为在复杂水资源系统中实现多水源协同配置与精准调度,缓解西北内陆河流域缺水地区供需矛盾,以典型资源型缺水的金昌市为例,考虑不同外调水规模与地下水管控策略,设计了6种方案,在构建水资源供需网络模拟模型的基础上,系统模拟了规划年2030年各方案的水资源供需态势。结果表明:引大入秦延伸增效工程调入1.10亿m³水量时,可基本保障市区工业用水需求;引大济西工程调入1.26亿m³水量时,市区生活与工业用水可完全满足,并可置换部分用于农业灌溉的地下水。据此提出争取引大入秦延伸增效工程供水指标、积极推进引大济西工程、加快灌区现代化改造与高标准农田建设等对策建议。

To achieve coordinated allocation and precise regulation of multiple water sources within complex water resources systems, and to alleviate the supply-demand contradiction in water-scarce regions of inland river basins in Northwest China, this study took Jinchang City, a typical water-scarce city, as a case study. Considering different amounts of inter-basin transferred water and groundwater control strategies, six schemes were designed. Based on a simulation model of water supply and demand, the water supply and demand situation under each scheme for the target year 2030 was systematically simulated. The results indicate that when the Yin-Da-Ru-Qin Project supplies 110 million m³ of water, the industrial water demand in the urban area can be largely met. When the Yin-Da-Ji-Xi Project provides 126 million m³, the domestic and industrial water demands in the urban area can be fully satisfied, and some groundwater originally used for agricultural irrigation can be replaced by the transferred water. Accordingly, countermeasures and suggestions are proposed, including striving for water allocation quotas from the Yin-Da-Ru-Qin Project, actively promoting the Yin-Da-Ji-Xi Project, and accelerating the modernization of irrigation areas and the construction of high-standard farmland.
