对黄山山顶面区黄山松林分中个体年轮生长规律进行了研究,分析了黄山松年轮生长的特点.求算不同年龄阶段的个体年轮生长的时间模型,建立年轮指数,通过与各相关气候因子的逐步回归,最终获得黄山松年轮指数与气候因子的相关方程,为研究黄山松的生长及建立黄山地区气候的历史变化提供了基础资料.分析表明,黄山地区黄山松具有较宽范围的年轮敏感度(MS).其年轮生长模型揭示,影响直径生长主要因子是生长当年>10℃积温期间的太阳辐射,其次为积温,与降水量无显著相关性;当年4月份的气候因子与年轮生长有显著相关关系.年轮生长与当年4、7月的辐射呈正相关,与当年4月平均气温呈负相关.当年4月降水与年轮生长有一定关系,但其相关性不十分显著.
The growth of Pinus taiwanensis individuals in the top area of Huangshan Mountain was studied, and the characteristics of growth of Pinus taiwanensis pine rings were analyzed. The time model of growth of individual rings in different age stages was calculated, and the index of annual rings was established. Through the stepwise regression with the related climatic factors, the correlation equations between the annual indices of Pinus taiwanensis and climatic factors were finally obtained. The establishment of Huangshan climate change history provides the basic information. Analysis shows that Huangshan pine has a wide range of annual ring sensitivity (MS). The annual growth model revealed that the main factor affecting the diameter growth was the solar radiation during the accumulated temperature> 10 ℃ in the year of growing, followed by the accumulated temperature, which had no significant correlation with the precipitation. There was a significant correlation between the climatic factors and the growth of annual rings in April . The growth of annual rings was positively correlated with the radiation in April and July of that year, and negatively correlated with the average temperature in April of that year. In April of that year precipitation had a certain relationship with the growth of annual rings, but its correlation was not very significant.
