Fig. 5: Relationships between cropland landscape configuration and agricultural input intensities.

MPA, PD, and AI represent Mean Patch Area, Patch Density, and Aggregation Index, respectively. The scatter plots illustrate the relationships between landscape metrics (MPA, PD, and AI) and Fertilizer Intensity (t t⁻¹), Mechanization Intensity (kW t⁻¹), and Irrigation Intensity (m³ t⁻¹). Red (contraction period, 2000–2015) and green (recovery period, 2015–2020) data points and dashed lines indicate the provincial-level observations (31 provinces across different years) and corresponding linear regression fits. Shaded bands around the regression lines indicate the 95% confidence intervals.
