Population, resources, environment and economy form a complex system we called PREE system. For this system, a multi-objective model is formulated based on nonlinear goal programming. In practice, we take social development plan of Beijing as a case study. According to the targets of the 9th and 10th Five-Year Plan, the authors put forward concrete target functions by fitting the statistic data, and then get the results of those decision-making variables and target variables with the model. In the last part of the paper, the authors analyzed these results and proposed some suggestions related to public policy. The application shows that this model could provide decision support for the plan of society development.
