Study on SD model for sustainable development of resourced-based cities

Resourced-based Cities are the important base of resources, and have made great contribution to the economic development in China. However, with the continuous exploitation, resource is being exhausted. It is an important task for us to study how to develop the resourced-based cities. Each resourced-based city is a complex system composed of several subsystems such as resource, economy, environment, society, etc. Sustainable development of resourced-based cities depends on the reasonable structure and development pattern of each subsystem. In this paper, the idea of sustainable development and the method of dynamic simulation are combined. A SD model for the resourced-based city is built, and the equations for the model are written based on the systematic analysis of the structure for the resourced-based city. Used the model, the sustainable development ability is dynamic simulated.
