In this study an urban development model has been developed based on system dynamics, in order to compare four urban layout patterns, in terms of their effects on landscape ecology risk and environmental pollution. The four patterns are: centralised urban model, green corridor urban model, decentralised urban model (satellite city model) and resource-based city model. Landscape ecology risk assessments based on simulation results show that: the decentralised urban model is superior to the
