Based on coupling theory, first using fuzzy AHP and DEA methods, we calculated the urban land use intensity and efficiency calculation of mid-southern Liaoning urban agglomerations form 1985 to 2010, then adopted the coupling and coupling effects index for temporal and spatial analysis. Results showed that: (1) from 1987 to 2012, urban land use of mid-southern Liaoning urban agglomerations was in the basic intensive phase, city efficiency fluctuated upward trend, and coupling of the two curves showed U shape; (2) mid-southern Liaoning urban agglomerations was at stage of the conversion of the weak coupling to strong coupling,coupled distribution in the west was weaker than in the east and coupling distribution pattern exhibited in east-west direction axis, north and south symmetrical distribution, Shenyang and Dalian have become a high value dual-core, and Liaoyang, Anshan, Yingkou, Panjin are the second highest value distribution, east keeps for low value areas; (3) the change of coupling effect is largely from negative to positive effects of process, differences in eastern and western area have existed for a long time; significant changes of coupling effect occurred in 2012, it had also helped optimize the entire coordination constantly. (4) with respect to Dalian, coupling phase synchronized with coupling effect, coupling effect had promoted urban development; with respect to Shenyang, Anshan and Panjin, coupling efficiency was ahead of the coupling phase; the rest cities are at the lower coupling stage, coupling does not bring positive development dividends.
