摘要
以位于长江三角洲核心区域、太湖平原东岸的苏州市为研究对象,以2007年和2017年两个时相的Landsat影像及其相关的辅助统计资料为主要数据源,结合地理信息系统和遥感技术,分析研究区域苏州市及其下辖4个县级市近10年来城市建设用地扩张的时空分异规律,并据此探索城镇空间扩张的驱动因子,为土地资源合理利用、区域可持续发展及政策制定等提供决策依据。
This paper focuses on Suzhou City, which is in the core area of the Yangtze River Delta and on the eastern bank of the Taihu Plain.The Landsat imagery and its associated supporting statistical data for the two phases of 2007 and 2017 are the main data sources, combined with geographic information systems and remote sensing technology, analyze and study the spatial-temporal differentiation law of urban construction land expansion in Suzhou City and its four county-level cities in the past 10 years, and explore the driving factors of urban space expansion in order to rationally utilize land resources.Sustainable development and policy development provide the basis for decision making.
