（活力中国调研行）年阻百万吨流沙：内蒙古绿色屏障为黄河“减负”

Core Viewpoint - The ecological restoration project in the Ulan Buh section of the Yellow River has significantly reduced sand flow into the river, transforming the area into a green barrier that enhances ecological stability and local livelihoods [2][4][7]. Group 1: Ecological Restoration Efforts - The Ulan Buh section, previously known for severe sand flow, has undergone a transformation since the initiation of the ecological restoration project in 2022, which includes flattening sand dunes and planting drought-resistant trees [2][4]. - The area now boasts a vegetation coverage rate of over 84%, capable of blocking approximately 1.5 million tons of sand from entering the Yellow River annually [4]. - The project has created seven ecological restoration zones, including sand-blocking belts and irrigation-based tree areas, forming a comprehensive "sand-blocking network" [2][4]. Group 2: Economic and Social Impact - The project has not only improved ecological functions but also provided economic benefits to local farmers through participation in the construction efforts, achieving a win-win situation for both ecological and economic outcomes [4][5]. - In the neighboring Dala County, efforts to combat sand encroachment have led to an 80% governance rate of the Kubuqi Desert and a vegetation coverage rate of 58.6%, reversing the trend of "sand advancing and people retreating" [5][7]. Group 3: Broader Environmental Initiatives - The restoration efforts are part of the "Three-North Shelter Forest Program," which aims to combat sandstorms through large-scale vegetation construction across various regions in China [7]. - The initiatives are crucial for maintaining the ecological safety of the Yellow River, which is threatened by continuous sand influx, emphasizing the importance of ecological construction along the riverbanks [7].
