生命周期评估在景观工程碳足迹分析中的应用
Carbon Footprint Analysis of Landscape Engineering Based on Life Cycle Assessment:a Case Study of the Science Plaza Landscape Project at the Daxing Campus of Beijing University of Civil Engineering and Architecture
摘要
Abstract
Under the context of global climate warming and environmental degradation,the carbon footprint of landscape engineering serves as a crucial indicator for measuring greenhouse gas emissions throughout the entire life cycle of a project,playing a critical role in promoting sustainable development within the landscape architecture industry.Based on the life cycle assessment methodological framework,this study systematically defines the total direct and indirect greenhouse gas emissions(measured in CO2 equivalent)across various stages of landscape engineering,including planning,design,construction,operation and maintenance,and demolition.By identifying key sources of carbon emissions in critical phases,a targeted system of energy-saving and emission-reduction strategies is constructed.Taking the landscape project of the Science Plaza at the Daxing Campus of Beijing University of Civil Engineering and Architecture as a case study,quantitative analysis reveals that material production,transportation,and machinery energy consumption during the construction phase constitute the primary carbon sources.Measures such as adopting local materials,utilizing renewable energy,and optimizing the allocation of carbon-sequestering plants are estimated to reduce life cycle carbon emissions by 23 to 31 percents.This case provides a scientific basis for low-carbon design and operation of landscape engineering,effectively supporting the green transformation of the landscape industry and contributing to the dual carbon goals.关键词
