基于树轮年代学研究方法,在鄂、豫、皖交界的西大别山北坡进行黄山松研究,建立了1915—2011年的树轮宽度标准年表(STD).结果表明:年表中较高的平均敏感度表明树轮中含有较多的气候变化的高频信息;较高的一阶自相关系数表明树轮生长存在显著的前期生长滞后效应;高信噪比和样本解释总量暗示树轮中含有较多的环境信息.标准年表序列指数与1959—2011年间气象因子的相关分析表明,黄山松树轮宽度生长受生长季末(9—10月)温度、降水量和相对湿度的影响较大;与9—10月帕尔默干旱指数呈显著正相关.9、10月的水热组合是影响小林海黄山松树轮生长的主要因子.
Based on the tree-ring chronology, Huangshan pine was made on the northern slopes of the western Dabie Mountains at the junction of Hubei, Henan and Anhui Provinces, and a tree-ring width standard chronological table (STD) was established from 1915 to 2011. The results showed that: The average first-order autocorrelation coefficient indicates that there is a significant effect of early growth retardation on tree-ring growth. The high signal-to-noise ratio and total sample interpretation suggest that the tree Which contains more environmental information.The correlation analysis between the standard chronological index and the meteorological factors from 1959 to 2011 shows that the growth of the width of the tree is affected by the temperature, precipitation and relative humidity at the end of growing season (September-October) And was significantly and positively correlated with the Palmer drought index from September to October. The hydrothermal combination of September and October was the main factor affecting the growth of the pine tree round in the Kobayashi and Huangshan Mountains.
