引领“三北”工程攻坚战，全国荒漠化防治标委会推荐了这21项标准

Core Viewpoint - The establishment of a standardized system for desertification prevention is crucial for the success of the "Three-North" project, providing essential technical support for this large-scale ecological initiative [1][3]. Group 1: Standardization Efforts - In 2021, China established a national technical committee for desertification prevention standardization, leading to the development of a comprehensive standard system that includes 28 standards across six categories [1]. - The standard system includes 25 industry standards and 5 national standards, with 6 industry standards and 1 national standard already published [1]. - A demand list for new standards related to the "Three-North" project has been created, suggesting the addition of five urgent standards [1]. Group 2: Application of Standards - The committee has compiled a list of 21 practical standards for frontline personnel, ensuring easy access to effective technical guidelines [2]. - New standards are set to be added by 2025, including those for photovoltaic projects and ecological impact monitoring in desert areas [2]. - Local forestry departments in key provinces are adapting national standards into actionable technical guidelines, demonstrating a multi-layered standard supply system in operation [2]. Group 3: Impact on Desertification - The "Three-North" project has successfully reduced the area of desertified and sandy land, shifting from "sand encroachment" to "green recovery" [3]. - The improved standardization framework is essential for measuring progress and ensuring scientific rigor in the project, laying a solid foundation for ecological restoration [3].
