[Coupling analysis between new-type urbanization and ecological environment in Fujian Pro-vince, China.]

Identifying and revealing the coupling relationship between urbanization and ecological environment and its forming mechanism, and then putting forward regulation measures, will benefit urban management in making decisions. We examined the coupling process between new-style urbanization and ecological environment system of Fujian Province through the coupling model and coupling-coordination model, and realized the spatial visualization based on the index system of urbanization and ecological environment, in which the index weight was based on the variation coefficient. The results showed that the variation of coupling degree between new-type urbanization and ecological environment system was relatively stable, ranging from 0.77 to 0.99 during 2000 to 2015. There was no obvious difference among the cities except for the Putian in 2000 and Zhangzhou in 2010 were in the break-in stage. The coupling-coordination degree between new-type urbanization and ecological environment system fluctuated around 0.50 during 2000 to 2015 with significant spatial differentiation and shorter evolution time from east to west. The coupling-coordination types of Fujian Province were dominated by the harmonious development type, accompanied by the types of moderate unadjusted recession, moderate coordinated development, and high coordinated development. There was transformation phenomenon among different types. Xiamen was the only one deve-loped into the high coordinated development type in 2015. The city development was mainly featured by lagged urbanization, with the lagged ecological environment in Xiamen in 2010 and in both Fuzhou and Xiamen in 2015.
