Background
The carbon burying rate of the global coastal wetland is (218 +/-24) g.m < -2 > a < -1 > which is more than 40 times higher than that of a land forest ecosystem, and the generation of CH4 is blocked by SO42 < -ions which are abundantly present in the coastal wetland, SO that the emission of CH4 is reduced (Mcleod et al, 2011). Coastal wetlands are one of the most dense sinks of carbon on earth due to the influence of cyclic tidal flooding by seawater, along with higher carbon accumulation rates and lower CH4 emissions. Coastal wetlands can capture and bury CO2 in the atmosphere from the ocean and the atmosphere, and the "blue carbon" of coastal wetlands plays a very important role in mitigating climate change (Kirwan and Mudd, 2012). Research has shown that the annual carbon deposit per square kilometre in coastal wetlands is expected to reach 0.22 Gg C, which is equivalent to CO2 emitted by the combustion of 3.36X 105L of gasoline (Davis et al 2015). Compared with other land ecosystems, the coastal wetland ecosystem has stronger carbon fixation capacity and ecological service value function, can slow down the emission of greenhouse gases, and can bring economic and social benefits for coastal countries and even the world. Therefore, the method for effectively evaluating the carbon sink capacity and the ecosystem service function of the coastal wetland is an important theoretical basis for formulating sink increase and emission reduction and is an important basis for realizing the carbon neutralization target in China.
The existing soil carbon flux measuring device is usually inserted into soil through a cylindrical sampling tube, and sampling is carried out through the sampling tube. But the unable shutoff of sampling tube bottom, when proposing the sampling tube, the soil of bottom can leak off, leads to the soil sample to reduce, measures inaccurately. Simultaneously, the sampling tube when inserting soil, the frictional force between the soil in the sampling tube and the sampling tube can lead to soil axial compression, and then makes the height of the soil sample that fetches a sample change, and then also can lead to measuring inaccurately.

after the auger (19) drills into soil with a specified depth, the flywheel (5) stops rotating, the rotating rod (3) is lifted up and the rotating rod (3) is rotated at the same time, the auger (19) brings out the soil, the bristles (10) brush the soil on the helical blades and fall on the receiving tray (20), and after the soil sample chamber is air-dried, the soil sample chamber is crushed and sieved, and the carbon and nitrogen storage amount and related properties of the soil are measured;
calculating the carbon reserve of the soil layer:
wherein SOC is the carbon reserve (kg/hm) of the soil layer(2))，C(N)iThe organic carbon content (g/kg) of the ith soil layer DiVolume weight of ith soil layer (g/cm)(3))，HiThickness of ith soil layer (cm), GiAnd the volume content (%) of the gravel in the ith soil layer.
