摘　　要：海岸带蓝碳因其较高固碳能力是海洋碳汇的重要组成部分,对于调节全球碳中和发挥着无可替代的作用。文章结合遥感识别和现场验证所占面积,对宁波市的海岸带蓝碳碳汇能力本底现状进行估算,得出宁波市海岸年固碳量约为146608 TC(以CO_(2)计),其中主要贡献者为互花米草,其次为海三棱藨草,最后是光滩和碱蓬。此外,结合打造生态海塘的理念,估算出宁波市人工岸线生态化工程年增汇能力5060 TC,生态修复年增汇能力14666 TC,湿地植物秸秆年增汇能力4.5 TC。因地制宜地提出了提高增汇能力、建立海洋生态指标体系和建设蓝碳交易示范区等相关建议。Coastal blue carbon is an important part of the ocean carbon pool because of its high carbon sequestration capacity.It plays an irreplaceable role in regulating global carbon neutrality.Combined with the area occupied by remote sensing identification and field verification,this paper estimates the background status of blue carbon sequestration capacity of coastal zone in Ningbo.It is concluded that the annual carbon sequestration capacity of coastal zone in Ningbo is about 146,608 TC(calculated by CO_(2)),of which the main contributor is spartina alterniflora,followed by scirpus mariqueter,and finally guangtan and Suaeda salsa.By combining with the concept of building an ecological seawall,the annual foreign exchange increase capacity of Ningbo artificial coastline ecological chemical project is estimated to be 5060 TC.The annual foreign exchange increase capacity of ecological restoration is 14,666 TC,and the annual foreign exchange increase capacity of wetland plant straw is estimated to be 4.5 TC.According to local conditions,this study suggests to improve the capacity of increasing foreign exchange,establish marine ecological index system,and build blue carbon trading demonstration area.
