Abstract: Under the concept of ecological civilization construction, how to realize the coordinated development of the New-type urbanization and ecological environment has become a major problem need to be solved urgently. This paper selected Sichuan Province in rapid urbanization as the research object, analyzed the spatial and temporal evolution of New-type urbanization and ecological footprint in 2005-2015 by the model of gravity coupling model. The results showed that: ①The level of New-type urbanization and ecological footprint both showed a sustaining growth, but the spatial and temporal differences between them were obvious. The New-type urbanization level presented a Circle layered distribution pattern, high in the middle of the basin and reducing from inside to outside. The ecological footprint level presented a symmetrical distribution pattern, Pan(zhihua) Cheng(du) Mian(yang) as the axis, low in the northwest half and high in the southeast half ;②The gravity center of New-type urbanization continued moving northward, slightly and regularly. While the gravity center of ecological footprint shifted southward and then retreated to the north, dramatically but unregularly; ③The spatial overlap of the New-type urbanization and ecological footprint presented a fluctuation of separation and approaching, the change consistency was from opposite to convergence, and the spatial coupling trend was significant.
Key words：gravity transfer; new-type urbanization; ecological footprint; spatio-temporal differences; coupling relationship; Sichuan Province
