英文摘要	As water-related ecosystem services (WRES) encounter unprecedented threats with climate change and human activities, it is important to understand the impact of variations in the supply and demand for WRES on Sustainable Development Goals (SDGs). Previous studies commonly overlooked water quality and water-use sectors when using comprehensive supply-demand index (SDIcom), defined as the difference between water supply and demand, leading to challenges in applying WRES estimation to SDGs assessment. We constructed a refined supply-demand framework for WRES, categorizing the water supply by water quality and the water demand by sectors. It allows the calculation of refined supply-demand index (SDIref), addressing the limitations of SDIcom. Our findings demonstrate that SDIref could be effectively employed to assess SDGs and rectify the overestimation of SDIcom in the case study in Xinjiang. The supply-demand relationship of water resources indicates surpluses in domestic and industrial water use and deficits in agricultural and ecological water use, with the latter worsening. SDIref is projected to be higher in the scenario with SSP2-4.5 and high growth rate of irrigation efficiency. Our study suggested informed decisions based on SDG-specific targets to either maintain or enhance SDG progress scores. The proposed refined supply-demand framework of WRES established a quantitative link between WRES and human well-being, providing applicable insights for other ecosystem service assessments in other regions. The study on the supply and demand of water-related ecosystem services (WRES) describes the process of WRES transmission from water-related ecosystems to human society. The variations in these transmissions arising from internal differences in water quality and water-use sectors are pivotal factors in the effects of WRES to Sustainable Development Goals (SDGs). Unfortunately, these critical factors were generally neglected. Based on above-mentioned gap, we proposed a refined supply-demand framework of WRES, introducing the refined supply-demand index (SDIref). SDIref, which accounts for water quality in supply and water-use sectors in demand, exhibits superior performance in SDGs assessment. In the case study of Xinjiang, SDIref could more accurately capture the supply-demand relationship of water resources compared to the comprehensive supply-demand index (SDIcom) that is the difference between water supply without considering quality and demand without sectors. Domestic and industrial water resources are projected to be in surplus and agricultural and ecological water resources will face worsening deficit. The most sustainable water supply-demand relationship is anticipated in the scenario with moderate greenhouse gas emissions and a high growth rate of irrigation efficiency. In light of the specific SDG assessment, we posed appropriate recommendations aimed at improving SDG progress scores. This study could offer valuable insights for integrating WRES into decision-making towards enhancing human well-being. This study proposed a refined supply-demand framework for ecosystem services to assess the Sustainable Development Goals The refined supply-demand index could provide more accurate assessments on ecosystem services compared to the comprehensive supply-demand index The relationship between water supply and demand in Xinjiang will undergo a worsening deficit in the future
