Multi-scenario Simulation of Sustainable Development in Nanchang City Based on SD Model
With the help of the principles and methods of system dynamics,this paper constructs the evaluation model of sustainable development of Nanchang city,which includes five subsystems:e-conomy,society,resources,environment and policy to simulate the changing situation and charac-teristics of sustainable development under different development scenarios in Nanchang,so as to pro-vide reference for its sustainable development decision-making.The results show that by 2030,the urban comprehensive sustainability of Nanchang shows an upward trend,but the sustainable growth of resource utilization and eco-environment subsystem increased slowly.The comprehensive coordi-nation scenario model is a better choice for the future development of Nanchang city.In the future,by taking high-quality development as the guidance,adjusting the industrial structure,increasing R&D investment,improving the level of resource utilization,strengthening eco-environmental pro-tection and comprehensive renovation,it can greatly promote the sustainable development of Nan-chang city under the comprehensive and coordinated scenario.
