Based on the daily data of 3 meteorological stations of Xishuangbanna from 1961 to 2014, the temporal-spatial distributions of mean temperature, mean annual daily temperature range, ≥10.0 ℃ accumulated temperature,days of daily minimum temperature of < 0 ℃, precipitation,relative humidity and sunshine duration were analyzed in the growing season of tea plants. The results indicated that in recent 53years,not only mean temperature, but also accumulated temperature showed a clearly upward trend, relative humidity showed a clearly downward trend,the trend of precipitation was not obvious in various tea areas of Xishuangbanna. The trend of sunshine duration was not obvious in Jinghong and Menghai,it showed a clearly upward trend in Mengla. The change of agricultural climate resources would have some influences on the process of the development of the tea plant,the content of fresh leaves,the occurrence of pests and diseases,and the occurrence of agricultural meteorological disasters.
