- Abstract:
-
Wuhan Metropolitan Area was taken as a case study in this paper. The paper established evaluation indicators for land use benefits from the aspects of society, economy, ecology and environment, and analyzed land use benefits, coupling degree and coupling coordinative degree of land use benefits by using the variance coefficient-TOPSIS method and coupling coordination theoretical models. The results showed that: (1) the land use benefits had the characteristics of obviously polarized pattern and gap of regional differences. The low-level socio-economic benefits of land use with other cities was the main, and the excellent socio-economic benefits of land use with Wuhan was complementary;the good eco-environment benefits of land use with other cities was the main, and the low-level eco-environment benefits of land use benefit with Ezhou was complementary;the moderate comprehensive benefits of land use with rest of the city was the main, then the low-level comprehensive benefits of land use with Ezhou and good comprehensive benefits with Wuhan were complementary; (2) the coupling degrees of land use efficiency was in an antagonism development stage with smaller regional differences; (3) the coupling coordination degree of land use efficiency has obvious regional differences, with moderate coordination coupling level and high coordination coupling level, Wuhan was in a high coordination coupling phase, other cities were in a moderate coordination coupling phase.
