| The accelerating of urbanization has changed the hydrological condition of land,so that exacerbating the flood disaster and water quality..Meanwhile,traditional engineering methods cannot cope with these increasing rain-flood problems by drainage and flood-control.In order to facilitate the construction of China’s Sponge City,improve the rain-flood management in large and medium-sized cities,solve problems about water pollution and urban waterlogging.There firstly analyzing the important ecological functions of urban wetland landscape in China’s Sponge City construction,then,puts forward the strategies of rainwater management and water quality improvement.To realize the functions of improving ecological environment,promoting landscape effct and alleviating city waterlogging,also achieving the total control rate of inside-and-outside regional rainwater.Furthermore,to achieve the target of reducing water pollutant discharges,solve the situation of malodorous black water,and construct seasonal rainwater landscape.Thus,there reforms the Ecological Wetland Park to urban landscape where both have functional and ornamental value. |
