3.1 Spatio-temporal evolutions of
urbanization from 2000 to
2020
EU exhibited the highest scores compared to the other subsystems, which
were above 0.03 after 2010, while SCU was the lowest, with values below
0.02 (Table 4). Moreover, the values of PU, EU, SU and UI reached their
highest in 2015, and SCU showed a steady upward trend, reaching a
maximum in 2020. For the indicators’ changes, all of UI and four
subsystems increased from 2000 to 2020 (Table 4). Among them, EU behaved
the largest value of 0.0004 and SU exhibited the lowest. Furthermore,
all indicators, apart from social urbanization, presented a negative
change rate in 2015~2020. In particular, spatial
urbanization increased by 0.001 in 2000~2005, but
decreased in 2005~2020.
