| 英文摘要 | The long-term dry-wet changes in North China are of great interest because this area is a key region for industrial and agricultural production and lies at the northern edge of the East Asian monsoon. Abnormal summer rainfall here often triggers severe natural disasters such as floods and droughts, making this region a long-standing focus of scientific attention. However, the lack of long-term records of summer moisture variability has hindered a deeper understanding of the temporal and spatial dynamics of dry and wet conditions in this region. In this study, we present a 178-year (1839-2016 CE) tree-ring chronology developed from North China larch (Larix principisrupprechtii) growing in the L & uuml;liang Mountains. The tree-ring width indices correlate significantly with the JuneAugust self-calibrating Palmer Drought Severity Index (sc-PDSI), enabling the reconstruction of summer moisture variability back to 1879 CE. The reconstruction model explains 52.7 % of the variance in moisture conditions during the calibration period (1960-2016 CE). Our results reveal pronounced fluctuations between dry and wet periods over the past 138 years. Since the 1960s, the region has experienced a gradual drying trend, with the extreme droughts around the year 2000 being the most severe in the reconstruction. Compared with previous studies, our findings highlight the strong potential of North China larch for reconstructing long-term summer moisture variability in this region. |
