摘　　要：生态系统碳汇功能提升是“双碳”背景下废弃采石场生态修复的重要方向。以兴安县川江、斧子口水利枢纽工程采石场生态修复工程为例,探讨该工程的生态修复工程及其碳汇和增汇管理措施。结果表明:采用边坡生态修复、土壤配制、植物选配、养护管理等多方面措施可以提高废弃采石场土壤碳汇量并促进林草植被的高效生长,减少区域水土流失;加强土壤修复可以减少碳汇损失。减少生态修复过程可计量碳汇量提升、生态修复及后期管理中碳损失,可以实现废弃采石场生态修复的碳汇提升最大化。The improvement of ecosystem carbon sink function is an important direction of ecological restoration of abandoned quarries under the background of'double carbon'.This paper discussed the ecological restoration project of the project and its carbon sink and sink increase management measures,taking the ecological restoration project of the quarry of Chuanjiang and Fuzikou Water Conservancy Project in Xing'an County as an example.The results show that the measures of slope ecological restoration,soil preparation,plant selection,maintenance and management can improve the soil carbon sink of abandoned quarry,promote the efficient growth of forest and grass vegetation,and reduce regional soil erosion.Enhancing soil remediation can reduce carbon sink losses.Reducing the measurable carbon sink increase in the ecological restoration process,carbon loss in ecological restoration and later management can maximize the carbon sink increase in the ecological restoration of abandoned quarries.
