摘　　要：滨海湿地现状及碳储量数据是湿地生态系统功能评估和保护修复的基础。基于2021年Landsat8 OLI卫星遥感数据,以ArcGIS软件为平台,本文对广西滨海湿地进行了遥感信息提取和统计分析;进而利用InVEST模型及前人数据,定量分析了其中的红树林湿地碳储量。结果表明,广西滨海湿地现状总面积为2986.95 km^(2),其中:(1)人工湿地618.22 km^(2),占湿地总面积的20.70%,包括养殖场为469.98 km^(2)、水库128.70 km^(2)、盐田6.46 km^(2)和其他类型人工湿地13.08 km^(2);(2)自然湿地为2368.73 km^(2),占湿地总面积的79.30%,包括近海与海岸湿地2222.32 km^(2)、河流湿地137.97 km^(2)、湖泊湿地5.80 km^(2)和沼泽湿地2.64 km^(2);(3)天然与人工红树林湿地面积90.80 km^(2),红树林湿地碳储量为6.47×10^(5)t。The current situation of coastal wetlands and carbon storage are the basis of wetland ecosystem protection and restoration and ecosystem function evaluation.Based on the Landsat8 OLI satellite remote sensing data in 2021,this paper extracts and statistically analyzes the remote sensing information of coastal wetlands in Guangxi on the platform of ArcGIS software.Further,based on the InVEST model and previous data,the carbon storage of Mangrove Wetland in Guangxi is analyzed.The results show that the current total area of coastal wetlands in Guangxi is 2 986.95 km^(2),among which 618.22 km^(2) is the constructed wetland and accounting for20.70% of the total.Such artificial wetland includes 469.98 km^(2) of farms,128.70 km^(2) of reservoirs,6.46 km^(2) of salt fields while the other types of 13.08 km^(2).The natural wetland is 2 368.73 km^(2),accounting for 79.30% of the total wetland area,including 2 222.32 km^(2) of offshore and coastal wetlands,137.97 km^(2) of river wetlands,5.80km^(2) of lake wetlands and 2.64 km^(2) of swamp wetlands.The mangrove wetland area is 90.80 km^(2) and the carbon storage of mangrove wetland is 6.47×10^(5)t.
