Abstract: Soil samples from tea gardens located in Laoshan green tea planting area were tested, and the distribution and the seasonal dynamic changes of the soil organic matter, available nitrogen, phosphorus and potassium of those samples were analyzed with variance analysis and cluster analysis by SPSS. The results showed that the tea garden soil nutrients of different seasons and different locations had significant difference. The soil nutrient level in chosen tea gardens could be clustered into three types by cluster analysis. Also soil nutrient in different tea garden was found to have a distinct annual variation trend.
