Dendroclimatology method was used to study the relationship between ring index of Pinus massoniana and three climate factors in Dinghushan, South China. The ring indices were negatively correlated with the average temperature in June, August and September, and positively correlated with the average temperature of March, whereas no statistically significant correlation was found with monthly precipitation, showing that high summer temperature could limit the radial growth of the species. Meanwhile, tree ring indices showed a strong positive correlation with the relative humidity of April, June, August, September, October and November, and also with the average humidity of the whole year, indicating that atmospheric moisture could not fully satisfy the growth of Pinus massoniana despite of abundant rainfall. The possible impact of climate change on the growth of Pinus massoniana was discussed accordingly.
运用树木年轮气候学方法，研究了中国南方鼎湖山马尾松年轮指数与3个气候因子之间的关系。年轮指数与6月、8月和9月的平均气温呈负相关，与3月的平均气温呈正相关，与月降水量无显著相关性，表明夏季高温会限制该树种的径向生长。同时，树木年轮指数与4月、6月、8月、9月、10月和11月的相对湿度以及全年平均湿度呈显著正相关，表明尽管降雨量充沛，但大气湿度仍不能完全满足马尾松的生长需求。据此讨论了气候变化对马尾松生长可能产生的影响。
