城市空间扩张是复杂的社会经济进程,伴随着人口、政策和城市要素向外推进等现象,是评判城市化水平的重要指标。元胞自动机(Cellular Automata, CA)是可以模拟事物发展演化过程的系统动力学模型,可以有效揭示城市空间扩张过程的特征和机制,具有广阔的应用前景。根据Geo-CA的内涵与特征,以湖南省衡阳市为例,考虑城市空间扩张的主要影响因素,本文提出了多因素制约的城市空间扩张过程元胞自动机模拟模型(Multi-factors Constrained Expanding Simulation CA, MCES-CA)。结合多期LANDSET影像、DEM和规划数据等数据源,论文构建并实现了MCES-CA模型,取得了较好的模拟结果。经检验,MCES-CA的模拟精度总体...

Urban Expansion (UE) is a critical parameter to examine urbanization level. In fact, UE is often accompanied with people, strategies, and urban elements extending over the old edge of city. Hence, UE is a highly complex socioeconomic phenomenon. Dynamic models are very effective to reveal the features and mechanisms of UE. In particular, Cellular Automata (CA) is one of the kinetic models to simulate the natural evolution process and famous for its broad range of applications. A large amount of research findings argue that CA is one of the most...
