Abstract: Based on the strategic requirements for high-quality development of water conservancy in Shaanxi during the "15th Five-Year Plan" period and closely following the development orientation of new quality productive forces, this paper systematically explores the optimization paths and practical schemes of Shaanxi's water conservancy standardization system. Aiming at the structural shortcomings existing in the current standard system, such as insufficient coordination, lagging supply in emerging fields, unbalanced enterprise participation and inefficient implementation mechanism, the study proposes to strictly align with the general architecture of the Ministry of Water Resources' "Water Conservancy Technical Standard System Table", construct a two-dimensional matrix system framework based on "professional categories" and "functional sequences", and complete the precise adaptation and dynamic improvement of content in combination with Shaanxi's local conditions. Focusing on five key areas: smart water conservancy and digital twins, river and lake management and protection, water ecological governance and restoration, intensive and economical utilization of water resources, and standardized management of major water conservancy projects, the research clarifies the specific tasks and implementation paths for standard formulation and revision, and builds a comprehensive guarantee system from four dimensions: organization, institution, talent and funding. The purpose of the study is to create a modern water conservancy technical standard system with scientific layout, clear structure and complete functions, provide solid technical support for major water conservancy projects such as the Han-to-Wei River Diversion, and promote the modernization of water governance capacity in Shaanxi.
