摘要:

利用树木年代学中的树木年轮方法,分析了六盘山地区油松的径向生长与气候要素的关系,发现研究区油松的径向生长与该地区4—5月份平均相对湿度之间存在显著的正相关关系。在响应分析的基础上,重建了1900年以来六盘山地区4—5月份平均相对湿度变化序列,重建方程的稳定性较好,相关系数达到0557。分析结果表明:重建的六盘山地区4—5月份平均相对湿度序列存在较显著的4~7年的变化周期;1900年以来,存在4个比较明显的气候较干旱的时期,分别是1905—1916年,1918—1932年,1941—1946年和1955—1962年;同时存在4个气候相对湿润的时期,分别是1900—1904年,1934—1939年,1948—1953年和1964—1973年。其中,最严重的两次干旱期分别为1905—1915年及1922—1932年。

Abstract:

ean relative humidity from April to May was estimated based on tree ring width data of Pinus tabulaeformis from 1900 onwards in the Liupan Mountains area. The radial growth of Pinus tabulaeformis in this region was significantly affected by the mean relative humidity in spring. On the basis of response analysis, the mean relative humidity changing succession from April to May was reconstructed, and the reconstruction equation was of good stability with correlation coefficient of 0557. As indicated by the spectral analysis, the reconstructed series displays significant cycles of 4-7 years. Its clear that there are four relatively dry periods: 1905-1916, 1918-1932, 1941-1946 and 1955-1962, and four relatively wet periods: 1900-1904, 1934-1939, 1948-1953 and 1964-1973. The most dry periods are 1905-1915 and 1922-1932.
