Abstract: Land use model plays an important role in analyzing, simulating, and predicting landscape pattern and ecological process. Taking central Liaoning urban agglomerations as a case, this paper explored the application of land use model CLUE-S in the regional planning of urban agglomerations, and, based on the analysis of the landscape pattern and the driving factors of landscape change from 1998 to 2004, the model was validated. Three planning scenarios, i.e., historic trend, ecological protection, and urban planning from 2004 to 2024, were simulated. The simulated urban area in the urban planning scenario was compared with the planning of central Liaoning urban agglomerations, and the results showed that the simulated results of CLUE-S model were more realistic than the planning one, suggesting that CLUE-S model would be a powerful technical means and scientific support in regional planning, being able to predict and assess the planning consequence.
