摘要
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．
This paper dealt with the tree ring growth characteristics of Pinus taiwanensis on
the top of Mt. Huangshan. Correlation functions of ring width index with climatic factors were
obtained by step by step regression, which could provide a basis for studying the growth of
Pinus taiwanensis and for constructing the historically climatic change of Huangshan region.
Tree ring growth analysis shows that the pine had a wider range of mean sensitivity of tree
ring growth. The tree ring growth model shows that the key factors affecting diameter growth
were the solar radiation at the duration of>10℃ and the accumulated temperature in current
year, with no relation to precipitation. The tree ring growth was strongly correlated with the
climatic factors in current year, positively with the radiation in April and July, and negatively
with the average temperature in April. There was no significant relationship with precipitation in
current year.
