摘要：

To promote the sustainable development of reclaimed water utilization, this study focuses on reclaimed water use in Changxing County, Zhejiang Province, China. Based on the United Nations Sustainable Development Goals (SDGs) framework, an evaluation index system for reclaimed water utilization benefits was developed. The Analytic Hierarchy Process (AHP) and Entropy Weight Method (EWM) were used to determine weights, and the Grey Relational Analysis Model was employed to assess the benefits. The results indicate that reclaimed water utilization is closely related to four SDGs (SDG 6, SDG 8, SDG 9, SDG 12) and their eleven specific targets (e.g., SDG 6.3, SDG 6.4, SDG 6.5). The index system includes five criteria and 25 indicators. Between 2015 and 2022, the benefits of reclaimed water utilization in Changxing County have steadily increased, divided into three periods: Initiation Exploration (2015-2016), Steady Improvement (2017-2019), and Good Performance (2020-2022). Indicators requiring the most improvement include Water stress level, Unconventional water use rate in industrial production, and Fiscal input ratio. Improvement suggestions include implementing diversified measures to alleviate water stress, increasing industrial water use rates, and enhancing policy mechanisms to support sustainable water resource management.
