Ecohydrology and good urban design for urban storm water-logging in Beijing, China

摘要

Urban storm water-logging (USWL) is a worldwide problem. To address this problem in Beijing, its effects and causes were analyzed. Among others, the causes include increasing impervious surfaces and climate change. Considering the limitations of current approaches, the need for a more sustainable approach - ecohydrology (EH) - was identified. Thus concepts of EH and good urban design (GUD) were introduced and a framework of systematic EH solution with GUD, utilizing best management practices (BMPs) and source control principle, was proposed. The idea of applying a combination of EH methods with GUD was explained. This approach was expected to eliminate USWL problems, harvest stormwater and create other benefits as well. In addition, several helpful tools, models and systems (TMS) were described.
