Abstract: Land resources optimal allocation is one of the most challenging issues in land science field.Houlcuer the current optimal land use models have many deficiencies.We propose the land use optimal allocation model based on multi-object planning(MOP) and cellular automata(CA).Furthermore,Jiayu City was taken as an example to evaluate the model and to compare it with other models.The result shows that the integrated model based on MOP-CA has a better simulating effect.This integrated model realizs the unification of the quantitative structure and the spatial configuration optimal.
