Fig. 2: Spatial patterns of vegetation dynamics and resilience change in 2000–2020, 2000–2010, and 2011–2020.
From: Vegetation resilience does not increase consistently with greening in China’s Loess Plateau

a–c Spatial map of the temporal trend in kNDVI values. Positive kNDVI Kendall τ values suggest an increase in kNDVI values and thus greening, and negative kNDVI Kendall τ values suggest browning. d–f Spatial map of the temporal trend of AR(1) values. Positive AR(1) Kendall τ values suggest a decline in resilience, and negative AR(1) Kendall τ values suggest an increase in resilience. Grid cells with non-significant Kendall τ (P > 0.05) were not included in the figures for visual purposes.
