Change with Water——The Rational Cognition of Sponge City System from the Perspective of Urban Green Space System
HU Nan;LI Xiong;GE Xiao-yu;
In November 2014, the Sponge City System(SCS)—Low Impact Development(LID) system was proposed based on foreign practical experience and our national conditions as well to explore healthy development pattern for the city. LID differs from traditional stormwater management system on construction goals, carriers and techniques. Urban Green Space System(UGSS), as an important carrier and main basis of SCS, will get higher requirement from SCS planning results in return. Although they direct mutually in the process of planning, SCS and UGSS still have differences in structure layout. UGSS plays a supporting role in SCS and urban green space of different types functions differently. Under guidance of SCS, UGSS should be controlled reasonably in construction direction and strength. Keeping rational recognition of SCS, as prerequisite of co-adaption between city development and natural hydrology and avoidance of its blind development, promotes sustainable development of human habitats consequently, especially amidst of over-active exploring SCS construction.
