在东方亚洲人夏天季风区域评估标准化 降水土壤水分蒸发蒸腾损失总量索引( SPEI )和自我校准的帕尔默干旱严厉索引( scPDSI )的适用性到古气候重建，我们从 Guancen 山使用了一张194年的树戒指宽度年表，山西省，中国，分别地与 SPEI 和 scPDSI 调查它的关联。结果作为能在 Guancen 山上从树戒指宽度被重建的一个柔韧的干旱索引显示了 scPDSI。与另外的 hydroclimate 相关的系列的重要关联说明了那我们的重建在包围区域捕获了 hydroclimate 的普通变化。另外，我们的重建与季风亚洲干旱地图集(MADA ) 的附近的格子点显示出重要关联。当崭新的弄干趋势在 MADA 在过去的几十年期间存在时，它不管多么没在我们的重建或在仪器的 scPDSI/Dai-PDSI 被代表。这可以暗示 MADA 在我们的学习区域在过去的几十年期间过高估计干旱严厉；这 overestimation 被 MADA 使用的树戒指网络的不够的空间与时间的分布可能引起。因此，更多的干旱重建基于在东方亚洲的单个采样地点是必要的获得亚洲季风气候可变性的彻底的理解。

英文摘要：

To evaluate the applicability of the Standardized Precipitation-Evapotranspiration Index （SPEI） and the self-calibrated Palmer Drought Severity Index （scPDSI） to paleoclimate reconstructions in the east Asian summer monsoon region, we used a 194-year tree-ring width chronology from Guancen Mountain, Shanxi Province, China, to investigate its correlation with SPEI and scPDSI, respectively. The results indicated scPDSI as a robust drought index that could be reconstructed from tree-ring width on Guancen Mountain other hydroclimate-related Significant correlations with series illustrated that our reconstruction captured common variations of hydroclimate in the surrounding areas. Additionally, our reconstruction showed significant correlation with nearby grid points of the Monsoon Asia Drought Atlas （MADA）. However, while unprecedented drying trend existed during the past several decades in MADA, it was not represented in our reconstruction or in instrumental scPDSI/Dai-PDSI. This may imply that MADA overestimated drought severity during the past several decades in our study area; this overestimation was probably caused by an insufficient spatiotemporal distribution of the tree-ring network used by MADA. Therefore, more drought reconstructions based on individual sampling sites in eastern Asia are necessary to gain a thorough understanding of the Asian Monsoon climate variability.
