摘要
黄河流域水资源供需矛盾问题日益突出,全面推进非常规水源开发利用是缓解黄河流域水资源短缺的有效途径之一.根据黄河流域各省(自治区)2014-2023年水资源公报数据,统计分析了黄河流域及流域各省(自治区)非常规水源开发利用现状与趋势.结果表明:近年来黄河流域非常规水源开发利用量逐年上升,2023年达到23.14亿m3,在供水总量中占比6.10%.在非常规水源开发利用方面,存在缺乏科学规划、统计口径不一致、激励约束机制有待完善、水质未满足使用要求、管理能力有待提高等问题.建议从建立健全非常规水源利用部门协调机制、统筹将非常规水源纳入水资源统一配置、建立非常规水源利用激励约束机制、完善非常规水源利用相关技术标准、强化流域治理管理等多方面施策,协同促进非常规水源开发利用,为缓解黄河流域水资源供需矛盾、提升水安全保障能力提供有力支撑.
Abstract
The mismatch between water supply and demand in the Yellow River basin is becoming increasingly acute.Comprehensive development and utilization of unconventional water sources present an effective approach to mitigate water scarcity.Based on the 2014-2023 water resources bulletin data from provinces and autonomous regions in the Yellow River basin,this study statistically analyzes the current status and trends of unconventional water source development and utilization in the region.The findings reveal a consistent annual increase in the utilization of unconventional water sources,reaching 2.314 billion m3 in 2023,accounting for 6.10%of the total water supply.However,several challenges persist,including inadequate scientific planning,inconsistent statistical standards,insufficient incentive and constraint mechanisms,water quality failing to meet usage requirements,and limited management capacity.To address these issues,it is recommended to establish a coordinated mechanism among relevant departments,integrate unconventional water sources into unified water resource allocation,develop incentive and constraint mechanisms,refine technical standards,and strengthen river basin governance and management.These measures aim to advance the coordinated development and utilization of unconventional water sources,providing robust support to mitigate the supply-demand imbalance and enhance water security in the Yellow River basin.
