Compared with medium-sized cities, megacities play an increasingly important role in the rapid urbanization process in China. Owing to the expanding scale of large cities, urban sprawl leads to unsustainable practices that cause ecological, social, and environmental problems. we can use the SLEUTH model to simulate the implementation scenarios of future urban growth.Using the scientific simulation data of the model, we contrasted the alternative futures of the two planning types(Urban planning and land use planning) for local government decision makers to achieve sustainable urban planning. China is using this model in their various provinces.The local government depends on urban planning and land use planning to manage urban growth. The urban and rural planning law is formulated to strengthen urban and rural planning administration; harmonize urban and rural spatial layout; improve people׳s living environment and promote the integrated, harmonious, and sustainable development of urban and rural society and economy. Most construction activities follow urban and rural planning. However, this situation leads to current development problems in large cities in terms of the following aspects. First, the urban planning is periodically affected by leadership changes. Second, the changing adjustment of administrative area influences the sequence of construction. Third, the management and control objectives of land use are not the same in different administrative sections. Fourth, the inflexible management system cannot adapt to the economic and social development of the expanded city.
