Sensitivity of tree growth to temperature in the southeastern China and the potential for spatial temperature reconstruction

Presented by Dr. Jiangfeng SHI on 15 May 2013 from 11:20 to 11:40
Type: Oral Presentation
Track: Dendroclimatology

Content

Tree-rings play an important role in reconstructing past temperature in high-latitude and high-elevation regions. However, little tree-ring research has been done in the subtropical southeastern China. Recent studies show that coniferous tree growth there is limited by temperatures in prior winter and the current growing season. Higher temperature in the dormant season means less damage to leaves and roots, and less consumption of previously stored carbohydrates and starches. The new temperature reconstructions match each other very well at decadal to multi-decadal scales during the past 150 years at a large spatial scale, that is, of 700 km, even though there are some discrepancies in the early part of the comparisons. Possible reasons for the discrepancies include local temperature differences, small sample depth in the early part of the reconstructions, and/or juvenile effects. Regardless, the agreements among reconstructions indicate the potential to develop a large tree-ring network to reconstruct temperature over the southeastern China.
