福清市城市时空扩展的遥感监测及其动力机制

Remote Sensing Monitor and Driving Forces Analyses of Urban Expansion for Fuqing City, SE China

采用遥感 (RS)和地理信息系统 (GIS)一体化技术 ,以福清市为例 ,对城市时空扩展进行动态监测和模拟 ,并结合区域社会经济统计数据 ,展开城市扩展特征分布和动力机制分析 .结果表明 ,福清市城市扩展速度与区域经济发展和外资的投入有着密切的相关 .此外 ,交通建设、经济投资区的建设和当地的自然地理环境对城市的扩展速度和方向也起着重要的作用 .

Integrated RS and GIS technology was used to dynamic monitor and simulate the urban expansion process of Fuqing City, which lies in the southeast of Fujian Province. Driving forces to urban expansion were analyzed using socioeconomic data. The study reveals that the rapid urban expansion resulted from the economic development and the foreign capital. In addition, the traffic construction, economic investment districts and natural geographic environment are also contributed to the urban expansion.
