ball is given priority to, deep ball up; Inside serve the first stable, route is given priority to with middle road, in the placement of the ball.
