摘 要：為了落实中共中央《关于新时代推进西部大开发形成新格局的指导意见》和《关于制定国民经济和社会发展第十四个五年规划和二○三五年远景目标的建议》中明确强调的“加快形成以国内大循环为主体、国内国际双循环相互促进的新发展格局”，从系统平衡的角度，基于胡焕庸线来审视南水北调西线工程与我国东西部水土关系，通过杠杆原理论证推演了水土关系与人水关系内在逻辑的统一性，说明了南水北调西线工程对于推进西部大开发形成新格局和构建国内经济大循环的重要意义。在国土空间与经济国内大循环这一大系统中，胡焕庸线处于系统平衡点的重要位置，为解决我国东西部发展不平衡、不充分的问题，应尽快实施南水北调西线工程，使胡焕庸线这一系统平衡点西移，进而使国土空间布局中的水土关系更加协调平衡，使我国经济大系统中的人水关系在更加协调的平衡态中可持续发展。以陇中地区为例，实证说明了实施南水北调西线工程、建设“水高地低”陇中河套地区的必要性和可行性。

Abstract：In order to implement the guiding opinions of the CPC Central Committee on Guideline on Advancing the Development of Western Regions in New Era to Promote Coordinated Regional Development and Recommendations on Formulating the Fourteenth Five-Year Plan for National Economic and Social Development and the Long-Term Goals for 2035， it is clearly emphasized that accelerate the formation of a new development pattern in which the domestic big cycle is the main body and the domestic and international double cycles promote each other. From the perspective of system balance， based on the “Hu Huanyong Line” to examine the relationship between the West Route of the South-to-North Water Transfer Project and the water and soil between the east and the west of China， through the original theory of leverage and explains the importance of the West Route of the South-to-North Water Transfer Project in promoting the development of the western region and building the domestic economic cycle by analyzing the spatial layout of the territory through the relationship between water and soil and the domestic economic cycle through the relationship between human and water. “Hu Huanyong Line” is in the important position of the system balance point in the large system of land space and economic domestic circulation. In order to solve the issue of unbalanced and inadequate development between the east and the west of China， the West Route of the South-to-North Water Transfer Project should be implemented as soon as possible to make the balance point of “Hu Huanyong line” moving westward， so as to make the relationship between water and soil in the land spatial layout more coordinated and balanced and make the relationship between human and water in Chinas economic system developed sustainably in a more coordinated and balanced state. Taking Longzhong area of Gansu as an example， it demonstrated the necessity and feasibility of implementing the West Route of the South-to-North Water Transfer Project and constructing a “high water and low land” of Hetao area in Longzhong.
