Seasonal Vegetation Recovery Dynamics Around North China Power Corridors

Supplementary data analyzes seasonal vegetation recovery around a 500 kV transmission corridor in North China from 2024 to 2025. It quantifies dynamics using fractional vegetation coverage (FVC), aboveground biomass (AGB), and the Shannon diversity index across three spatial zones. The study integrates MODIS and Landsat 8 imagery with meteorological data and ground validation.

Use Cases

• Analyze seasonal rhythms by comparing summer and winter values for NDVI, biomass, and the Shannon diversity index across Tower Base, Corridor, and Reference zones.
• Model climate-driven mechanisms using precipitation-season interaction data, which explained 89.4% of vegetation dynamics with a q-value of 0.82.
• Characterize spatial heterogeneity gradients by examining NDVI differences, where the Reference zone was 23%–38% higher than the Tower Base zone.
• Assess phenological shifts by evaluating the 7–10 day greening delay and 58% slower spring rate in the Tower Base Zone compared to the Reference Zone.

Strengths

• Integrates multi-source data including MODIS MOD13Q1 (250 m, 16-day), Landsat 8 (30 m), meteorological records, and ground validation.
• Quantifies recovery with three specific metrics: fractional vegetation coverage (FVC), aboveground biomass (AGB), and Shannon diversity index.
• Analysis covers a full seasonal cycle from 2024 to 2025, revealing significant rhythms like summer biomass being 9.5 times higher than winter.

Limitations

• The dataset is a 293.8 KB DOCX file, indicating it is a document summary rather than a raw, tabular dataset ready for direct computational analysis.
• Spatial scope is limited to a single 500 kV transmission corridor in North China, reducing generalizability.
• Sample data and row/column counts are unavailable, preventing assessment of dataset scale and structure.
