Résumé partiel _ Urban area is the region where has the strongest interactions in the human-earth system.With the rapid development of large-scale urbanization,the contradiction among economic development,resource utilization,and the ecological environment has become increasingly prominent in cities.Therefore,to promote urban sustainable development,it is essential to construct the mode of urban development by integrating the resources,the ecological environment,and the economy.Urban metabolism provides a new prospective for exploring the sustainability of urban development.Urban metabolism regards the city as an organism,and the interrelationship among urban society,the economy,and the natural environment are examined in terms of resource utilization to identify the impact of the external environment on the city,which is an effective method for evaluating the utilization of resources and the problems of ecological environment in cities.Oasis city,with features of drought,diversity,closure,and vulnerability,which is a typical urban type mainly distributed in arid and semi-arid areas.The sustainable development of Oasis cities is of great importance to regional sustainable development and national security.Therefore,from the perspective of urban metabolism,exploration of the sustainability of development of cities plays significant roles in the formulation of urban development strategies and the promotion of the efficient utilization of resources.Based on the theory of urban metabolism,this dissertation constructs the analytical framework of the study of metabolism for Oasis city based on the “scale-efficiencystructure-influence” as the main research logic.This dissertation takes the typical Oasis cities in Xinjiang as examples,the metabolism characteristics and its driving factors of Oasis cities in 2002,2007,2012 and 2017 were studied by using the material flow analysis,data envelopment analysis model,input-output analysis,ecological network analysis,and the extended STIRPAT model.This study firstly analysis the changes of the scale and structure on material resources,and the status of emissions of pollutants in Oasis cities.Afterwards,the characteristics of the metabolic efficiency of material resources and their evolution modes in Oasis cities are explored.Then,this study identifies the internal relationships between various departments in the urban metabolic system.At last,this study explores the main driving factors of Oasis cities’ metabolism.
