城市空间扩展是衡量城市化进程的重要指标。本文以闽南金三角地区的福建省漳州市主城区作为研究区,选取2000、2006和2013年的Landsat遥感影像,利用IBI建筑指数分别提取了3个年份的建筑用地信息,然后对其变化进行GIS分析。结果表明,13 a间漳州市主城区面积净增13.69 km2,净增面积为2000年的66.9%。主城区主要沿交通主干道往西北方向呈带状和面状扩展。缓冲区分析表明,道路对主城区扩展起到很大的引导和促进作用。综合社会经济数据可知,主城区的城市扩展历程与第二产业的发展密切相关,属工业导向型的城市扩展模式。另外,城市人口的增加也起到了一定的促进作用,不同区位人口增长速率的差异,对城市扩展的方向也产生了一定的引导作用。

Urban expansion, in which the non-urban land use is converted to urban land use, is an important aspect of urbanization. Three Landsat time-series images for 2000, 2006 and 2013 of Zhangzhou city, which is located in Southern Fujian Golden Triangle Region, have been used to study the urban expansion of Zhangzhou urban area with the assistance of remote sensing and GIS technology. The index-based built-up index (IBI) was used to extract urban build-up land information of Zhangzhou from the three images. The extended urban range and expanded urban area were obtained by applying overlay analysis on the vectorized maps allocated in eight quadrants. The result indicated that during the 13-year study period, the urban built-up area of Zhangzhou had a net increase of 13.69 km2, which was 66.9% more than the area in 2000. The calculation showed that the built-up land expanded more rapidly in the period between 2000 and 2006. The urban area expanded toward the northwest direction in a planar and linear way, which was mainly along the three main traffic lines of Zhangzhou. The buffer analysis showed that the traffic line distribution had a significant impact on urban expansion. Driving force analysis indicated that the fast economic development and population increase were the driving forces to the expansion of Zhangzhou urban area. Socio-economic data showed that Zhangzhou´s urban expansion was closely related to the growth rate of the city´s secondary industry. Its expansion pattern belonged to the industry oriented expansion. Besides, the different growth rates of population in different regions also played an important role in Zhangzhou urban area growth, which resulted in the expansion of urban area toward the north-west district. Overall, the imbalanced growth ratio between urban land area and population implied the irrational urban land development in this city. The urban expansion derived by industrial development can be represented with a traditional urban-development model. Therefore, a faster development of tertiary industry for Zhangzhou is crucial to improve the city´s developing quality. Nevertheless, when shifting the planning focus from industrial structure to tertiary industry, the decision makers should pay attention to the intelligent use of urban land.
