摘要：Urban metabolism provides a robust framework for analyzing urban development and its ***,several conceptual and operational shortcomings have constrained the application of urban metabolism in understanding the overall urban processes,limiting the transfer of its potential benefits to design and *** article systematically analysed the rationale of the current urban metabolism models,focusing on four prevailing shortcomings from a transdisciplinary perspective:1)utilizing an isolated state approach,which treats urban systems as isolated from other ecosystems;2)ignoring internal processes within urban systems,known as the black box paradox;3)employing a linear material approach that focuses on the path of single materials;and 4)overlooking the material productivity of urban systems,where energy and materials entering the system are used to reproduce the urban material structure and generate goods and tradable *** these issues have been identified individually in existing scientific literature,there is a lack of holistic *** article proposes an enhanced urban metabolism analytical approachDthe ecosystem approach applying atechnomassoDto address these shortcomings and provide practical solutions in landscape architecture and planning disciplines for sustainable urban development.
