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.
