Liuzhou is one of the serious acid rain area in China.The paper adopted contrast research method.The content of several chemical element of Pinus massoniana's tree ring in Changtang and Sanmenjiang in Liuzhou were analyzed and find out the regulation of acid rain and the growth of Pinus massonian's tree ring.The result indicates that acid rain may cause the content of N,P,K ascend and the content of Ca,Mg,Zn,Mn,Al descend in 30 years.Due to the different polluted degree of acid rain in Changtang and Sanmenjiang,,the increased content of N、P、K and the decreased content of Ca、Mg、Zn、Mn were different.
