Abstract: The relationship between mean ring index of Pinius massoniana and mean month air temperature and precipitation in east China is analyzed by regression models. The results show that month precipitation plays an important role for the diameter growth of the pine, while mean month air temperature has a little influence on it. The diameter growth shows significantly positive response to the precipitation in April, May, June, July, September, October and November, and negative response to the precipitation in January, March and last December.
