Abstract

Abstract

Sponge city construction is an important measure for urban non-point source pollution control and waterlogging prevention, which has been widely extended in China. To quantify the environmental and economic impacts of the construction and operation stages of sponge city source facilities, aiming at the shortcomings of the current global research on the environmental and economic benefits in sponge city, 5 typical source facilities in a school site were selected as the examples to quantitatively analyze the environmental and economic impacts and benefits and identify key influencing factors by life cycle assessment(LCA) and life cycle costing(LCC) integrated evaluation method(LCA-LCC). The results presented that the construction stage could generate high environmental impact and economic cost, while the operation stage could generate significant environmental and economic benefits. In the operational phase, the payback period of the total environmental impact on runoff and water quality control was within 8 years, and the payback period of total economic cost was within 2 years, and the overall benefits of sponge city source facilities were considerable.
