此外，泾源县还建立长效管控机制，压实县、乡、村三级管理责任，成立专业管护队伍，对修复区 域进行常态化巡查、维护。以三关口矿山公园为基础，导入生态旅游、生态康养等产业，反哺生态修复 成效的持久维护。 如今，三关口废弃矿区绿化率显著提升，区域空气质量大幅改善。颉河三关口段出境水质稳定在Ⅱ 类水质以上，重现"水清河畅"的美景。周边村民的收入来源从依赖矿企务工转变为多元化的绿色产业收 入。矿区周边的蒿店、集村等村的肉牛养殖、中药材种植、菌菇产业等也发展得红红火火，实现了生态 颜值与产业价值的双重提升。 日前，宁夏回族自治区固原市泾源县三关口废弃矿区生态修复案例成功入选全国第二批矿区生态修 复典型案例，这是宁夏践行"绿水青山就是金山银山"理念的又一生动范例。 三关口位于泾源县六盘山镇，紧邻六盘山自治区级自然保护区，曾是宁夏境内及周边地区建筑石料 的主产区和核心供应地。2017年，宁夏开启"绿盾2017"专项行动，实施矿山生态修复，先后投入1.2亿 元，关停33口石灰窑和6家石料厂、2家水泥厂，拆除构筑物、建筑物22395平方米，治理面积138.51公 顷。在生态修复过程中，系统融合了"关停清退、地貌重塑、科学复绿、水系 ...

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].

Core Viewpoint - The article discusses the ecological restoration project in Tieshan Port District, Beihai City, Guangxi, focusing on transforming abandoned mining sites into productive agricultural land and shrimp farming areas. Group 1: Project Overview - The ecological restoration project is commissioned by the local natural resources department and involves the restoration of 31 historical abandoned mining sites, with 22 sites requiring remediation over an area of 54 square kilometers, aiming for a total restoration area of 58 square kilometers [2]. Group 2: Restoration Techniques - The project employs various engineering measures such as slope reduction, slope surface restoration, foot support, drainage ditches, vegetation re-greening, and monitoring to eliminate geological disaster risks in the exposed and damaged areas [2]. - For areas intended to be restored as arable land, techniques include drainage ditches, land leveling, soil enrichment, and planting crops like corn and cassava, utilizing nearby seawater to support the development of specialty agriculture [2]. Group 3: Results and Impact - Over 120 acres of the restored area have been converted into seawater shrimp farming ponds, while some reclaimed farmland has been planted with crops, transforming the former "ecological scars" into "wealthy ponds and fields" [2][3].

Core Viewpoint - The article highlights the sustainable development approach taken by Pucheng County in Shaanxi Province, focusing on ecological restoration of mining areas while integrating rural revitalization and green development. Group 1: Ecological Restoration Efforts - Pucheng County has implemented a comprehensive ecological restoration strategy, repairing 240 sites, increasing arable land by 76.78 hectares, and adding 214.2 hectares of forest and 246.6 hectares of grassland [1] - A thorough investigation identified over 260 mining sites needing restoration, leading to the establishment of detailed ecological environment archives [2] - Specific measures for different mining conditions include slope reduction, wall construction, and water drainage systems to mitigate geological hazards [3] Group 2: Financial and Regulatory Framework - The county has allocated approximately 196.86 million yuan for ecological restoration projects, integrating various agricultural and environmental funds [2] - Pucheng County emphasizes the responsibility of mining companies to contribute to ecological restoration funds, ensuring adequate financial resources for projects [2] Group 3: Integration with Economic Development - The ecological restoration efforts have been linked with local economic activities, promoting the cultivation of medicinal herbs and economic crops, thus transforming the local economy [4] - The improved ecological environment has attracted community engagement in recreational activities, enhancing the quality of life for residents [4] Group 4: Governance and Community Involvement - A comprehensive regulatory mechanism has been established to oversee the entire process of ecological restoration, ensuring compliance with design and construction standards [5] - The county has fostered a collaborative governance model that combines community participation, legal frameworks, and ecological restoration efforts [6]
