摘要

In this study an urban development model was 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 centralized urban model, green corridor urban model, decentralized urban model (satellite city model), and resource-based city model. Landscape ecology risk assessments based on simulation results show that the decentralized urban model is superior to the centralized urban model in terms of long-term landscape ecological development and environmental protection. The study also analyzed the relationships between the patch spacing index and the evaluation index. (C) 2016 American Society of Civil Engineers.
