Constructing Landscape Ecological Security Patterns of an Ancient Capital Based on Cellular Automata Theory

Urban sprawl in developing countries changes urban land use structure and function, threatens the sustainable development of regional ecology security patterns city landscapes. A new way to control is develop a comprehensive landscape plan, analyze factors influencing growth, optimize demarcate growth boundary. Here, we Xi’an, China, as case study scenarios pattern spatial explore zoning. We construct theoretical framework manage expansion from perspective smart growth. As first step, integrated constructed based on four factors: hydrology, geological disasters, cultural heritage, recreation. Second, model simulated cellular automata model. Finally, nine land-use are developed by overlaying expansion. Thus, space divided into three types zoning scenarios: suitable construction, restricted prohibited construction. The calculations indicate that area accounted for 10.4%, 14.7%, 74.9%, respectively, total Xi’an. It great significance determine contradiction between protection process establish schema use. discuss rapid urbanization at macro scale, formulate plan balances protection.
