    Response of Pinus massoniana tree-ring width in the Jiangle Area of Fujian Province to climate change

    • 摘要:
      目的研究福建将乐地区马尾松年轮宽度对气候变化的响应,为本地区的树木年轮生态学研究提供参考,为当地马尾松的生产、农林业的发展提供数据支撑。
      方法以福建将乐林场采集的80根马尾松树芯为对象,运用ARSTAN程序建立差值年表和标准年表,通过相关函数、响应函数、单年分析等方法研究马尾松径向生长对气候因子变化的响应,并采用响应面函数建立树木径向生长−气候因子关系模型。
      结果马尾松年轮宽度序列对气候变化相当敏感,上一年5月到当年12月的月降水量和月平均气温的响应函数模型可解释年轮宽度变化的57.43%;温度对马尾松径向生长的影响存在一定“滞后性”,上一年6月平均气温促进马尾松径向生长;月降水量和月极端最低气温是马尾松抽梢期生长的气候限制因素,当年抽梢期的降水和极端最低气温对马尾松年轮宽度有显著的正效应,其中当年3月份的降水和极端最低气温对马尾松年轮宽度的作用尤为显著;月极端最高气温是马尾松伏旱期径向生长的气候限制因素,其中8月份的气温对马尾松年轮宽度表现出显著的负效应。
      结论该研究地区马尾松生长具有明显的季节性,马尾松年轮宽度序列对气候变化相当敏感。建立的马尾松径向生长−气候因子关系模型R2为51.2%,进一步验证了当年的逐月气候因子对马尾松径向生长的影响,该模型可较好地模拟马尾松树木径向生长对气候的响应。

       

      Abstract:
      Objective This paper aims to study the response of the annual ring width of Pinus massoniana to climate change in the Jiangle Area of Fujian, eastern China, and provide reference for the study of tree ring ecology in the region and data support for the development of local masson pine production and agroforestry.
      Method In this study, 80 Pinus massoniana cores collected by Fujian Jiangle Area were used as objects. The ARSTAN program was used to establish the residual chronology and standard chronology. The radial growth of Pinus massoniana was studied by correlation function, response function and single-year analysis, and the response surface function was used to establish a tree radial growth-climate factor relationship model.
      ResultThe results show that the annual ring width sequence of Pinus massoniana is quite sensitive to climate change. The response function model of monthly precipitation and monthly average temperature from May of the previous year to December of the same year can explain 57.43% of the variation of annual ring width. The response of radial growth to temperature has a certain “hysteresis”. The average temperature in June of the previous year promoted the radial growth of Pinus massoniana. The monthly precipitation and the minimum temperature are the climatic limiting factors for the growth of Pinus massoniana. The precipitation and low temperature have a significant positive effect on the annual ring width of Masson pine, and the precipitation and minimum temperature in March of that year were particularly significant for the annual ring width of masson pine. The highest temperature is the climatic limiting factor for the radial growth of Pinus massoniana during the drought, and the temperature in August shows a significant negative effect on the annual ring width of Masson pine.
      ConclusionThe growth of Pinus massoniana in this study area has obvious seasonality, and its ring width sequence is quite sensitive to climate change. The R2 of the radial growth-climate factor relationship model of Pinus massoniana was established, which was 51.2%, which further verified the influence of the monthly climatic factors on the radial growth of Pinus massoniana. This model can better simulate the growth trend of Pinus massoniana trees in response to climate.
