青岛城市外部空间形态演变特征研究

Research on the Evolution Characteristics of the External Spatial Form of Qingdao

滨海城市受到海洋空间的限制,城市发展演化呈现出自身独有的规律特征,本文通过研究1987年、1999年、2012年以及2018年的4个不同时期的Landsat卫星遥感影像数据并基于ArcGIS技术平台,分析了青岛市过去30年城市外部空间的形态特征,并探究了城市发展演化的作用机理。结果显示:从城市外部形态的角度出发,青岛市在总体发展状态较为稳定的情况下,城市的演变同时受到自然地理条件的限制与区域发展趋势的推动,整体环湾发展,与外围区县相接形成区域共同体,对空间的占据能力不断提升。同时,自然地理因素、经济产业迁移、交通设施要素共同构成了青岛市空间形态演变的驱动力。

As the coastal city is restricted by the ocean space,the rule of urban development evolution presents its unique features.This paper studies the Landsat satellite remote sensing image data of 4 different periods in 1987,1999,2012 and 2018,and analyses spatial morphological characteristics of Qingdao in the past three decades based on the ArcGIS technology platform,and then explores the evolution mechanism of urban development.The results show that from the perspective of the external shape of the city,the evolution of Qingdao is simultaneously driven by the constraints of natural geographical conditions and regional development trends with the overall development status of the city relatively stable.The city develops surrounding the ocean bay,and connects with peripheral districts and counties to form a regional community,and its occupying capacity of the space is constantly improved.At the same time,natural geographical factors,economic and social factors,traffic factors constitute the driving force for the spatial form evolution of Qingdao.
