摘要
建设海绵城市是城市面源污染控制和内涝防治的重要手段,在我国已进入全域推广阶段.为量化海绵城市源头设施在施工建设和运行阶段产生的环境和经济影响,针对目前国内外海绵城市源头设施生命周期环境(life cycle assessment,LCA)与生命周期经济(life cycle costing,LCC)集成量化评价研究存在的不足,选取某学校内场地5种典型海绵城市源头设施,采用LCA-LCC集成评价方法,量化分析不同源头设施的环境影响、环境效益、经济影响和经济成本,并识别关键影响因子.结果表明,源头设施施工建设阶段会产生较大环境影响与经济成本,运行阶段会产生较大环境与经济效益.运行阶段对径流水量和水质控制所产生的总环境影响回收期在8年以内,总经济成本回收期在2年以内,总体效益可观.
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.
