Abstract As connection area of airport and city, the socio-economic-environmental development of airport zone is affected by multiple factors and changes rapidly, which makes the environmental impact assessment of its planning difficult to predict. An integrated methodology framework, including system dynamic simulation model for airport zone, parameter analogy and scenario analysis, was developed to predict and assess the socio-economic-environmental impacts of different developing modes. Specifically, the framework consists of several steps: analysis of regional development, identification of environmental impacts, model constitution, zero/planning scenario simulation, alternative scenarios design and mitigation measures, with dynamic feedbacks among steps. The Zhengzhou Airport Zone was taken as a case, and results show that planning scenario had advantages of more growth and less pollutants discharge, which were still beyond environmental capacity; 3 alternative scenarios were designed and mitigation measure such as adjustment of industrial and energy structure was proposed.
