Interrelations Between Socio-economic Development and Environmental Quality : a Simulation Integrating System Dynamics Models with GIS

System dynamics (SD) theory has long been deployed in modeling complex non- linear interrelationships but, so far it has not been common to do the kind of modeling in support of bringing environmental sustainability policies to practice. This is largely because the challenge of including spatial data has not yet been well met. Potential for adoption of SD and GIS methods in combination is exemplified with the results of a decision- support exercise designed for simulation and prediction of the dynamic inter- relationships between socio-economic development and environmental quality for the Wen, Pi, Du county in Sichuan province, southwestern China.
