摘　　要：为了研究城市化过程中规划政策和关键区位对于城市空间形态扩张和功能结构调整的带动作用,以吉林省延吉市为例,基于触媒理论,通过未来土地利用模拟模型和景观扩张指数,探索规划政策的修改对未来城市形态发展的影响,诊断城市扩张方式。结果表明:规划政策修改前城市形态紧凑度低,出现离心型城市化的现象;规划政策修改后,新机场作为新的城市触媒更好地连接新老城区,城市空间结构优化,城市形态紧凑度提高。城市触媒对城市形态的优化作用,需要利用良好的空间规划政策。在现行规划政策付诸实施之前,FLUS模型能对未来结果以及开发选择进行评估。In order to study the driving effect of planning policies and key locations in the process of urbanization on the expansion of urban spatial form and adjustment of functional structure,taking Yanji city,Jilin province as an example,based on the catalyst theory,the future land use simulation and the landscape expansion index were used to explore the impact of the modification of planning policies on the development of future urban morphology and diagnose the way of urban expansion.The results show that before modifying planning policies,urban form had low compactness and urbanization is centrifugal.After modification,the relocated airport become an urban catalyst,better connecting new and old urban areas,optimizing urban spatial structure,and increasing urban form compactness.The role of urban catalysts in optimizing urban forms requires the use of sound spatial planning policies.Before the current planning policies are implemented,the FLUS model can evaluate future results and development options.
