Abstract:

The development trend of geographical science indicates that the research on urbanization and ecological environment coupling will move from quantitative description to dynamic simulation. At present, the dynamic simulation models of urbanization and ecological environment coupling are diverse. This article reviewed and summarized four common types of models, including system dynamics model, artificial intelligence algorithm, land use change model, and composite model. The main conclusions are as follows: 1) System dynamics models are widely used in the dynamic simulation of urban complex nonlinear systems, urban transition and sustainable development, and urbanization and ecological environment elements coupling. However, spatial interpretation is insufficient and system adaptability is ignored. 2) Artificial intelligence algorithm has significant advantages in simulating self-learning, self-organizing, and adaptive systems, as well as uncertain systems. It is applied to identify urban expansion, environmental change, resource demand, and ecological vulnerability, but the application range is narrow. 3) Land use change models are limited to the simulation of urbanization and ecological environment coupling under the condition of land transfer to urban use. 4) To achieve complementarities between the various models, it has become a trend to develop composite models based on multi-model integration. In the future, we should develop dynamic simulation models from both the technical and theoretical aspects, and strengthen the simulation of microscopic processes.
