Abstract: Based on daily meteorological data and tea growth data of 22 observation stations in Anhui Province from 2010 to 2015 as well as physiological threshold value of tea, we proposed an integrated climate index consisting of temperature index, relative humidity index and sunshine index that affect tea quality. The grade criteria of climate quality of tea were established by Kmeans clustering analysis and verified using chemical indices of Tingxi Lanxiang tea in Jingxian County in 2015. The climate quality of tea was estimated in Anhui Province in 2015 using the grade criteria. Results showed that the grade criteria of tea climate quality could be defined as level 1, level 2, level 3 and level 4 when the climate index was more than 0.90, between 0.75-0.90, between 0.50-0.75, and less than 0.50 respectively. The testing results indicated that the evaluated levels of tea climate quality were consistent with the actual tea quality. The climate quality of earlyspring tea and spring tea was at level 1, the climate quality of latespring tea was at level 2, and some individual sites were at level 3. The climate quality of summer tea was at level 3 and the climate quality of autumn tea was at level 2 or 3. Our results could provide scientific support for optimizing the layout of featured tea production in Anhui.
