中文摘要：
研究了沈阳福陵油松年轮宽度变化与沈阳地区以气温为主的气候因子和1880年以来的全球气温、全球陆地和海洋温度以及北半球气温等温度变化的关系.结果表明：沈阳油松年轮宽度与全球气温变化、全球陆地和海洋温度变化和北半球气温变化有一定的相关性,而且3个大空间尺度的温度波动和沈阳当地气温对油松年轮宽度的影响较一致：冬季12、1月的气温和春季4、5月的气温对油松生长影响显著（P＜0.05）.油松年轮宽度和3个大尺度温度序列存在3～8年公共准周期变化,其19.3年和23.2年准周期可与3个大尺度温度变化均含有的20.8年的准周期对应.说明沈阳油松年轮宽度与不同尺度的温度波动呈正相关,升温变化在过去大部分时期对沈阳油松年轮生长存在积极的影响.
英文摘要：
In this paper, the correlations between the variations of Chinese pine （Pinus tabulaeformis Carr. ） tree ring width in Shenyang suburb （Fu Mausoleum） and the local temperature variables, Global Surface Air Temperature Anomaly （GSATA） from 1880 to 2004, Global Land-Ocean Temperature （GLOTI） from 1880 to 2004 and North Hemisphere Temperature Anomaly （NHTA） from 1880 to 2004 were studied. Some close correlations were detected, and the local temperature variables, GSATA, GLOTI and NHTA had some similar influences on the Chinese pine tree ring width. The air temperature in last winter （ December and January） and in spring （ April and May） affected the growth of Chinese pine significantly （P 〈 0. 05 ）. There existed a 3-8-year periodicity of the variation of Chinese pine tree ring width and the GSATA, GLOTI and NHTA, and the 19.3- year and 23.2-year quasi-periodicity of the variation of Chinese pine tree ring width corresponded with the 20. 8-year quasi-periodicity of GSATA, GLOTI and NHTA. This study suggested that the Chinese pine tree ring width in Shenyang Fu Mausoleum had positive correlations with global-scale temperature fluctuation, and the temperature increase in the past had a positive effect on the Chinese pine growth.
