Abstract: Taking Karamay City of Xinjiang as the research object, the comprehensive evaluation index, relative development degree and coupling coordination degree of land use benefit and urbanization were calculated by establishing the evaluation index system of land use benefit and urbanization, and the coupling coordination development relationship between them was studied. The results showed that, from 2006 to 2018, the land use benefit indices of Karamay City increased year by year, and the urbanization indices showed a change trend of “fluctuating increasing and stabilizing”. The comprehensive index of land use benefit and the comprehensive level of urbanization increased significantly, and the relative development degree was “lagging, leading, lagging” type of land use benefit; the coupling degree had changed from the low-level coupling stage in 2006—2015 to the antagonistic stage in 2016—2018, and the land use benefit and urbanization coupling condition had gradually developed in the direction of run-in; the degree of coupling coordination increased year by year and went through three stages： dissonance recession, transition coordination and moderate coordination. The type of coupling coordination changed from high incoordination to intermediate coordination.

Key words: land use efficiency, urbanization, entropy value method, coupling coordination, Karamay City
