Abstract: The change of tea northern cultivation boundary in China was studied based on the temperature rise in the future. The average tea northern boundary is Qingling Mountain-Huaihe River in the history, and the border had a slight change with the fluctuation of temperature in the history. And the tea culture sector can be divided into two sections: the eastern and the western section. The western section boundary, Qinling Mountain, is stable in the history with the role of tall terrain and will be stable in the future. The eastern is plains area, and the cultivation region is changeable with the exchange of climate. As a result of temperature rising the eastern section will shift the north: the boundary would be northward over 153~251km in 2050, 290~477km in 2090.
