摘　　要：滨海湿地在碳循环过程中发挥着重要的作用,科学掌握滨海湿地温室气体收支状况对于应对气候变化具有重要的意义。文章研究了滨海湿地温室气体收支核算方法,按照滨海湿地覆被类型和碳库类型明确了立体空间核算单元;针对二氧化碳、甲烷和氧化亚氮的吸收和排放情况设计出核算指标体系;基于单位面积生物量法、储量差分法和收支法构建出核算方法体系;设计出滨海湿地温室气体收支核算清单,并进一步指出滨海湿地温室气体核算应用需要进一步深入研究的方向。Coastal wetlands play an important role in the process of carbon cycle,and it is of great significance to scientifically grasp the greenhouse gas absorption and emission in coastal wetlands for addressing climate change.This paper studies the accounting method of greenhouse gas absorption and emission in coastal wetland,and designs an accounting index system for the absorption and emission of carbon dioxide,methane and nitrous oxide.Then,the paper is based on biomass-per-unit-area method,reserve difference method and revenue and expenditure method to construct the accounting method system.Finally,the paper designs the accounting tables of greenhouse gas absorption and emission in coastal wetlands,and also points out the direction of further research on the application of greenhouse gas accounting in coastal wetlands.
