生态新方位丨高原又见青青草

Core Viewpoint - The ecological restoration project in the Muli mining area of Qinghai Province, initiated by the Guangxi Coal Geological Bureau, has successfully transformed a previously degraded landscape into a thriving ecosystem, showcasing innovative techniques and significant environmental benefits [3][9][10]. Group 1: Project Background and Challenges - The Muli mining area, located at an average altitude of 4200 meters, suffered severe ecological damage due to years of open-pit mining, leaving behind numerous pits and waste piles [3]. - In 2020, a national ecological restoration initiative was launched following directives from President Xi Jinping, marking the beginning of a significant ecological restoration effort [3][4]. - The project faced multiple challenges, including high altitude, low oxygen levels, and limited construction time, necessitating innovative solutions [5][6]. Group 2: Innovative Techniques and Implementation - The Guangxi Coal Geological Bureau developed a "seven-step" grass planting method, which included soil improvement and the use of organic fertilizers, totaling over 200 tons [7]. - A real-time monitoring system was established using satellite remote sensing and drone surveying to track vegetation growth and ensure the effectiveness of restoration efforts [7]. - The project team conducted over 50 soil composition experiments to select suitable native grass species, achieving a 30% higher survival rate compared to traditional methods [7]. Group 3: Results and Achievements - The restoration project successfully covered an area of 224,667.8 square meters, equivalent to 314 standard football fields, with a grass seed germination rate of 85% and vegetation coverage increasing from less than 5% to over 65% [9]. - The project was completed at 10% below the estimated cost, saving over 5 million yuan, and established a low-cost, high-efficiency restoration model [10]. - The ecological system's service value increased by over 200 million yuan, with water conservation capacity improving by 40% and soil erosion decreasing by 60% [10]. Group 4: Broader Impact and Future Directions - The success of the Muli project reflects a broader transformation of the Guangxi Coal Geological Bureau from a mining-focused entity to an ecological restoration leader, contributing to various projects across China [12][13]. - The team has developed a comprehensive service capability encompassing exploration, design, construction, and monitoring, with plans to apply their methods to other ecological restoration projects, including the Yellow River key ecological area [13][14]. - The Guangxi Coal Geological Bureau aims to continue leveraging technological innovation in various fields, ensuring national energy resource security while promoting harmonious coexistence between humans and nature [14].
