摘　　要：水资源作为基础性的自然资源和战略资源,已逐渐成为限制地区经济社会持续稳定发展的控制性因素。为贯彻落实把水资源作为最大的刚性约束要求,实现粤西苦旱地区水资源最大化的合理开发利用,以环北部湾广东水资源配置工程为例,在分析工程受水区2012-2020年用水变化趋势的基础上,采用多层次指标法、熵值法和加权平均法构建节水刚性约束评判体系,以研究工程受水区现状2020年、设计2035年的用水总量及供水端、用户端各项节水指标刚性约束程度。结果表明:环北部湾广东水资源配置工程受水区近十年用水总量和各业用水总体呈缓慢下降趋势,用水结构逐渐趋于合理,但现状2020年节水水平差,除用水总量指标外,约束层其余指标均不符合节水刚性约束要求;设计2035年节水刚性约束程度强,约束层节水指标均满足评判标准,预期层节水指标综合得分90.7、节水刚性约束等级高,工程设计符合国家、广东省的节水刚性约束要求,满足调水工程“先节水后调水”的“三先三后”首要前提,但应进一步加强居民生活节水、农业节水灌溉和高效节水灌溉相关工作。研究成果可为环北部湾广东水资源配置工程分析调水区域与对象、优化工程设计方案等提供参考,建立的节水刚性约束评判体系对类似调水工程节水分析具有借鉴意义。As a fundamental natural and strategic resource,water resources have gradually become a controlling factor limiting the sustained and stable development of regional economy and society.In order to implement water resources as the maximum rigid constraint requirement and realize the rational development and utilization of water resources maximization in the drought-stricken areas of western Guangdong,tak⁃ing Guangdong water resources allocation project around the Beibu Gulf as an example,based on an analysis of the water consumption change trend from 2012 to 2020 in the project demand area,the multi-level index method,entropy value method and weighted average meth⁃od are used to construct a rigid constraint evaluation system for water conservation,which is used to study the total water consumption and the rigid constraint degree of each water conservation index at the water supply end and the user end in 2020 and in 2035.The results show that the total water consumption and the water consumption of all industries in the demand area of Guangdong water resources allocation proj⁃ect around the Beibu Gulf in the past decade have shown a slow downward trend,and the water consumption structure has gradually become reasonable.However,the current water conservation level in 2020 is poor.Except for the total water consumption index,the other indicators of the constraint layer do not meet the requirements of rigid water conservation constraints.The design has a strong degree of water conserva⁃tion rigid constraint in 2035,and the water conservation indicators in the constraint layer meet the evaluation criteria.The comprehensive score of the water conservation indicators in the expected layer is 90.7, and the water conservation rigid constraint level is high. The projectdesign meets the national and Guangdong water conservation rigidity constraint requirements and the primary premise of“ saving water firstand then transferring water” in water transfer project. However, it should further strengthen the work relat
