摘要

The microclimate in the Kashmir Valley varies significantly from west to east due to abrupt elevation changes caused by the Pir Panjal Range (PPR) in the west and the Zanskar Mountain ranges in the east. We developed tree-ring chronologies of Abies pindrow (Royle ex D. Don) Royle from the adjacent valleys of Gulmarg and Kupwara within the PPR, covering the periods 1603–2003 and 1567–2015 CE, respectively. Using local and Srinagar meteorological records, we investigated the climate variability within the PPR on tree growth to derive tree growth-climate relationships. Our results show that temperature primarily influences tree growth in the Gulmarg Valley, while precipitation is the main driver in the Kupwara Valley. Despite variations in the magnitude of these correlations, the climate-growth relationship for Kupwara remains consistent whether local or Srinagar meteorological records are used. However, for the Gulmarg Valley, the use of local versus Srinagar meteorological records results in contrasting growth-climate relationships. This discrepancy is attributed to the distinct geomorphological features—such as location, elevation, and shape—that create varied climatic conditions across each valley of the PPR. Our findings highlight the high sensitivity of tree growth to local microclimates. For a more accurate understanding of the tree growth-climate relationship of A. pindrow and for studying past climatic variations in the Himalayan region, it is crucial to use local climate data for calibrating and verifying tree-ring-based reconstructions of climatic parameters rather than relying solely on data from geographically distant stations.
