Soil Respiration Data from Coniferous to Broadleaved Forest Conversion Study

34.5 KB of tabular data from a two-year comparative field study on forest conversion effects on soil carbon cycling. The dataset, authored by Xin Huang and last updated in 2026, shows a 25.52% increase in total soil respiration after conversion from Pinus elliottii to Eucalyptus urophylla × E. grandis. It was collected using paired adjacent plots and continuous in-situ observations in subtropical coastal sandy lands.

Use Cases

• Modeling soil carbon turnover based on measured respiration components and temperature sensitivity (Q10).
• Analyzing the relationship between litter quality (C/N ratio, lignin content) and heterotrophic respiration rates.
• Investigating the coupling effect of fine root biomass and microbial activity on total soil respiration.
• Assessing the stability of carbon sequestration in coastal protection forests based on shifts in respiration drivers.

Strengths

• Data is based on two-year continuous in-situ observations, providing temporal depth.
• Key findings are quantified with specific percentages, such as a 272.5% increase in fine root biomass.
• The study design uses a paired adjacent plot design for comparative analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's 34.5 KB size indicates a limited scope, likely containing summary or processed results rather than raw time-series.
