（原标题：治沙三十载：书写"绿进沙退"生态画卷） 治沙不仅要靠技术，更要靠人。林业站构建起"生态管护员+社会管护员"的管护体系，马尚军便是社会 管护员之一。"我干了10年护林员，看着沙窝子变绿，每月2400多元的工资也让日子稳当不少。"马尚军 说，当地群众通过参与治沙、管护，不仅实现了家门口就业，更在2020年实现全部脱贫，昔日的"治沙 人"变成了"护绿人"，也成了脱贫攻坚的"受益人"。 经济观察网 据央广网报道，夏日哈镇曾是风沙肆虐的"重灾区"，过去这里是"天上无飞鸟，地上不长 草"的沙漠荒地，植被覆盖度不足5%，"沙进人退"是当地群众的共同记忆。 三十余载攻坚，夏日哈镇的治沙答卷愈发厚重：植被覆盖度从5%跃升至40%，风沙天气较往年减少近 六成；曾经的流动沙丘被草方格和林木固定，青杨、新疆杨连片成林；鹿、石羊时常在林间穿梭，"绿 进沙退"的生态图景在高原上徐徐展开。 都兰县林业和草原局项目管理室负责人王永军介绍，林业站在长达30年的防沙治沙历程中不断摸索与尝 试，最终一套"组合拳"式的沙障技术成为防沙固沙的核心利器——1.5米×1.5米的草方格沙障是基础防 线，工作人员用当年新鲜稻草，经划线、运草、铺草后 ...

Core Viewpoint - The newly constructed Bayin-Pugebu Sand Crossing Road in Inner Mongolia represents a significant advancement in desertification control, transforming the region from "sand encroachment" to "road advancement" and serving as a "green artery" for ecological restoration and livelihood improvement [1][3]. Group 1: Project Overview - The Bayin-Pugebu Sand Crossing Road spans 16.81 kilometers and effectively divides the shifting sand dunes, implementing a governance model of "road delineation, sand blockage, and economic development" [1][3]. - The road construction is part of the "Three-North" project, which employs a scientific approach to desertification control, including road construction, sand fixation, and planting drought-resistant vegetation [3][5]. Group 2: Economic and Ecological Impact - The road has not only improved the local environment but also facilitated economic opportunities, such as easier access for solar energy projects and job creation for local farmers and herders [5][7]. - The local government plans to implement an additional 55 kilometers of "road-based desertification control" projects by 2025, building on the 544 kilometers of existing sand crossing roads that have already contributed to the ecological restoration of nearly 490,000 acres [5][7]. Group 3: Technological and Scientific Foundations - The success of the "road-based desertification control" strategy is rooted in decades of accumulated experience and technological advancements in desertification management in Inner Mongolia [5][7]. - Historical innovations, such as the comprehensive sand prevention system developed during the construction of the Baolan Railway, have laid the groundwork for current practices, which aim to provide replicable solutions for desertification control both nationally and globally [7].

Core Viewpoint - The global issue of desertification significantly impacts biodiversity, ecological security, poverty alleviation, socio-economic stability, and sustainable development, with a focus on the importance of healthy land in providing food, water resources, employment, and security [1][2]. Group 1: Global Impact of Desertification - Desertification affects nearly half of the global population, with up to 40% of land already degraded, threatening food security, water quality, and overall human health [2]. - The consequences of desertification include reduced agricultural output, worsening water supply, increased greenhouse gas emissions, and heightened risks of natural disasters and social conflicts [2]. Group 2: China's Efforts in Combating Desertification - China has made significant progress in desertification control, transitioning from "desert encroachment" to "greening efforts," and has achieved a dual reduction in desertified and sandy land areas [1][4]. - The country actively participates in global desertification governance, sharing its successful experiences and technologies, such as the "Three-North Shelter Forest Program," to assist other regions like the Sahel and Central Asia [5][6]. Group 3: Innovative Techniques and Global Cooperation - Various innovative techniques for desertification control include the use of biological soil crusts and water resource management strategies, which are essential for transforming sand into fertile soil [3]. - China promotes international cooperation through training programs, forums, and the establishment of cross-border desertification control centers, contributing to global efforts in combating desertification [5][6].
