The spatio-temporal variations of regional ecosystem health and vigor showed high similarity (Fig 8). Regions with high values were mainly distributed in the northeast, south and southwest, and the northwest presented low values. Meanwhile, the values of vigor and EHI of all the regions exhibited upward over time other than the central and eastern regions (Fig 8a, 8d). Moreover, the northwest and central regions demonstrated the highest ecosystem organization levels, followed by the southwest, north and northeast, while the eastern and southern regions had weaker ecosystem organization (Fig 8b). In addition, ecosystem resilience did not change drastically among regions during the study period (Fig 8c). The south was much higher than other regions with a value of 0.8. The southwest exhibited higher resilience with a value around 0.7, and the values of the northwest were the lowest, which was below 0.45.
