二树戒指 MXD (最大的 latewood 密度) 年表受苦 fabri 从 Gongga 山的东方斜坡被开发,并且一张地区性的年表(RC ) 基于二张 MXD 年表被建立。在三张 MXD 年表和 AugustSeptember 温度之间有重要积极关联,并且 RC 有最高的关联(r=0.733, n=48, P < 0.001 ) 与吝啬的 8 月 9 月温度。把分析基于生长气候,我们重建了为学习区域在过去的 171 年期间意味着 8 月 9 月温度。重建在时期期间解释了 53.5% 仪器的温度变化 19602007 (F=52.8, R 2 形容词 =52.4%) 。在过去的 171 年里,有 22 很温暖的年和 23 很冷的年,四个冷时期(18371842, 18841891, 18991905 和 19841989 ) 和三个温暖的时期(19661973, 19161924 和 18761881 ) 。我们的重建被另外的树验证来自包围区域和记录气候灾难事件的基于戒指的温度重建。
Two tree-ring MXD (maximum latewood density) chronologies of Abiesfabri were developed from the eastern slopes of Gongga Mountain, and a regional chronology (RC) was established based on the two MXD chronologies. There were significant positive correlations between the three MXD chronologies and August-September temperature, and the RC had the highest correlation (r=0.733, n=48, P〈0.001) with mean August-September temperature. Based on growth-climate analyses, we reconstructed mean August-September temperature during the past 171 years for the study area. The reconstruction explained 53.5% of the instrumental temperature variance during the period 1960-2007 (F=52.8, R^2 adj =52.4%). In the past 171 years, there were 22 very warm years and 23 very cold years, four cold periods (1837-1842, 1884-1891, 1899-1905 and 1984--1989) and three warm periods (1966-1973, 1916-1924 and 1876-1881). Our reconstruction was validated by other tree ring-based temperature reconstructions from the surrounding area and documented climate disaster events.
