This paper deals with the tree-ring growth characteristics of Cunninghamia lanceolata in the edge of its central distribution area. According to the analysis of the relationship between the first and second primary components of southern oscillation index (SOI) and the D.B.H. growth of C. lanceolata in the past 20 years, the possible effects of SOI on the growth of C. lanceolata was discussed. The results showed that the D.B.H. growth model of C. lanceolata was established while the first and second primary components of SOI were regarded as variables. The simulating precision of the model reached 91.05%,which means the SOI possibly affected the D.B.H. growth of C. lanceolata significantly ( α =0.05). Tab 3, Ref 19
