Chinese Fagaceae Forest GPP Drivers with Climate and Age Thresholds

A supplementary research file analyzing gross primary productivity (GPP) in Chinese forests dominated by Fagaceae species. The data likely contains results from variance decomposition, structural equation modeling, and regression analyses identifying climate and forest characteristics as primary drivers. The file, authored by Shaowei Yang and last updated in April 2026, is shared under a CC-BY-4.0 license.

Use Cases

• Modeling carbon sequestration potential based on forest genus and climate zone classifications mentioned in the description.
• Identifying critical forest age thresholds for productivity based on the reported peaks at 90.40 and 91.00 years.
• Analyzing the relative influence of climate versus forest characteristics on GPP based on the reported variance contributions (56.83–81.29% and 8.06–23.58%).
• Comparing GPP values across taxonomic genera (e.g., Castanopsis vs. Quercus) and climate zones (e.g., south subtropical vs. north temperate) using the provided high and low examples (6553.5 and 1300.9 g C m⁻² yr⁻¹).

Strengths

• Includes specific GPP values for different forest genera and climate zones, such as 6553.5 g C m⁻² yr⁻¹ for Castanopsis and 1300.9 g C m⁻² yr⁻¹ for Quercus.
• Quantifies the percentage contribution of different driver categories (climate: 56.83–81.29%, forest characteristics: 8.06–23.58%).
• Identifies precise critical age thresholds for GPP, such as 90.40 years in the middle temperate zone.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document (2.5 MB), which may require extraction or conversion for analysis.
