摘要：Landscape ecological pattern mode emphasized the control and influence of landscape space pattern on the process, and through the change of pattern, it could preserve the health and safety of landscape function flow. The study methods of landscape ecological pattern included static analysis and dynamic analysis. Establishing integrated ecological infrastructure by utilizing ecological security pattern methods was the basis for urban ecological environment planning, which provided theoretical foundation and practicable means for ecological city construction, and which could be applied in the analysis of basic characteristics of urban landscape ecology and current status of urban landscape security pattern, and in the planning of urban landscape ecological pattern. By taking Xi'an City for example, it could analyze eco-environment and composition of landscape ecological pattern in Xi'an by adopting static analysis. It had concluded the distribution and features of ecological bases, corridors and patches in Xi'an. Meanwhile, it had made a summarization of fragmentation of base pattern, artificialization of corridors, and decentralization of patches at built up areas, hoping to provide theoretical basis for researches and completion of ecological pattern in Xi'an City.
