中国科学治沙，从这座东北小城出发

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].
