滨州市付家河护坡治理固碳与节能减排效益分析

Analysis of Carbon Sequestration and Energy-Saving Emission-Reduction Benefits of Slope Protection Treatment in the Fujia River in Binzhou

摘要:

以滨州市沾化区付家河综合治理工程中的草皮护坡设计为案例,基于生命周期评价(LCA)理论方法和建筑碳排放计算等有关标准规范和文献,量化核算护坡建材生产、运输、施工、运行维护、拆除处置全生命周期碳排放,系统对比草皮护坡替代混凝土护坡的碳减排与固碳效益。结果表明,20年设计使用年限内,单位面积草皮护坡净碳排放较较C30混凝土护坡降低86.9%,整个工程总减排量达476.95 t CO₂e,生态价值显著。

Abstract:

Taking the turf slope protection design in the comprehensive treatment project of the Fujia River in Zhanhua District, Binzhou Municipality as a case study, this paper quantifies and accounts for carbon emissions throughout the full life cycle, including building material production, transportation, construction, operation and maintenance, and demolition and disposal, based on the life cycle assessment (LCA) theoretical method and relevant standards, specifications, and literature on building carbon emission calculation. The carbon emission reduction and carbon sequestration benefits of turf slope protection as a substitute for concrete slope protection are systematically compared. The results show that within the 20-year design service life, the net carbon emission per unit area of turf slope protection is 86.9% lower than that of C30 concrete slope protection, and the total emission reduction of the entire project reaches 476.95 t CO₂e, demonstrating significant ecological value.
