摘要
本文以咸阳市为例,借助三期Landsat遥感数据,运用Erdas和Arcgis软件平台对咸阳市的建成区边界进行提取,并结合咸阳市的社会经济统计数据对咸阳市的空间扩张方向和驱动力作了时空分析。结果表明:咸阳市2010年比1988年建成区面积扩张3.35倍;通过人口、经济和交通因素3方面对建成区驱动力进行分析,发现经济因素是其驱动力的核心因素。
A case study was conducted in Xianyang city, Shaanxi Province. According to the three periods remote sensing images, using Erdas and Arcgis 9. 3 to draw the border of the built-up area, combining with social and economic statistical data of Xianyang city to analyze its direction of special expansion and dynamic monitoring. The results showed that the buih-up area of Xianyang in 1988 was 3.35 times as large as its in 2010; by using population, economy and traffic factors to analyze the driving force of the built-up area, it was found that economy is the core factor.
