摘　　要：城市拓展SLEUTH模型是基于元胞自动机的城市增长模型和土地利用/土地覆盖模型的集成,通过对2003-2011年间国内外SLEUTH模型相关文献的研究,指出对SLEUTH模型的研究主要集中在模型的评价与应用两个方面;从模型模拟准确性、可移植性、与其他模型耦合、校准、尺度敏感性五个方面进行模型评价;整理并总结了模型在城市拓展、土地利用演化等方面的应用。提出目前模型研究存在的主要问题:SLEUTH模型涉及的研究区域多为大、中尺度,结果粗糙,实用性不明显;模型模拟出的结果对城市人口、经济、环境的影响还需要通过相关的指标模型进行动态验证;模型运行所需空间分辨率、模型校准所需参数的配置方法并未统一;未充分考虑社会、经济、政治等人为驱动因素和突发状况对城市扩展过程的影响。Urban growth SLEUTH model is based on the urban growth model (UGM) and Land-Use and Land-Cover Change model (LUCC) of the cellular automata model.Through arranging and researching related articles at home and abroad from 2003 to 2011,the paper points out that the research which relates to SLEUTH model include two sides:one is model evaluation,and the other is the application of model.Aspects of the evaluation are accuracy of the simulation,portability,coupling with other models,calibration and scale susceptibility.Aspects of the application include urban growth and land use evolution.Based on the literature review,the paper presents main problems of research.These problems related to the study area which is mostly studied from the large scale and moderate scale,and the research shows the result is rough and lack of practical significance.The effect of simulative results on urban population, economy,and environment still need to do dynamic verification by some relevant index model.Space resolution ratio needed by Model operation and rational parameter setup needed by model calibration are not unitary.The paper neglects the effects of human driving factors such as social,economic and political factors and also emergencies on the urban growth process.
