Landscape Pattern Change of Impervious Surfaces and Its Driving Forces in Shanghai during 1965–2010

Rapid urbanization influences the landscape pattern of impervious surfaces, and potentially affects surface water quality. Using ArcGIS Fragstats, this study analyzed temporal change surfaces in Shanghai over past 45 years, its driving forces impact on quality were also analyzed. The results show that both low high showed different degrees expansion, as a result, pervious area reduced by 40.1% 13.8%, respectively. It proves fragmentation diversity notably increased decades, especially substantial changes. primary are population density, unit Gross Domestic Product (GDP), percentage industry. result Redundancy analysis (RDA) is explanatory ability to variations decreased from 68.7% 46.4% period 2000–2010. should be stressed contribution configuration variation less than surfaces.
