Abstract:The urban hydrological spatial system is closely related to flood and waterlogging disaster, therefore affects the city's ecological security directly. How to plan and organize the urban hydrological spatial system with scientific and ecological methods is an unavoidable problem, so that we can prevent flood and waterlogging disaster. We should fully take different aspects into account, like coordination between spatial form and stormwater management, following the distribution law of the original hydrological space and how to deal with the relationship among water, land and city. This paper puts forward the principle of protection of urban hydrological space system and analysis of the urban design strategies combined with hydrological control in an intensive way.
