Short Summary

This study analyzed MODIS NDVI data in Gansu Province from 2000 to 2022 to understand vegetation dynamics, finding a significant overall increase driven more by human activities than climate change, though their synergistic effect was dominant.

Objective

• To analyze the spatiotemporal variations in vegetation (NDVI) in Gansu Province from 2000 to 2022 and attribute these changes to the relative and synergistic effects of climate change and human activities.

Study Configuration

• Spatial Scale: Gansu Province, China
• Temporal Scale: 2000 to 2022 (23 years)

Methodology and Data

• Models used: Trend analysis, partial correlation, residual regression, geographical detector modeling.
• Data sources: MODIS NDVI data.

Main Results

• The growing-season NDVI in Gansu Province showed a significant increasing trend overall, with an average rate of 0.0029 per year (p < 0.05).
• Both NDVI values and their increasing rates exhibited a spatial pattern of "higher in the southeast and lower in the northwest"; 49.47% of the province's area showed an extremely significant increasing trend in NDVI (p < 0.01).
• Future projections indicate that the area ratio of regions with improved NDVI to those with degraded NDVI in Gansu Province will be approximately 45.5%:54.5%.
• The contribution rate of human activities to spatiotemporal NDVI variations was higher than that of climate change, but the synergistic effect of both factors was greater than their individual effects.
• Precipitation and solar radiation were identified as the two primary climatic factors influencing NDVI variations, while human activities played a crucial regulatory role in mediating climate–vegetation interactions.

Contributions

• Quantifies the spatiotemporal dynamics of vegetation in Gansu Province over a recent extended period (2000-2022).
• Provides a comprehensive assessment of the relative contributions and synergistic effects of climate change and human activities on vegetation dynamics in an arid/semi-arid region.
• Identifies key climatic drivers (precipitation, solar radiation) and highlights the regulatory role of human activities.
• Offers future projections of NDVI improvement versus degradation areas, providing a basis for proactive ecological management and restoration strategies.
