Through positioning research methods, the representative tea garden soil pH, soil texture, soil organic matter and soil cation exchange capacity of typical tea plantation in Jiangsu province were monitored. The results showed that the 0~20 cm soil acidification rate of 67 percent tea gardens was more than 0.1 pH per year, 33 percent was more than 0.2 pH per year and 50 percent the tea gardens has a pH value much lower than 4. Soil acidification of upper layer is the most serious. The acidification rate of tea garden soil had a significant difference compared with natural soil. Tea garden soil acidification rate had a direct relationship with the basic physical and chemical properties of soil itself.
