四水映绿 豫见两山丨矿山变形记

Core Viewpoint - The article highlights the ecological restoration efforts at the Jiaoji Aluminum Mine in Sanmenxia, which has transformed from a heavily exploited mining area into a green landscape, showcasing a successful model of environmental rehabilitation and sustainable development [2][10]. Group 1: Ecological Restoration Efforts - The Jiaoji Aluminum Mine has completed significant restoration work, including filling 3.33 million cubic meters of earth, covering 456,100 square meters, and constructing 12,000 meters of drainage ditches, with a total treatment area of 1,116 acres [2]. - The mine has successfully restored 363 acres of dry land and 496 acres of tree-covered land, and has planted over 360 acres of crops, expected to yield 300,000 kilograms of grain annually [2][10]. - The restoration process involved a tailored ecological repair plan, which included transforming steep slopes into terraced steps and implementing effective drainage systems to manage rainwater [6][9]. Group 2: Challenges and Innovations - The restoration faced challenges such as the high steepness of slopes (up to 70 degrees) and low survival rates of initially planted tree species like white poplar, leading to a shift in strategy to include more resilient species like purple spire and alfalfa [8][9]. - The restoration team utilized a combination of manual labor and machinery, with 52 excavators and over 60 transport vehicles working simultaneously to achieve the restoration goals [7]. - The ecological restoration has turned the previously barren landscape into a thriving environment, with the first batch of white poplar trees reaching nearly two meters in height after two years [9][10]. Group 3: Community Impact and Future Prospects - The successful restoration has instilled confidence in the local community, with plans for villagers to return and develop tourism in the area, enhancing local economic opportunities [11]. - The article emphasizes the importance of ongoing environmental monitoring and joint enforcement efforts to ensure the sustainability of the restoration outcomes [12].
