Brief Analysis on Spatial Countermeasures for Enhancing Waterlogging Drainage Capacity with Background of Urban Renewal
In recent years,the global greenhouse effect has led to frequent occurrences of catastrophic climate,and the short-term heavy rainfall causes the urban waterlogging,which affect the urban safety.It is increasingly important to alleviate the pressure of urban flood control.The upgrading and reconstruction of drainage system are taken as an important way to solve the urban waterlogging now.But it is serious limited due to the scarcity of land resources in the existing urban areas caused by rapid development of city.Some representative problems are listed in the construction of the built urban drainage system under the background of urban renewal,such as tapping the potential of existing facilities,optimizing the operation schemes,integrating the multiple systems and the other strategies of upgrading standard and controlling pollution.The relevant experience in optimizing scheme of some drainage systems and selecting the location of rainwater facilities in the central urban area of Pudong New Area is described in order to provide reference for the location planning of drainage facilities in other cities.
