Research on ecological restoration and comprehensive utilization technology of abandoned quarry in the Lijiang River Basin under the background of'double carbon'
The improvement of ecosystem carbon sink function is an important direction of ecological restora-tion of abandoned quarries under the background of'double carbon'.This paper discussed the ecological res-toration project of the project and its carbon sink and sink increase management measures,taking the ecologi-cal 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 se-lection,maintenance and management can improve the soil carbon sink of abandoned quarry,promote the ef-ficient 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.
