土地利用空间格局演化多智能体仿真

Multi Agent Simulation of Land Use Spatial Pattern Evolution

针对单个智能体无法完整描述空间格局变化的问题,为了准确模拟土地利用空间格局演化规律,在土地利用空间格局演化模拟中引入多智能体系统,提出一种新的土地利用空间格局演化模拟方法。采用多智能体系统描述土地利用系统,通过五元组描述土地利用智能体,并给出多智能体系统的建模流程。充分考虑居民智能体、房地产商智能体以及政府智能体的决策行为和相互作用,模拟分析土地利用空间格局演化特征,实现土地利用空间格局演化模拟。实验结果表明,所提方法的模拟结果与实际格局演化情况的拟合度较高,Kappa系数较高,说明模拟结果符合实际情况,具有一定的可信度。

In order to accurately simulate the evolution law of spatial pattern of land use, a multi-agent system was introduced into the simulation. In this paper, a new method of simulating the evolution of the spatial pattern of land use was presented. Firstly, the land use system was described by a multi-agent system, and then land use agent was described by quintuple. Secondly, the modeling process of multi-agent system was shown. After the decision-making behavior and interaction of resident agents, real estate agents and government agents were fully considered, the evolution characteristics of the spatial pattern of land use were simulated and analyzed. Finally, the simulation on the evolution of spatial pattern of land use was completed. Experimental results show that the simulation results of the proposed method have a higher goodness of fit with the actual pattern evolution. In addition, Kappa coefficient is high, indicating that the simulation result is more realistic and credible.
