| Popis: | Temperature increase would benefit tree radial growth in the high latitude permafrost zone due to the increment of the thaw depth of permafrost. Tree rings from temperature-limited regions are highly sensitive to temperature variations. Seven Dahurian larch (Larix gmelinii Rupr.) tree-ring width chronologies sampled at the permafrost zone in western Great Xing’an Mountain, Northeast China, were developed to investigate regional larch growth. A regional larch growth record was produced using the first principal component (PC1) of a principal components analysis. PC1 accounted for 65.6 % of the total variance. Regional larch growth was mainly limited by summer temperatures in this region. The temporal variations in the linear trend of average summer temperature were calculated at 30-year intervals. A significant increase trend (P |
