Core Viewpoint - The article highlights the ecological restoration efforts undertaken by the Hebei Geological Bureau's Second Geological Team, showcasing their successful transformation from mineral exploration to ecological civilization construction, with significant achievements in both land and marine environments [3][4][6]. Group 1: Mountain Restoration - The Second Geological Team has successfully restored over 500 mining sites since 2015, covering an area of more than 100,000 acres, and has added 6,603 acres of arable land, resulting in an annual reduction of carbon emissions by 24,300 tons and direct economic benefits exceeding 1.6 billion yuan [6]. - Innovative techniques such as "spray concrete floating platforms" and "hanging soil troughs" have been developed to address steep slopes and land degradation issues in mining areas [4][5]. - The team has implemented an "EPC" governance model for mining restoration, integrating government leadership, policy support, and social participation, which has been promoted across the province [5][6]. Group 2: Land Improvement - The team has completed 184 land improvement project designs since 2010, covering an area of 200,000 acres and adding over 20,000 acres of arable land [9]. - They have developed new technologies for soil quality improvement, water conservation, and crop yield enhancement, addressing previous limitations in land restoration techniques [8][9]. - The team has also engaged in urban development projects, conducting over 100 industrial site investigations and creating a comprehensive geological survey methodology for various types of contaminated sites [9]. Group 3: Marine Restoration - The Second Geological Team is responsible for the ecological restoration of the largest contiguous seagrass bed in China, which has faced degradation due to climate change and unsustainable fishing practices [10][11]. - The restoration project employs a combination of natural recovery and artificial intervention methods, including substrate restoration, transplantation, and seeding [11][12]. - The project has successfully protected and restored 638.47 hectares of seagrass bed, increasing biodiversity with the number of benthic species rising from 60 to 111, and the biodiversity index improving by 42.3% [13][14].
