摘要

本文旨在通过统一碳排放核算内容,明确碳减排效益、碳减排效果、碳固存之间的关系,建立更加标准化、规范化的海绵城市碳排放核算模型,以评价海绵城市建设的碳减排成果和机制。基于碳排放因子法的生命周期评估(LCA)碳排放核算模型,选取甘肃省天水市某新建住宅小区作为案例,研究了海绵城市建设的碳减排效果。结果表明,新建居住区海绵城市建设 30 年全生命周期的碳排放量为 828.98 吨,而传统建设的二氧化碳减排量为 744.28 吨,碳减排率为 47.31%。在 30 年的生命周期内,总碳减排效果相当于 1460.31 吨。此外,在典型年份的各种降雨情景下,海绵城市建设的碳减排效果超过了碳排放量,在运行 22 至 30 年内实现了碳中和。这表明海绵城市社区的碳减排效果显著。该研究结果为中国海绵城市的低碳建设提供了数据和理论依据。

Carbon Emission Accounting and Reduction Evaluation in Sponge City Residential Areas
This paper aims to establish a more standardized and regulated carbon emission accounting model for sponge cities by unifying the accounting content for carbon emissions and clarifying the relationships between carbon reduction benefits, carbon reduction effects, and carbon sequestration, in order to evaluate the carbon reduction outcomes and mechanisms of sponge city construction. Based on a Life Cycle Assessment (LCA) carbon emission accounting model using the carbon emission factor method, a newly constructed residential area in Tianshui City, Gansu Province, was selected as a case study, and the carbon emission reduction effect of sponge city construction was then investigated. Results indicated that the 30-year full life cycle carbon emissions for sponge city construction in the newly constructed residential area amounted to 828.98 tons, compared to 744.28 tons of CO2 reduction in traditional construction, representing a 47.31% reduction in carbon emissions. Over a 30-year life cycle, this equated to a total carbon emission reduction effect of 1460.31 tons. Additionally, under various rainfall scenarios in a typical year, the carbon emission reduction effect of sponge city construction exceeded the carbon emissions, achieving carbon neutrality within 22 to 30 years of operation. This demonstrates that the carbon emission reduction effect of sponge city communities is significant. The findings of this study provide data and a theoretical basis for the low-carbon construction of sponge cities in China.

期刊介绍: Water (ISSN 2073-4441) is an international and cross-disciplinary scholarly journal covering all aspects of water including water science and technology, and the hydrology, ecology and management of water resources. It publishes regular research papers, critical reviews and short communications, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
