Summary
Non-destructive Resistograph technology reliably extracts ancient tree ring data for Pinus tabulaeformis. Temperature significantly influences radial growth, aiding ancient tree protection and climate change studies.
Area of Science:
- Dendrochronology
- Forest Ecology
- Climate Science
Background:
- Ancient tree protection necessitates non-destructive methods.
- Dendroclimatology advancements drive innovation in tree-ring research.
- Assessing ancient Pinus tabulaeformis growth requires reliable data.
Purpose of the Study:
- Evaluate the efficacy of the Resistograph for non-destructive tree-ring analysis.
- Extract and validate tree-ring width and density sequences.
- Determine climatic factors influencing ancient P. tabulaeformis growth.
Main Methods:
- Sample collection using Increment borers and Resistograph.
- Peak-valley analysis for Resistograph data filtering.
- Linear fitting and Ensemble Empirical Mode Decomposition (EEMD) for data correction.
Main Results:
- Resistograph data showed high reliability compared to Increment borers.
- Temperature is the primary factor affecting P. tabulaeformis radial growth.
- Tree ring density correlates significantly with mean maximum and minimum temperatures.
Conclusions:
- Non-destructive Resistograph technology is suitable for ancient tree-ring research.
- Climate, particularly temperature, plays a crucial role in ancient tree growth.
- Findings support enhanced protection and management strategies for ancient forests.
