| 摘要: | 20世紀中葉後，人類經濟活動和能源使用量成為二氧化碳排放的主要原因，雖然2020年受疫情影響導致全球二氧化碳排放下降，但2021年又大幅上升。2015年巴黎協定（Paris Agreement）通過，以2100年全球平均升溫控制在2℃之內為目標；因此截止至今，全球已有142個國家提出淨零排放（Net Zero）之目標。臺灣也於2022年發布「臺灣2050淨零排放路徑及策略總說明」，提出「能源、產業、生活、社會」四大轉型與「十二項關鍵戰略」，其中又以「運具電動化及無碳化」及「淨零綠生活」兩項推動人本綠運輸之概念來完備自行車環境，如自行車友善行駛空間、公共自行車站點與通勤自行車道系統等，以提供安全及便利的自行車環境，促進民眾增加其使用並達成減碳目標。而臺北市配合永續發展理念，於2009年設立公共自行車系統（YouBike），將臺北市公共自行車定位為公共運具中第一哩及最後一哩的低碳轉乘運具之一，並持續建構市區自行車道路網。本研究以臺北市為例，重現其歷年自行車路網時空分佈，以及臺北市公共自行車站點分佈位置狀況，並透過騎乘自行車可以有效減少二氧化碳排放量之計算方式及空間分析方法，分析臺北市公共自行車之使用相較於不同運具所減少的二氧化碳排放情形，以作為相關單位規劃自行車路網或佈設臺北市公共自行車站點之依據。根據2016年至2023年之YouBike對比各運具二氧化碳排放量的時空分析結果，都以大安區為減碳最多之行政區，且以燃油汽車被取代之減碳成效最佳，而2023年公共自行車租借量與二氧化碳減量與人口密度、土地使用分區及自行車周邊路網都具一定相關性。
In the latter half of the 20th century, human economic activity and energy use became the main causes of carbon dioxide emissions. Although global carbon dioxide emissions declined in 2020 due to the pandemic, they rose sharply again in 2021. The Paris Agreement was passed in 2015 with the goal of keeping the global average temperature rise to within 2°C by 2100. As of now, 142 countries worldwide have proposed Net Zero targets. Taiwan also released the "Taiwan 2050 Net Zero Emission Path and Strategy General Description" in 2022, proposing "energy, industry, life, society" four major transformations and "twelve key strategies". Among them, "vehicle electrification and decarbonization" and "net zero green life" are two concepts to promote people-centered green transportation to improve the cycling environment, such as bicycle-friendly driving spaces, public bicycle stations, and commuting bicycle lane systems, etc., to provide a safe and convenient cycling environment, encourage people to increase their use and achieve carbon reduction goals. In line with the concept of sustainable development, Taipei City established the public bicycle system (YouBike) in 2009, positioning Taipei City's public bicycles as one of the low-carbon transfer vehicles for the first and last miles of public transportation, and continuously constructing the city's bicycle road network. This study takes Taipei City as an example, reproduces its annual bicycle road network spatio-temporal distribution, and the distribution of Taipei City public bicycle stations, and through the calculation method of effectively reducing carbon dioxide emissions by riding bicycles and spatial analysis methods, analyzes the carbon dioxide emissions reduced by the use of Taipei City public bicycles compared to different vehicles, as a basis for relevant units to plan bicycle road networks or set up Taipei City public bicycle stations. According to the spatio-temporal analysis results of YouBike's comparison of carbon dioxide emissions from various vehicles from 2016 to 2023, Daan District is the administrative district with the most carbon reduction, and the carbon reduction effect of gasoline cars being replaced is the best. The rental volume of public bicycles and the reduction of carbon dioxide are related to population density, land use zoning, and the surrounding road network of bicycles in 2023. |
