Fig. 2: Changes in ecosystem sensitivity index (ESI).
From: Ecosystems in China have become more sensitive to changes in water demand since 2001
a Distribution of ESI trends. We changed the windows from 7 years to 13 years to test the robustness of ESI trends to the choice of window length. b ESI trends for different biomes. The trend was calculated from the Kendall coefficient between the ESI and time series. Positive values represent increasing trends, and negative values represent decreasing trends. A total of 61.28% of the areas of interest showed a significant increasing trend (p < 0.05). The red points refer to the mean values. c Proportions of positive trends in vegetation sensitivity (Kendall test, p < 0.05) across drylands and humid regions. Abbreviations of biomes and sensitivity please see Fig. 1.
