摘要： 对黄山松80年的年轮序列中S及重金属元素Mn、Fe、Zn、Cu和Pb含量分析结果表明,年轮中S浓度可划分为3个等级:58.5%年轮段,S浓度<2mg·kg^-1;24.4%年轮段,S浓度3.65～6.0mg·kg^-1;17.1%年轮段,S浓度>11mg·kg^-1.年轮序列中S的积累有较大幅度的波动,可分为波动型(1917～1960年)、相对稳定型(1961～1980年)和持续增长型(1981年以后)3种类型;在1935～1938年、1959～1960年以及最近10年的年轮中,S含量均>11mg·kg^-1,表明该时段大气中S的浓度较高.统计分析表明,近18年来,旅游人数的增加与年轮中S含量呈显著相关性,一些景点较集中的燃料消耗可能造成局部大气污染,从而影响到树木.年轮序列中Pb的积累浓度低于土壤背景值;Mn、Fe、Zn和Cu在年轮中的积累均有明显的波动性;统计上无显著的相关性,表明这4种元素在年轮中的积累是独立的;Zn和Cu在年轮序列中积累的波动与树龄无关;Mn在年轮序列中的浓度随树龄增加而降低,在最新的几个年轮段又略有增加,Fe则相反.

Abstract: Based on the concentration analyses of S,Mn,Fe,Zn,Cu and Pb in the growth ring set of Pinus taiwanensis at the summit (1 400～1 600 m alt.) of Huangshan Mountains during past 80 years,this paper studied the dynamic characters of element concentrations in the ring set,and their relationships with atmospheric environment.The results showed that there were three levels of S concentration in the growth ring set,i.e.,low concentration (less than 2 mg·kg^-1),accounted for 58.5% of the ring set; medium (3.65～6.0 mg·kg^-1),accounted for 24.4%; and high (>11.0 mg·kg^-1),accounted for 17.1%.The dynamic change of S accumulation in the ring set displayed an obvious fluctuation,which could be divided into 3 major types,i.e.,fluctuation during 1917～1960,relatively stable during 1961～1980,and gradual increase after 1981.In the growth ring set of 1935～1938,1959～1960,and recent 10 years,the S accumulation concentrations were all higher than 11 mg·kg^-1,suggesting the relatively high atmospheric S concentration in those periods.There was a significant correlation between the increase of tourist amount in Huangshan scenic spot and the S concentration in growth ring set.The fuel fume centralized in some places might result in the atmospheric pollution at local scale,which in turn,might influence the S accumulation in growth ring set.The Pb accumulation concentration in the ring set was less than the background value in soil.The accumulation concentrations of Mn,Fe,Zn and Cu showed fluctuation characteristics,with independence of each other.The accumulation of Zn and Cu in growth rings had no correlation with tree age,while that of Mn and Fe was in adverse.The Mn concentration in the growth ring set decreased with tree age but increased in recent growth rings,while the Fe concentration was on the contrary,which needed further study.

Key words: Sulphur, Heavy metals, Concentration, Dynamic, Growth ring set, Pinus taiwanensis
