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