Abstract:In response to the problem that the evaluation index system for green and low-carbon ship locks is neither systematic nor comprehensive,considering the characteristics of ship lock projects,this study aims to achieve resource conservation and intensive utilization,energy structure optimization,energy efficiency improvement,environmental and ecological protection,intelligent operation management,and innovative development.By employing methods such as hierarchical analysis,goal decomposition,trend analysis,and the PDCA cycle,the study systematically proposes key elements of green and low-carbon throughout the life cycle of ship lock projects,constructs an evaluation index system for green and low-carbon ship locks,and suggests methods for assigning weights to indicators,scoring,and evaluation.The index system covers 6 primary indicators including overall indicators,resource utilization and conservation,energy structure and efficiency,environmental and ecological protection,operation management,and innovative development,along with 30 secondary indicators.Among these,“innovative development” serves as a bonus indicator,while the others are regular indicators.The index system combines quantitative and qualitative approaches,possesses characteristic attributes of ship lock projects,and is systematic,scientific,operational,forward-looking,and open.It can provide guidance and reference for the green and low-carbon construction of major water transport projects both domestically and internationally.
