本文基于2010年采自大别山地区黄山松、油松树轮资料分别建立了树轮宽度标准年表,利用相关函数检验了年表与附近的麻城气象站1959-2009年月平均最高气温、月平均气温、月平均最低气温和月降水量之间关系,旨在探讨黄山松、油松树轮宽度的气候意义。研究结果显示,平均敏感度、标准差、信噪比等统计量黄山松年表均高于油松年表,表明黄山松年表较油松年表包含更多的气候信息,具有更高的树轮气候学研究价值。黄山松径向生长主要受当年2-7月平均气温限制,任何月份及月份组合降水量对黄山松径向生长的限制作用均不显著;油松径向生长主要受当年5-6月降水总量限制,任何月份及月份组合气温对油松径向生长的限制作用均不显著。研究表明,在中国亚热带暖湿地区,气候要素的年际变化亦可对部分树种径向生长具有较强的限制作用,树木年轮宽度的变化对气候具有指示意义。研究结果将进一步弥补中国亚热带暖湿地区树轮宽度年表的不足,为树轮气候重建研究提供参考和依据。
Based on the data of Huangshan pine and Pinus tabulaeformis trees collected from 2010 in Dabieshan Mountains, the tree ring width standard chronology was established. The correlation function was used to test the annual mean maximum air temperature of the chronology and the nearby Macheng meteorological station from 1959 to 2009, , The monthly average minimum temperature and the monthly precipitation, the purpose is to discuss the climatic significance of the width of Pinus tabulaeformis and Pinus tabulaeformis trees. The results show that the statistics of average sensitivity, standard deviation, signal-to-noise ratio, etc. are higher than Pinus tabulaeformis chronological table, indicating that Pinus taiwanensis chronological table contains more climate information than the Pinus tabulaeformis, with higher Tree wheel climatology research value. The radial growth of Pinus taiwanensis was mainly limited by the average temperature in February and July of the same year. The limiting effect of the combined precipitation in any month and month on the radial growth of Pinus taiwanensis was not significant. The radial growth of Pinus tabulaeformis was mainly affected by the total precipitation However, the limiting effect of combined temperature on the radial growth of Pinus tabulaeformis was not significant at any month and month. The results show that in the warm and humid subtropical regions of China, the interannual variation of climatic elements may also have a strong limiting effect on the radial growth of some tree species. The change of the tree ring width indicates the climate. The results of the study will further make up for the lack of tree-ring chronology in the warm and wet areas of China, and provide reference and basis for the research on tree-ring climate reconstruction.
