According to the growing characteristics of urban space, it is very great significant for urban development planning to explore the laws of urban expansion and study the calculation and prediction model of the urban growth boundary. Unfortunately, the study of developed models is little able to simulate the urban growth boundary in domestic and foreign country. This paper proposes to build an urban growth boundary model in complex geometry with the combination of artificial neural networks, geographic information systems and remote sensing technology. The model experimental results show that, with the model, the calculation and prediction accuracy of the future urban growth boundaries is up to 80%~84%, the results express intuitive and real and provide a decision-making reference for the urban planning in the current smart growing ways.%针对城市空间增长特点,探究城市扩展的规律,研究城市增长边界的计算和预测模型,这对于城市的发展规划具有重要的意义.然而,在国内外,关于城市增长边界方面的研究较少,首次提出利用人工神经网络、地理信息系统和遥感相结合的技术建立具有复杂几何形状的城市增长边界模型.通过数值实验结果表明,模型对城市未来增长边界的计算和预测准确度达80％～84％,结果表示直观、真实,能够为当前精明增长模式下的城市用地规划工作提供决策参考.
