奋勇争先，决战决胜“十四五”|“三北”工程建设取得新进展

Core Viewpoint - The "Three-North" project aims to combat desertification and enhance ecological security in China, with significant progress reported in recent years, including the completion of 3.17 million hectares of construction tasks since the 14th Five-Year Plan began [1][3]. Group 1: Project Progress and Achievements - As of June 2023, the "Three-North" project has completed construction tasks covering 3.17 million hectares, with 1.9 million hectares achieved since the launch of the major battles against desertification [1]. - A total of 415 projects have been implemented under the "Three-North" initiative, marking important milestones in ecological restoration efforts [1]. - The project has seen a significant increase in biodiversity, with the population of swans in the Uliangsu Wetland rising from 200 to nearly 600 due to improved ecological conditions [3]. Group 2: Innovative Techniques and Technologies - The introduction of new technologies, such as the "grass grid + artificial blue algae crust" method, has reduced the time required for biological soil crust formation from 15-20 years to just 1-2 years, enhancing the effectiveness of desertification control [4]. - The use of advanced techniques, including intelligent drip irrigation and photovoltaic power generation, has been integrated into the project to improve vegetation survival rates [2][4]. - The "Three-North" project has achieved over 70% usage of superior tree and grass species, with nearly 50% of afforestation efforts utilizing mechanical methods [4]. Group 3: Systematic and Regional Management - The project emphasizes a systematic approach to desertification control, coordinating efforts across various ecological systems, including forests, grasslands, wetlands, and deserts, covering a total of 7.4 million hectares [3]. - Ten key areas have been designated for integrated management, promoting a collaborative governance model to address desertification challenges [3]. - The project aims to create a new pattern of regional integrated governance, focusing on both the sources and pathways of sand movement [3].
