（活力中国调研行）从“沙进人退”到“路进沙退”：内蒙古穿沙公路的治沙智慧

Core Insights - The article discusses the transformation of desert management in Inner Mongolia, highlighting the construction of the Bayin-Pugebu sand-crossing road as a new approach to ecological restoration and livelihood improvement [1][2]. Group 1: Project Overview - The newly built Bayin-Pugebu sand-crossing road spans 16.81 kilometers, effectively dividing the continuous sand dunes and establishing a governance model characterized by "road delineation, road-based sand control, road advancement, and road-driven economic growth" [1]. - The road serves as a "green artery" for local ecological restoration and improvement of living conditions [1]. Group 2: Ecological and Economic Impact - The road not only enhances transportation but also facilitates ecological projects, such as solar energy initiatives, by providing easier access for equipment transportation [2]. - The local government plans to implement an additional 55 kilometers of "road-based sand control" projects by 2025, building on the 544 kilometers of existing sand-crossing roads that have already contributed to the ecological management of nearly 490,000 acres [5]. Group 3: Historical Context and Future Plans - The model of "road-based sand control" has evolved from decades of experience in desert management, starting with the first sand-crossing road built in 1997 [5]. - By 2030, Inner Mongolia aims to construct or upgrade over 6,300 kilometers of sand-crossing roads, which is expected to facilitate the management of 12 million acres of sandy land [5]. Group 4: Technological Advancements - The success of the "road-based sand control" approach is supported by years of technological development in desertification management, including a comprehensive sand prevention system established during the construction of the Baolan Railway [7][8]. - The ongoing innovation in technology aims to provide replicable and scalable solutions for desertification management both nationally and globally [8].
