在长时间序列高分辨率LandsatTM/MSS数据的支持下,对北京地区1975~1997年城市化基本过程和驱动机制进行了分析研究。基本结论如下：(1) 北京地区城市化过程主要表现为中心大区和边缘次级中心区的面状城市化、中心大区和边缘次级中心区之间沿交通干线的线状城市化以及中心大区与边缘次级中心区之间的点状城市化3种基本模式,其中,中心大区在城市边缘区的面状城市化过程在区域内居于优势地位。(2) 北京地区城市化过程和城市格局的形成是地形、交通等内在适应性因素和经济因素、政府行为、文化传统、突发事件等外在驱动因素共同作用的结果。其中,城市规划、产业发展政策等政府行为和3000年城市发展形成的旧有城市格局和古都风貌从根本上决定了现代北京城市发展的基本过程。

Urbanization has become one of the most important methods for human to change the earth. The paper analyzes the process and mechanism of urbanization in the past two decades. Based on the analysis, three models are further explored. The first one is the polygon urbanization of the central city and the sub-central cities; the second one is the line urbanization along the major roads between the central city and the sub-central cities; the third one is the point urbanization with the non-urban land between the central city and the sub-central cities. Of them, the polygon urbanization of the central city held the leading position, while after the 1990s, the point urbanization developed very fast, causing the patch density of the urban land increase. The expansion of urban land and the formation of the regional city pattern are the result of the collective effects between the exogenous driving forces, such as population, economic policy and so on, and the internal suitable factors, such as traffic condition, locations, landforms, etc. Of them, the government behavior, such as urban planning and industrial policy, and the existing city pattern and traditional culture developed during the past 3000 years has exerted more important impacts than others on development process of this modern city.
