The optimal allocation of land use in Guangzhou city was carried out by a linear planning model with multi-objective under the restriction of economic and ecological efficiency. The results indicated that optimal land-use pattern could meet the demands of land use for different departments while the plan to be implemented up to 2020. Currently, the quantitative limitation of land resources exerts tremendous stress on regional land use. The key problem lies in the contradiction between built-up land and agricultural land, especially farmland, in Guangzhou. Potential appraisal model of land use was used to assess the land-use system. The results showed that land-use system tends to be in a highly harmonious status, indicating that the potential of regional development could be lower. On the other hand, the urban land-use system would have no enough space for further development, but it could be improved by optimizing structure allocation. The optimal land-use pattern is the basis for regional sustainable development, and the integrated development among urban areas, suburban areas and industries is the major way to obtain a high regional land-use efficiency.
