Abstract:According to the concept developed by the Society for Ecological Restoration, ecological restoration is the process of assisting in the recovery of the degraded, damaged or destroyed ecosystems with varying degrees of human intervention. Coastal zone is an extremely important carbon pool in the world. High-intensity development leads to serious degradation of coastal ecosystem and weakening of carbon sequestration capacity of ecosystem. It is urgent to protect and repair the damaged coastal ecosystem. The change of carbon storage function can indirectly reflect the stability and health of the ecosystem. Studying the spatial and temporal variation differences and laws of carbon storage in coastal zones can scientifically guide the protection and restoration of coastal ecosystems. In this paper, the carbon storage function of Dongying coastal zone in 2005,2010,2015 and 2018 was evaluated by InVEST model, and the dynamic changes of carbon storage and ‘carbon source carbon sink’ in the study area were analyzed. According to the spatial difference of carbon loss in coastal zone and the law of ecosystem succession, the restoration scheme was proposed. The results showed that during 2005-2018, a large number of coastal wetlands in the coastal zone were artificially developed, the primary ecological landscape was destroyed, and the carbon storage function continued to weaken. The total amount of carbon storage decreased by 1.34×106 t in 13 years, among which the evaluation level of carbon storage function of regional ecosystem in 868 km2 was poor and extremely poor. Spatially, the most severely damaged areas are mainly located in the northern, northeastern and southeastern parts of the coastline, with significant ecosystem destruction and degradation. According to the degree of carbon loss, Dongying coastal zone is divided into natural recovery area, artificial auxiliary area and ecological reconstruction area. By Adjusting and changing land use development methods to mitigate damage to the coastal zone ecosystem from human activities and restoring the native vegetation landscape of the area. In the natural recovery area, it is suggested to strengthen the protection of the recovery area and stabilize the carbon storage capacity. In the artificial auxiliary area, it is suggested to rectify the extensive mode of auxiliary area and shape the carbon storage corridor; In the ecological reconstruction area, it is suggested to return the coastal wetland in the reconstruction area to reverse the trend of carbon loss. By improving and restoring the carbon storage function of coastal ecosystem, the protection and restoration of the overall ecosystem in the study area can be realized.
