Model set and validation set data for biomass modeling from a four-year paired field experiment in the southern Ningxia loess hilly region, China. The experiment replanted Amygdalus davidiana after removing a 28-year-old Caragana korshinskii plantation and compared it with adjacent natural A. davidiana woodland. Aboveground biomass was estimated with a species-specific allometric model calibrated with 260 destructively sampled branches and independently validated with 45 branches.
Use Cases
- Calibrating species-specific allometric models for Amygdalus davidiana based on destructively sampled branch data.
- Validating biomass estimation models using an independent set of sampled branches.
- Comparing biomass dynamics between replanted and natural woodlands in a paired experimental design.
- Studying the ecological impact of replacing Caragana korshinskii plantations with Amygdalus davidiana.
Strengths
- Model calibration is based on 260 destructively sampled branches.
- Includes an independent validation set of 45 branches.
- Data originates from a four-year paired field experiment, suggesting controlled comparison.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the specific loess hilly region of southern Ningxia, China.
