Research on multi-object forecasting of the reasonable population scope in Shanghai city
关于上海市人口合理规模的多目标预测研究

According to the conditions of Shanghai, this study forecasts the population scope of Shanghai using the possibility-satisfaction degree method of system engineering. The reasonable population scope in the year 2050 is given and the conditions that the scope relies on are pointed out as well. The sensitivity analysis is carried out for key influence factors: It is concluded that if more weights are assigned to virescence, water, and houses in ecological environment, resources, and social life, then this leads to constraining the reasonable population scope and to reducing the possibility-satisfaction degree. So, attention to these factors should be emphasized in order to mend the development pace of Shanghai.
