In this paper, with the data of annual average temperature, ≥10℃ accumulated temperature, the annual average extreme minimum temperature, annual precipitation, monthly average precipitation between April and October, annual sunshine hours, relative humidity and dryness index from ten manual stations during 1980 to 2009 and thirty township automatic stations from 2001 to 2009 in tongren district of Guizhou province, the empirical orthogonal function(EOF) method is applied to calculate the indices of climatic regionalization for green tea planting. And with clustering analysis, high-quality green tea planting areas were classified into four different types. The results would provide a scientific basis for the tea industry in tongren and Guizhou province.
