摘　　要：采用原子吸收光谱法研究6个不同质量水仙岩茶中的4种矿质元素(Pb、Mn、Fe、Ca),结果表明:各质量水仙岩茶中各矿质元素含量大小均为Ca>Mn>Fe,未检出Pb的存在;水仙岩茶的质量越高,Ca的含量越低,两者呈显著的相关关系(|r|≥0.8,P<0.05);而其他元素与质量好坏无显著相关关系(P>0.05),且各元素之间基本不相关(P>0.05)。The study on the mineral elements content in tea is important. In this paper, the four metal elements （Pb, Mn, Fe, Ca） in six different kinds of quality for Rock tea Shuixian have been studied, and the method of atomic absorption spectrometry was used. The results show that the quality of mineral elements in each kind of quality for Rock tea Shuixian is Ca 〉 Mn 〉 Fe, and Pb was not detected. The qual-ity of Rock tea Shuixian is better with less Ca and there is significant correlation between them （P〈0.8, P〈0.05）. While the correlation be-tween other elements and the quality is not significant（P〉0.05）,and the correlations between each element are also not significant（P〉0.05）.
