With the theory and method of general system science, the paper, by taking Xianning City as a case study, established coupling coordination theoretical models of socio-economic benefits and eco-environment benefits of urban land intensive use, then analyzed socio-economic benefits and eco-environment benefits of urban land intensive use, coupling degree and coupling coordinative degree between urban land intensive use socio-economic and eco-environment by using the statistical data during 1999—2008. The results showed that: ①The socio-economic benefits of urban land intensive use increased rapidly, however, the eco-environment benefits of urban land intensive use increased in a fluctuation. ② In general, the coupling degrees of urban land intensive use socio-economic benefits and eco-environment benefits was at an antagonism development stage, the coupling degrees increased slowly. ③The coupling coordination degree of urban land intensive use socio-economic benefits and eco-environment benefits experienced low coordination level, moderate coordination level and high coordination level.
