The hydrological control of Urban water adaptive landscape facilities and its performance measure

National Natural Science Foundation of China General Programme (2017.01 - 2020.12),  Completion.

Abstract : Rapid urbanization in China over the recent decades has caused a series of ecological and environmental issues on the nation’s water systems such as irreversibly changing hydrological circulation conditions, increasing the risk of urban floods and water shortages, causing the degradation of underground water quantities and qualities, and reducing biological habitats. Based on the complexities and the comprehensiveness of issues related to hydrological ecosystems today, theories from landscape ecology, hydraulic dynamics, ecological hydraulic engineering as well as urban planning are combined into one framework to address these question. By means of mathematical and relevant experimentation, using observational data and survey data from already finished water adaptive landscape demonstration project, this project is planning to study water retaining landscape in the origin of runoff, water runoff reducing process and adaptive performance in the end of runoff from different classes and aspects, and also to study the mechanism of flood and storm water process, water purification, as well as other functions of water adaptive landscape system. Researching on existing ecological planning and projects, the project also deals with framing the method and the indications of performance evaluation of water adaptive landscape project to provide a reliable method and tool in comparing and evaluating water adaptive landscape and scenarios for the “Sponge City” planning and design.
