By using ARSTAN software to wipe off the growth trend of tree-ring width and transform the series into index form, the tree chronology of Cinnamomum camphora in Dagangshan forest area of Jiangxi Province was built, and the responses of the tree-ring width of C. camphora to climate change in study area were studied. The results showed that the built tree chronology included abundant environmental climatic information, which could be used in dendrochronological research. In study area, the tree-ring width of C. camphora was positively correlated to the mean monthly temperature in growth season, especially to that of April and May (P < 0.05). The correlation of the tree-ring width with monthly precipitation was more complicated, being significant negative with the precipitation in current May (P < 0.01) and last December (P < 0.05), while significant positive with that in current June and August (P < 0.05). The tree-ring width had a good correlation with the humidity index of current May, June, August, and September. Temperature and precipitation had obvious integrative effects on the tree-ring width of C. camphora in Dagangshan forest area of Jiangxi Province.
利用ARSTAN软件去除樟树年轮宽度的生长趋势并将该序列转换为指数形式，构建了江西省大岗山森林地区樟树的树轮年表，并研究了该地区樟树年轮宽度对气候变化的响应。结果表明，构建的树轮年表包含丰富的环境气候信息，可用于树轮年代学研究。在研究区域，樟树的年轮宽度与生长季月平均温度呈正相关，尤其与4月和5月的月平均温度显著相关（P<0.05）。年轮宽度与月降水量的相关性更为复杂，与当年5月（P<0.01）和上一年12月（P<0.05）的降水量呈显著负相关，而与当年6月和8月的降水量呈显著正相关（P<0.05）。年轮宽度与当年5月、6月、8月和9月的湿度指数具有良好的相关性。温度和降水对江西省大岗山森林地区樟树的年轮宽度具有明显的综合影响。
