利用贵州省铜仁地区10个站点1980～2009年和30个乡镇自动站2001～2009年各年的年平均气温、≥10℃的活动积温、多年极端最低气温、年降水量、生长期月降水、相对湿度、日照百分率、干燥度等8个气候变量,进行经验正交函数分解,确定优质绿茶气候区划指标.应用聚类分析,将贵州省铜仁地区划分为4种不同类型的优质绿茶气候区,为铜仁地区,乃至贵州茶叶产业基地建设提供了科学依据.%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.
