Group 1 - The core viewpoint of the articles is the completion of a significant ecological project in the Tengger Desert, which involves a 153-kilometer "green chain" to combat desert expansion and protect the Yellow River [1][2] - The project is part of a broader initiative to manage desertification in China, emphasizing the importance of not eliminating deserts but rather managing their expansion [2][3] - The Ningxia region has successfully retreated the Tengger Desert by 25 kilometers over the past decades through various ecological projects, including the "Three-North" program [2][3] Group 2 - The locking technique involves using grass grids to stabilize shifting sands, which has proven effective in preventing desert encroachment [3][4] - Innovative technologies are being employed, such as a specialized planting tool that increases the survival rate of saplings in sandy conditions from 60% to over 80% [4] - Future plans include enhancing cooperation with Inner Mongolia for joint ecological management and developing sustainable industries like desert tourism and solar energy [5][6]

Core Insights - The "Taklamakan Desert Locking Project" aims to combat desertification through innovative engineering and ecological methods, culminating in a 3046 km "green collar" around the desert by November 28, 2024 [2][3] - The project integrates engineering, biological, and photovoltaic techniques to create a comprehensive sand prevention and control technology model [3] - Experts emphasize the importance of interdisciplinary collaboration and technological innovation to ensure the sustainability and stability of the locking project [2][3] Group 1 - The Taklamakan Desert is the largest shifting sand desert in China, posing significant threats to surrounding oases and infrastructure due to frequent sandstorms [2] - A high-level academic salon was held in Hotan, Xinjiang, where nearly a hundred experts discussed scientific governance, technological breakthroughs, and innovative models for high-quality sand prevention and control [2] - Key topics included "Smart Diagnosis of Wind and Sand and Intelligent Decision-Making for Sand Control," "Utilization of Saline Water in Desert Areas," and "Ecological Photovoltaics for High-Quality Sand Control" [2] Group 2 - The project requires the development and application of new materials, technologies, and models to further consolidate the locking results [3] - The prevention and control of desertification is characterized by a comprehensive, long-term, and holistic approach, necessitating new ideas and pathways for integrating sand control with industries like photovoltaics and tourism [3] - During the event, two roundtable forums were held on "Desert Edge Effects and Locking Projects" and "New Materials and Technologies for Sand Prevention and Control," along with field visits to research stations and construction sites [3]

风吹过腾格里沙漠。它卷起细密的黄沙，雕刻出连绵不绝的沙丘，将一切足迹轻易抹去。然而今天，在 这片古老沙海的边缘，一场静默而坚韧的绿色行动正在展开。 从2014年到2023年，中国绿化基金会携手联合国环境规划署、气候组织等伙伴，共同发起一个名为"百 万森林计划-沙漠锁边林行动"的项目。 锁边林项目将目光投向了腾格里沙漠的边缘地带——内蒙古阿拉善和甘肃民勤。在这里，他们选择了一 种巧妙的策略：在沙漠的边界线上，种下一道由多种耐旱灌木组成的"绿色长城"，为流动的沙海锁上一 道道绿色边界，防止沙漠继续向外侵蚀，也从源头减少沙尘暴。 项目实施九年后，中国林业科学研究院生态保护与修复研究所、中国林业科学研究院沙漠林业实验中心 和甘肃省民勤治沙综合试验站组建科研团队，对这个项目的结果进行了全面而科学的评估。 研究结果显示，截至2023年底，锁边林项目取得了令人瞩目的成果：超过1000万株树木被种植，植树面 积达到约16.3万亩，相当于15219个标准足球场。而修复的荒漠化土地面积，更是高达1.1亿平方米。 这九年里，平均每分钟，就有2棵新的树苗扎根。平均每秒钟，就有大约3.9平方米的沙化土地被从流沙 手中夺回。这片面积，大 ...
