| 摘 要： | 基于多期Landsat遥感影像,提取渭南市主城区的建成区数据,结合GIS分析功能,定量分析了渭南建成区的扩展面积和扩展速度,计算了城市重心和扩展方向.结果表明,近年来（1994～2013年）渭南建成区的面积和扩展速度都显著增加,并达到一个相对高的稳定值;随着城市西部高新区的建设,城市重心移动的主基调是由东向西移动,市政府搬迁规划的实施以及各个重大项目的兴建,使其有向北扩展的步态.

| Abstract: | Based on Landsat remote sensing images in many stages, the built-up area data of Weinan were extracted. Combined with GIS anal- ysis, the expansion area and rate of built-up areas in Weinan were quantitatively analyzed. The city center and urban expansion direction were calculated. The results showed that the area and expansion rate of built-up areas in Weinan during 1994 - 2013 significantly increased and reached a relatively high stable value. City center was moving from east to west with the construction of high-tech zones. The implementation of municipal government relocation plan and the construction of various major projects made the northward movement. |
