The Control of Land-Use Patterns for Stormwater Management at Multiple Spatial Scales

摘要: While most research about the relationship between land use and watershed hydrological output has focused primarily on land-use types their impact processes, characteristics of patterns (such as pattern fragmentation, connectivity, coherence) processes not been well examined. Using historical stormwater data, this study evaluates effects different scenarios in Qing-shui Beijing, China, at a variety spatial scales. This demonstrates that planning managing can significantly reduce runoff under scales, particularly for small storm events. In contrast to other aspects structure characteristics, such shape complexity patches, fragmented level patches appear dominant drivers runoff. The results suggest management should be an important component Best Management Practices impacts urbanization natural processes.
