Tree-ring samples from Chinese Pine (Pinus tabulaeformis Carr.) collected at Mt. Shimen on the western Loess Plateau, China, were used to reconstruct the mean May-July temperature during AD 1630-2011. The regression model explained 48% of the adjusted variance in the instrumentally observed mean May-July temperature. The reconstruction revealed significant temperature variations at interannual to decadal scales. Cool periods observed in the reconstruction coincided with reduced solar activities. The reconstructed temperature matched well with two other tree-ring based temperature reconstructions conducted on the northern slope of the Qinling Mountains (on the southern margin of the Loess Plateau of China) for both annual and decadal scales. In addition, this study agreed well with several series derived from different proxies. This reconstruction improves upon the sparse network of high-resolution paleoclimatic records for the western Loess Plateau, China.
在中国黄土高原西部的石门山采集的油松（Pinus tabulaeformis Carr.）年轮样本，被用于重建公元1630 - 2011年5 - 7月的平均温度。该回归模型解释了仪器观测到的5 - 7月平均温度中48%的调整方差。重建结果揭示了年际到年代际尺度上显著的温度变化。重建中观测到的冷期与太阳活动减弱相吻合。在年尺度和年代际尺度上，重建温度与在中国黄土高原南缘秦岭北坡进行的另外两个基于年轮的温度重建结果都匹配良好。此外，本研究与几个来自不同代理指标的序列结果也高度一致。这一重建改进了中国黄土高原西部高分辨率古气候记录稀疏的状况。
