"今年草场草长得很好，草原更美了，我们在这里干活儿能挣钱，恢复后的草场生产还能再有一部分收入，真的非常高兴"，巴彦淖尔市乌拉特中旗新忽热苏 木乌兰朝鲁嘎查牧民额尔登其其格感受到了"三北"工程给生活带来的改变。2024年， 蒙草生态 在当地开展风电光伏一体化工程沙化土地 综合 治理，选用蒙 农1号蒙古冰草等乡土草种进行科学治沙，取得良好成效。值得一提的是，应用在项目中的冰草品种，正是产自蒙草生态在当地建设的优质种源繁育基地， 防沙治沙用种真正做到了"可追溯、有保障"。 应用蒙农1号蒙古冰草等草种治理乌拉特中旗11.2万亩沙化土地 新品种成为沙地治理首选草种 冰草具有抗旱、耐寒、耐风沙等优点，生长在年降水量为200～350mm的地区，旱作也能正常生长。但普通冰草品种种子单产水平低、生态适用性有限，生 态恢复速度较慢，对土壤要求比较高，配套的栽培管理技术落后、育繁推产业体系不健全，影响生态治理效率和产业经济发展。 蒙农1号蒙古冰草，株高约为90-120厘米，叶片深绿色，抗旱、抗寒，适应性强；春季返青早，秋季枯黄晚，青绿期长，是干旱及半干旱地区修复退化沙化 草地、防止水土流失首选草种。 年产量超1625吨为"三北"攻 ...

Group 1 - The core viewpoint emphasizes the importance of scientific methods in combating desertification and improving ecological systems in Xiangwu County, Liaoning Province [1][3][5] - The county has implemented innovative projects such as "four major projects" to build a comprehensive windbreak and sand-fixation system, which includes using trees, grass, water, and light to combat sand [5] - The survival rate of the grafting project for red pine has exceeded 90%, indicating a successful approach to enhance the quality of afforestation efforts in sandy areas [3] Group 2 - The forest coverage in Xiangwu County has increased from 2.9% to over 30%, demonstrating significant progress in ecological restoration [5] - The introduction of solar panels in agricultural fields has transformed previously barren sandy land into productive areas, showcasing the dual benefits of renewable energy and agricultural improvement [5] - The county's efforts have led to the advancement of the "Three North" shelterbelt towards the core of the Keshiketeng Desert by 13 kilometers, highlighting the effectiveness of their ecological initiatives [5]

Core Viewpoint - The article highlights the successful efforts in combating desertification in Liaoning Province, particularly through the introduction and cultivation of the Chinese fir (樟子松) in the region, showcasing a significant transformation from sand encroachment to afforestation and environmental restoration [1][6][9]. Group 1: Historical Context and Development - In the 1950s, the establishment of the Liaoning Provincial Forestry Research Station marked the beginning of organized efforts to combat desertification in the region [1][6]. - The introduction of Chinese fir by Liu Bin in the 1980s was pivotal, as it demonstrated the potential for afforestation in arid and sandy areas, despite initial challenges [3][6]. - By 1978, the afforestation technology using Chinese fir received national recognition, leading to its widespread adoption in the "Three North" regions of China, with over 10 million acres now covered [3][6]. Group 2: Contributions of Individuals - The dedication of individuals like Li Dongkui, who has spent over 30 years protecting and nurturing the Chinese fir forests, exemplifies the grassroots efforts that have contributed to the success of these initiatives [3][5][6]. - Li's commitment in harsh conditions underscores the human element in environmental restoration efforts [3][6]. Group 3: Current Achievements and Future Prospects - The area of sand-affected land in Zhangwu County has significantly decreased from 96% in the 1950s to 36.56% today, with a dramatic reduction in sandstorm days from 43 to an average of 5 per year [6]. - The merger of research institutions in 2018 has enhanced the capacity for sand management and afforestation, with over 20 billion seedlings produced annually [6][8]. - The adaptability of Chinese fir and other species is being leveraged for international efforts, with seedlings being exported to Mongolia for desertification control [8][9].

6月17日是世界防治荒漠化与干旱日。 "土地荒漠化是影响人类生存和发展的全球重大生态问题""人类要更好地生存和发展，就一定要防 沙治沙""扎实推进山水林田湖草沙一体化保护和系统治理"……荒漠化防治，是习近平总书记心头牵挂 的一件大事。 ——"事关我国生态安全、事关强国建设、事关中华民族永续发展" 两年前的6月，习近平总书记在内蒙古巴彦淖尔考察并主持召开加强荒漠化综合防治和推进"三 北"等重点生态工程建设座谈会强调，加强荒漠化综合防治，深入推进"三北"等重点生态工程建设，事 关我国生态安全、事关强国建设、事关中华民族永续发展，是一项功在当代、利在千秋的崇高事业。 对非凡成就，习近平总书记予以肯定：实践证明，党中央关于防沙治沙特别是"三北"等工程建设的 决策是非常正确、极富远见的，我国走出了一条符合自然规律、符合国情地情的中国特色防沙治沙道 路。 抓生态文明建设，既要靠物质，也要靠精神。总书记"点赞"过的"三北精神"、塞罕坝精神、"右玉 精神"等，激发出无数人锲而不舍、久久为功的力量。 荒漠化防治工作何以置于如此重要地位？ 从具体国情看，总书记指出，我国荒漠化防治和防沙治沙工作形势依然严峻。 我国荒漠化土地主要分 ...
