以茶树栽培北界变化为研究对象，根据对中国未来温度变化的模拟结果，研究了未来中国茶树栽培北界的变化。目前中国茶树栽培北界大致位于秦岭-淮河，又可分为东西两段：西段为秦岭山地，由于地形作用栽培界线稳定；东段为平原丘陵，随气候冷暖变化栽培界线变化较大。根据温度变化预测，未来西段茶树适宜栽培界线仍然较稳定，而东段的北移明显，2050年将可能从目前界线向北推移153~251km，2090年可能向北推移290~477km。
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.
