摘要: 基于Landsat影像数据,利用遥感和GIS技术获取了武汉城市群地区3个阶段(1980—1990、 1990—2000、 2000—2010年) 的城镇用地信息,采用城镇扩展指数和城镇扩展模型分析了城镇用地扩展的时空格局、 过程及其驱动力。结果表明:①武汉城市群城镇用地空间迅速扩张,三个时段内的城镇扩展强度指数依次为0.073 2、 0.028 9和0.099 3,呈现显著的阶段性与波动性特征;②城镇用地扩展格局具有明显的空间集中性,主要表现为以武汉为扩展中心的圈层状形态,沿武汉三环、 京广线等交通干道的轴带分布形态,不同阶段的扩展格局各具特质;③城镇用地扩展呈现"一核四带"、 "一核一带"和"三核六带"的空间扩展轨迹,与经济发展的阶段性具有明显的耦合关系;④经济体制改革、 国家非均衡发展战略、 "两型"社会建设以及长江黄金水道、 京广大动脉等交通干道建设是武汉城市群地区城镇用地变化的主要驱动因素,但各时期的主导驱动机制有所差别。

Abstract: As industrialization and urbanization accelerates, urban land expansions of many urban built-up areas in middle-western region are obvious. It is significant to obtain accurate information and analyze urban expansion process and its driving force. Based on Landsat TM, ETM+, MSS imagery data, this paper obtained the urban land use information of the three stages (1980-1990, 1990-2000 and 2000-2010) in Wuhan Urban Agglomeration with the application of remote sensing and GIS technology. Furthermore, the paper analyzed the temporal and spatial patterns of urban expansion, the expansion process and its driving force of Wuhan Urban Agglomeration using the urban expansion index and urban expansion model. The main conclusions are as follows: Firstly, the urban land of Wuhan Urban Agglomeration areas have experiencing a rapid expansion process; urban expansion intensity index in the mentioned three periods were 0.0732, 0.0289 and 0.0993 respectively, showing a significant fluctuation characteristics. Secondly, the spatial pattern of urban land use in Wuhan Urban Agglomeration was emerging conspicuous concentration during the study period; Wuhan was the center of the ring-layered expansion patterns. Moreover, the urban land-use expansion relatively centralized along the directions represented by the Third-Ring Road in Wuhan, Beijing-Guangzhou Railway and other transportation corridors. The urban expansion pattern was different in different stages. Thirdly, the expansion process of Wuhan Urban Agglomeration had formed one pole and four belts, one pole and one belt, three poles and six belts during 1980-1990, 1990-2000, 2000-2010 respectively. Fourthly, it was worth noting the fact that economic reform, national non-balanced development strategy, resource-saving and environment-friendly society building, and the Yangtze River, Beijing-Guangzhou Railway and other major transport arteries were the main driving factors for urban land use change. However, the dominant driving mechanism was different in different stages.

Key words: urban land, expansion differentiation index, expansion poles and belts, Wuhan Urban Agglomeration
