| 英文摘要 | China's power sector and renewable energy development have expanded rapidly, yet the construction of power generation infrastructure continues to depend heavily on carbon-intensive materials such as cement, steel, aluminum, and copper. This reliance leads to substantial embodied carbon emissions, posing challenges to the achievement of national climate targets. However, a comprehensive spatiotemporal assessment of material stocks and their associated carbon lock-in across Chinese provinces is still lacking. To address this gap, this study employs dynamic material flow analysis and embodied carbon emissions accounting to examine provincial power generation infrastructure from 1993 to 2024, and further projects future material demand and associated carbon lock-in through 2060 under multiple energy-transition scenarios. Key findings reveal a pronounced spatial heterogeneity in overall material stocks, characterized by a westhigh, east-low; north-heavy, south-light pattern. From 1993 to 2024, thermal-dominated provinces contributed over 60 % of cumulative embodied carbon emissions. Hydropower-intensive southwestern provinces are marked by cement-heavy emissions from dam construction, while wind- and solar-rich northwestern regions show rapidly growing emissions linked to aluminum used in renewable energy projects. Under accelerated energy transition scenarios, solar power infrastructure may account for up to 94 % of the national aluminum stocks within China's power infrastructure by 2060. This research offers a provincial-scale perspective on carbon lock-in in power infrastructure construction, highlights the material-mediated challenges for the decarbonization of the power sector, and provides a quantified basis for assessing embodied carbon emissions risk, thereby supporting the design of spatially differentiated policies. |
