摘要/Abstract

摘要： 采用ARSTAN软件对江西大岗山林区樟树年轮生长趋势进行去除和指数化后，建立了樟树年表，并研究了樟树年轮宽度对气候变化的响应.结果表明：所建樟树年表包含了丰富的环境气候信息，适于进行树木年轮生态学分析研究；研究区樟树年轮宽度与生长季的月均温度呈正相关，其中，与4、5月的平均温度呈显著相关关系（P<0.05）；樟树年轮宽度与月降水量的相关性较复杂，与当年5月（P<0.01）及上年12月（P<0.05）降水量呈显著负相关，与当年6月和8月降水量呈显著正相关（P<0.05）；樟树年轮宽度与当年5、6、8和9月湿润度指数的相关性较好.温度和降水的综合影响显著作用于大岗山樟树年轮生长.

Abstract: 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 prec ipitation was more complicated, being significant negative with the precipitatio n in current May (P<001) and last December (P<005), while significan t positive with that in current June and August (P<005). The tree-ring wi dth 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.
