Core Viewpoint - The article highlights the efforts and progress in combating desertification in the Qinghai province, particularly in the Sanjiangyuan region, which is crucial for ecological security and sustainable development in China [1][2]. Group 1: Desertification and Ecological Impact - Desertification significantly affects global ecological security, poverty alleviation, social stability, and sustainable development [1]. - In the 1990s, the area of desertified land in Guinan County reached 3.42 million mu, with desert areas accounting for 1.42 million mu, or 14.2% of the total area [1]. - The desert expanded at a rate of 5 to 15 meters per year, leading to severe environmental challenges [1]. Group 2: Restoration Efforts and Achievements - Guinan County has improved its forest coverage from 2.6% before 1996 to 19.24% currently, with 1.95 million mu of desertified land effectively treated [2]. - The "Three-North" project has faced challenges due to the complex nature of desertification in Qinghai, where 1.85 million mu of land is desertified, accounting for 17.2% of the total land area [2]. - The local government has implemented a funding strategy to alleviate financial pressure on grassroots levels, with 170 million yuan allocated for 2024 and 240 million yuan for 2025 [2]. Group 3: Innovative Approaches and Technology - The Sand Zhu Yu Township has reduced its desertified land from 90% to 12.3% through a combination of engineering, biological, and technological methods [3]. - The establishment of the world's largest centralized photovoltaic power generation park in the region has created an ecological model that reduces wind speed by 50% and soil moisture evaporation by 30% [3]. - The integration of photovoltaic technology with ecological restoration has transformed previously barren land into productive areas for livestock farming [3]. Group 4: Vision for Future Development - The Qinghai Provincial Forestry and Grassland Bureau emphasizes the ongoing commitment to ecological restoration and sustainable development, aiming to extend the "green wall" across the plateau [4].
