本研究选取中国东部浙江省省会城市杭州作为个案研究。基于时间序列Landsat MSS/TM/ETM +影像和历史普查数据，利用遥感（RS）和地理信息系统（GIS）技术和统计方法的综合方法，分析了1978 - 2008年土地利用动态、建设用地扩展模式和潜在驱动力之间的关系。结果表明，杭州都市圈建设用地的快速扩张导致土地利用转换加速。建设用地由1978年的319.3平方公里增加到2008年的862.5平方公里。1991年以前，上海城市群建设用地的扩展模式基本上是以原城区为中心的轴向扩展。1996年和2001年，原城区和两个邻近城市发生了两次重大的行政区划调整。成功地实施了“沿着钱塘江跨越式发展”和“跨钱塘江南进”战略。在空间上，前城区与两个相邻城市之间建立了更密切的联系。因此，钱塘江沿岸基础设施、设施、集约化工业园区和城乡居民点的快速发展，导致建设用地向东、向南扩展。沿着。因此，从1991年到2008年，城市扩张模式导致了多核模式。此外，详细分析表明，建设用地的增长模式是高度相关的社会经济因素，包括国内生产总值（GDP），人均可支配收入，人口增长，工业化和城市化进程，这是占主导地位的驱动因素，建设用地的时空格局的HMA。
In this study, Hangzhou, the capital city of Zhejiang Province in eastern China was selected as a case study. Based on time series Landsat MSS/TM/ETM + imagery and historical census data, analysis of the relationship between land use dynamics, built-up land expansion patterns, and underlying driving forces from 1978 to 2008 was performed, using an integrated approach of remote sensing (RS) and geographic information system (GIS) techniques and statistical methods. The results showed that rapid expansion of built-up land in the Hangzhou Metropolitan Area (HMA) led to accelerated land use conversion. The built-up land increased from 319.3 km2in 1978 to 862.5 km2in 2008. Expansion patterns of built-up land in the HMA were essentially characterized by axial expansion centered on the former city proper before 1991. In 1996 and 2001, two significant administrative division adjustments for the former city proper and two neighboring municipalities occurred. This led to the success in implementing strategies of “frog-leaping development along the Qiantang River” and “crossing the Qiantang River and developing southward”. Spatially, a closer linkage between the former city proper and two neighboring municipalities was established. Consequently, rapid development of infrastructures, facilities, intensive industrial parks, and urban and rural settlements along the Qiantang River resulted in the eastward and southward expansion of built-up land. Thus, from 1991 to 2008 the model of urban expansion resulted in a multi-nuclei pattern. Furthermore, as shown with detailed analysis, the growth pattern of built-up land of the HMA is highly correlated with socio-economic factors, including the gross domestic product (GDP), per capita disposable income, population growth, and processes of industrialization and urbanization, which represent the dominant driving factors for spatiotemporal patterns of built-up land in the HMA.
