【摘要】 遵循“基于自然的解决方案（NbS）”的生态理念，探讨煤矿废弃地粉煤灰堆场湿地生态修复路径。以徐州九里湖湿地的北湖区域为研究对象，深入分析煤矿废弃地粉煤灰堆场特征和问题，统筹污染控制、多样化生境恢复和生态景观营造需求，提出“粉煤灰堆场五位一体生态重建策略”，通过地形重塑、水系梳理、土壤改良复垦、栖息地营造、植被恢复及健康水生态系统构建等措施，推动研究区域实现“粉煤灰堆积场—低洼地—拟自然人工湿地—自然湿地”的逐渐转化，以期为煤矿废弃地粉煤灰堆场健康湿地生态系统重建提供低成本、可复制的实践借鉴。更多还原

【Abstract】 Following the ecological concept of "Nature-based Solutions(NbS)", the approach to ecological restoration of abandoned coal mine was discussed. A case study was conducted of Beihu area of Jiulihu wetland in Xuzhou, this paper presents a deep insight into the characteristics and problems of fly ash dumps in abandoned coal mine, coordinates the needs of pollution control, diversified habitat restoration and ecological landscape construction, and proposes a "five-inone ecological reconstruction strategy for fly ash dumps", and promotes the gradual transformation of "fly ash accumulation sites-low-lying lands-quasi-natural artificial wetlands-natural wetlands" in the study area through measures such as terrain remodeling, water system combing, soil improvement and reclamation, habitat construction, vegetation restoration and healthy water ecosystem construction. In order to provide a low-cost and repeatable practical reference for the reconstruction of healthy wetland ecosystem in the abandoned coal mine.更多还原
