摘　　要：为探讨我国不同湿地生态系统类型固碳价值的分异特点及其在总湿地生态系统服务价值中的占比规律,探讨湿地生态系统固碳价值的影响因素,以我国典型内陆和滨海湿地为研究对象,基于2011年Landsat TM 5遥感影像分析和前期研究,系统梳理了其固碳价值和分异规律。研究结果表明,内陆湿地生态系统单位面积的年固碳价值为1400~43360元/hm^(2),最高值在太湖湿地,其次是若尔盖湿地(19990元/hm^(2)),最低值在白洋淀湿地;固碳价值在总服务价值的占比最高的是四川若尔盖湿地(10.08%),占比不足1%的有贵州草海湿地、湖南洞庭湖湿地、河北白洋淀湿地、新疆博斯腾湖湿地、青海青海湖。滨海湿地生态系统单位面积的年固碳价值为3711.50~6448.00元/hm^(2),平均4880.57元/hm^(2),固碳价值在总生态系统服务价值的占比(最低为10.72%,平均值为13.19%)明显高于内陆湿地。研究结果可为湿地生态系统保护、修复和管理提供支撑。Wetlands have the highest ecosystem service value on earth per unit area.Carbon sequestra-tion is among the most valuable of ecosystem services,and closely related to nutrient cycling and climate change.In this study,typical inland and coastal wetlands in China were studied,and we determined car-bon sequestration values among the different wetland types,their proportional contributions to wetland ecosystem services,and then we also explored the factors affecting carbon sequestration in wetland eco-systems,systematically analyzed carbon sequestration values and the differentiation rules of different wet-land ecosystems.Our analysis was based on Landsat TM 5 remote sensing images from 2011 and research on wetland carbon sequestration values conducted by our team and other relevant research.The spatial dif-ferentiation of carbon sequestration values in wetland ecosystems was significant and the variation in the values among inland wetlands was higher than that among coastal wetlands.The annual carbon sequestra-tion value of inland wetlands per unit area was in the range of 1400-43360 yuan/hm^(2),with the highest value in Taihu Lake wetland(43360 yuan/hm^(2)),followed by the Zoige wetland(19990 yuan/hm^(2)),and the lowest value was in Baiyangdian wetland(1400 yuan/hm^(2)).The proportion of carbon sequestration value to total service value was highest in the Zoige wetland(Sichuan)at 10.08%,while the proportions in Caohai wetland(Guizhou),Dongting Lake wetland(Hunan),the Baiyangdian wetland(Hebei),Bosten Lake wetland(Xinjiang),and Qinghai Lake wetland(Qinghai)were less than 1%.The annual carbon se-questration values of coastal wetland ecosystems per unit area were in the range of 3711.50-6448.00 yu-an/hm^(2),with an average value of 4880.57 yuan/hm^(2).The proportions of carbon sequestration value to to-tal ecosystem service value for the coastal wetlands(minimum 10.72%,average 13.19%)was significant-ly higher than those of inland wetlands.To enhance the carbon sequestration function and value of wet-land ecosystems,we
