Abstract: Taking the Ar Khorqin Banner as the research area and using the respective towns as the research units, the spatial difference of land use degree and benefit as well as the coupling degree and coordination degree were analyzed by using the land use degree comprehensive index, the comprehensive benefit index, and the model of coupling degree and coordination degree. The results showed that the land use degree of the whole banner was in a moderate state, and the average value of the comprehensive index of land use degree of the 14 towns was 203.2. The average value of land use comprehensive benefit index was 1.160, and the average value of land use economic benefit, ecological benefit and social benefit index was 0.451, 0.392 and 0.317, respectively. The spatial difference of land use benefit was great and the land use benefit increased gradually from the regional center to the periphery. The average value of the coupling degree between land use degree and benefit was 0.454, showing antagonism on the whole, and the average value of the coordination degree was 0.308, showing moderate coordination on the whole. The towns with high coordination degree and coupling degree between land use degree and benefit were mostly grassland and areas with animal husbandry as the supporting industry.
