南水北调工程是实现中国水资源南北调配、东西互济，形成水资源合理配置格局的战略性工程。南水北调西线一期工程已初步确定先行从长江上游的雅砻江调水40亿m³至黄河上游的洮河，经洮河至刘家峡水库后入黄河干流。本研究从南水北调西线调水新增水资源量入手，结合新提出的黄河干流甘肃段的新型水土格局（即“弦弧”两支主要输水路线下），重点对新增水资源量的利用进行思考，并分析了新型水土格局下新增调水对黄河干流甘肃段、西北内陆区石羊河流域、内蒙古阿拉善地区和宁蒙灌区等受水区的影响。研究结果有利于水资源稀缺地区输调水资源可持续合理利用，可为黄河流域上游生态保护与高质量发展的战略规划实施提供参考。

The South-to-North Water Diversion Project is a strategic project to realize the South-North allocation of water resources， the East-West mutual aid， and the formation of a rational allocation pattern of water resources in China. It has been preliminarily determined that the first phase of the west route of South-to-North Water Diversion Project will divert 4 billion cubic meters water from the Yalong River in the upper reaches of the Yangtze River to Taohe River in the upper reaches of the Yellow River， and then to the main stream of the Yellow River after passing through Taohe River to Liujiaxia Reservoir. Based on the new water and soil pattern of Gansu section of the main Yellow River （i.e.， under the two main water transport routes of "string arc" of the Gansu section of the Yellow River）， this study focuses on how to make use of the new water resources. This study also analyzed the effects of the new water and soil pattern on the Gansu section of the main stream of the Yellow River， the Shiyang River Basin in the northwest inland region， the Alxa region of Inner Mongolia and the Ning-Mongolia irrigated areas. The study are beneficial to the sustainable and rational utilization of water resources in areas with scarce water resources， and can provide a reference for the implementation of strategic planning for ecological protection and high-quality development in the upper reaches of the Yellow River Basin.
