Phosphorus is an essential element for life, an innate constituent of soil organic matter, and a major anthropogenic input to terrestrial ecosystems. This paper employed the sequential extraction method for phosphorus fraction to study the distribution of phosphorus in different region in Wuyishan. Hierarchical cluster and correlation were used for investigating the relationship between the phosphorus form and tea quality-related constituents in Zhengyan Rock Tea (ZYRT), Banyan Rock Tea (BYRT) and Zhou Rock Tea (ZRT). The result showed that the concentration of phosphorus in different regions followed this order: ZYRT>BYRT>ZRT. The relative contribution of phosphorus fraction in different regions show the similar trend: Metal Oxide Bound Phosphorus (NaOH-P)>Calcium Bound Phosphorus (HCl-P)> Reduced Phosphorus (BD-P)>Adsorbed Phosphorus (NH4Cl-P). The maximum content of water extract (WE), caffeine (CF), tea polyphenols (TPP) and total amount of amino acids (TAA) in tea leaves is in ZYRT, followed BYRT, and least in the ZRT. The phosphorus forms seem to have no obvious effects on the tea quality in the ZYRT and BYRT area, while TPP and NaOH-P, TPP and HCl-P are significantly positively correlated (r = 0.912, r = 0.956, r = 0.938; p<0.01) in ZRT.
