在全球双碳目标与我国西部煤炭资源持续开发的形势下,干旱半干旱矿区生态系统的修复与稳定面临重大挑战.矿区生态系统修复具有多学科交叉的特点,为了解采矿活动对土壤、水资源与植被生长的影响以及相互之间响应关系的研究态势,利用CiteSpace、VOSviewer、Pajek等对Web of Science核心合集数据库检索到的1991-2022年期间发表的相关文献进行计量分析.结果表明:2010年前发文较少,其后年发文量呈抛物线式增长,尤其是近五年以来,有关矿区植被修复与土壤、水之间响应关系的相关文献数量增长迅速,受关注程度越来越高;中国发文量远高于其他国家,发文机构之间具有较紧密的学术合作网络;矿区土地复垦与生态修复一直是众多学者研究的热点,当前的研究文献集中于矿区生态遥感监测、恢复区土壤重建、矿区地下水储量与生态环境演化特征等方面.研究指出,土壤含水量是矿区影响植被生长最重要的土壤理化性质因子,埋深阈值决定地下水是否对地表植被与土壤提供水源,矿区生态系统健康受水土资源的协调影响.保水采煤技术提升、地裂缝治理、土壤健康以及基于自然的解决方案将是碳减排背景下矿山生态修复模式的主要研究方向.
Under the situation of the global dual carbon target and the sustainable exploitation of coal resources in western China,the restoration and stability of ecosystems in arid and semi-arid mining areas are facing great challenges.The ecosystem restoration in mining areas is characterized by multidisciplinary intersection.In order to understand the situation in the research field that how mining activities influencing soil,water resources and vegetation growth,and the response relationship between them,CiteSpace,VOSviewer and Pajek were used to quantitatively analyze the relevant papers published in the core collection database of Web of Science from 1991 to 2022.The results show that there were few papers published before 2010,and the number of papers published in the following years increased parabolically.Especially in the past five years,the number of related papers on the relationship between vegetation restoration and soil and water in mining areas increased rapidly,and the degree of attention has been increasing.The number of papers published in China is much higher than that in other countries,and there is a close academic cooperation network among publishing institutions.Land reclamation and ecological restoration in mining areas have always been the focuses of many scholars.The current research focuses on ecological remote sensing monitoring in mining areas,soil reconstruction in restoration areas,groundwater reserves and ecological environment evolution characteristics in mining areas.It is pointed out that soil water content is the most important soil physicochemical property factor affecting vegetation growth in mining area.The buried depth threshold determines whether groundwater provides water source for surface vegetation and soil,and the ecosystem health of mining area is affected by the coordination of water and soil resources.The improvement of water-preserved coal mining technology,ground fissure control,soil health and nature-based solutions will be the main research directions for mine ecological restoration mode under the background of carbon emission reduction.
