英文摘要	Long records of tree-ring maximum latewood density (MXD) measurements in conifers have been successfully employed to reconstruct summer temperature changes globally. Yet, the potential of MXD as a proxy in semi-arid, low-latitude regions for reconstructing either temperature or hydroclimate variability remains largely unexplored. Here, we developed a MXD data set of Chinese pine from semi-arid northern China, and investigated its sensitivity to different climate variables. We found that the annual self-calibrated Palmer Drought Severity Index from previous August to current July displays the strongest influence on the MXD variation. The entire MXD chronology (covering 1736-2020) is highly consistent with nearby tree-ring-based annual precipitation and drought reconstructions at decadal timescales, confirming a temporally stable hydroclimate signal in our MXD record. In particular, the rapid wetting trend during the 2010-2020 period is well captured by the MXD data. This novel study has wide implications for future use of tree-ring density data to reconstruct past climate changes globally.
