福清市城镇空间扩展规律及其驱动机制分析

Spatial Expansion of Urban/Town in Fuqing and Its Driving Force Analysis

福清市是福建省沿海经济发达的城市。特别是上世纪 90年代以来 ,福清市的经济得到快速发展 ,其经济结构已由以农业为主逐渐转向以工业为主。随着经济的进一步发展 ,福清市的城市化水平有了稳步的提高 ,其城镇用地也发生了很大的变化。城市扩展的空间数据是评估城市化进程的一个重要指标。因此 ,综合应用遥感和地理信息系统技术分别提取了福清市 1 991年和 1 996年的城镇用地信息 ,并发现在这 5年中福清市城镇用地面积增加了 1 .2倍。经过对城市区域扩展进行空间分析 ,并结合社会经济统计数据 ,推断福清市城镇用地扩展的驱动力主要为工业大发展 (工业区的成片建设 )

Fuqing is one of the cities in the coastal zonal areas of Fujian province, showing the fastest economic growth. The rapid economic development, especially in the 1990s, has resulted in the change of economic structure of Fuqing from agriculture dominant to industry dominant. With this significant economic shift, the area of urban/town land use has also increased. In essence, urban expansion in which non\|urban land use changes to urban land use is one aspect of urbanization. To reveal the actual change of this land use type, remote sensing technology was employed, which extracted the urban/town land use information from two Landsat TM images of 1991 and 1996, respectively. The study indicates that the urban/town land use of Fuqing has grown by 16.17 km\+2 during the five years, 1.2 times more than its original area in 1991. Obviously, the value of urban/town expansion is an important index, which is valuable for the assessment of urbanization. The achieved spatial data of urban/town expansion were integrated with the socio\|economic data through a GIS. This finally reveals that the driving forces to the urban/town land use expansion in Fuqing were the rapid industry development during the period.
