Abstract: The strictest water resources management (SWRM) policy is an important policy to promote the rational use of water resources and sustainable water development in China. An evaluation of the SWRM policy is conducive to the SWRM's optimization and water governance. The S-CAD (Subjectivity – Consistency, Adequacy, Dependency) method is used to assess the implementation effect and formulation of the SWRM policy. The results show that the SWRM policy has a clear logic, goals, and strategy; the goals reflect the gov… Show more

The water-draw and utilization assessment (WDUA) policy is crucial for ensuring sustainable water development and good water governance in China. It consists of the WDUA in construction projects (WDUA-CP) and WDUA in urban planning (WDUA-UP). Based on a systematic review of the WDUA policy's development, this study evaluated the WDUA policy from the perspectives of policy text and implementation effectiveness using text-mining and statistical analysis methods. The results show that the WDUA policy is generally successful and has progressed across all regions in China. Despite existing regional gaps, effectiveness will continue to grow at the current situation of implementation. This study broadens the field of inquiry into China's water policy, enhances the method for assessing global water policy, and offers a fresh viewpoint for the international water community to understand China's integrated water resources management and water governance.

Water shortages are serious in northwest China due to the level of social and economic development, engineering, resource shortages, and other factors being restricted, so the conflict between supply and demand for water resources is prominent in different regions and different water use sectors. Therefore, Pingliang City was selected as the research object in this study. The membership function was introduced, and an interactive algorithm to correct model parameters based on the fairness constraint was derived. An uncertain multi-objective fuzzy programming model was also established. The results show that the optimal allocation of water will be 38,051.9~40,740 × 104 m3 and 39,938.4~41,317.5 × 104 m3 under a normal year (p = 50%) and a dry year (p = 75%) in 2025, respectively, and the corresponding water shortage rates will be 4.2% and 6.7%. In 2035, the optimal water allocation will be 45,644.1~49,245.9 × 104 m3 and 46,442.4~50,044.2 × 104 m3 and the water shortage rates will be 7.0% and 7.0%, respectively. The proportion of groundwater supply will decrease by 8.8% and 13.8% in 2025 and 2035 after the optimal allocation, the proportion of surface water supply will increase by 9.6% and 12.2%, and the proportion of reclaimed water will increase by −0.78% and 2.1%, respectively. The results can provide a technical reference for the development and utilization of water resources in other cities and similar areas in semi-arid regions.
