Abstract: Clustering analysis of short distances on tea areas of ten cities and towns and six meteorologic factors showed that tea in Shandong is distributed mainly in four ecological regions. There are Rizhao and Qingdao, Linyi, Junan and Jiaonan of Qingdao; Taian and Xintai; as well as Laoshan of Qingdao and Zhucheng of Weifang. Analysis of variation indexes on tea in each ecological areas showed that frozen injury from light to heavy on tea dispersed piebald-style. Analysis of typical relativity showed that each meteorological factor is positively correlated with the change of tissue structure in tea leaf, among these meteorological factors, the most important factors on tea variation are annual rainfall and the extreme lowest temperature, followed by average annual temperature , frost-free period and sunshine hour, January average annual temperature in January showed little influence on it. With leaf structure the thickness of palisade tissue is most sensitive to climate, then the ratio of palisade tissue to spongy tissue and the thickness of spongy tissue. The thickness of leaf and the upper epidermis showed no relationship with the meteorologic factors.
