Impacts of Multi-Scale Landscape Pattern on Stream Water Quality

Abstract:

Water quality–landscape interaction were explored using multiple line regression in watershed, total stream corridor (200-m riparian buffer extending the entire stream length upstream of the site) and the local stream corridor (200-m riparian buffer extending 1000 m upstream of the site).The results showed that the catchment landscape characteristics appeared to have slightly greater influence on water quality than the total stream corridor and local stream corridor. The edge density of construction land and percent cultivated land had the greatest influence on water quality in watershed scale. The edge density of forest land and percent forest had the greatest influence on water quality in total stream corridor scale, but percent forest and PD had the greatest influence on water quality in the local stream corridor scale.
