Description

TECHNICAL FIELD

[0001] The utility model relates to soil carbon sink sampling technical field, specifically a soil carbon sink sampling device. BACKGROUND

[0002] Carbon sink generally refers to the process, activity, mechanism of removing carbon dioxide from the air, which mainly includes the amount or ability of forest, grassland and other ecological systems to absorb and store carbon dioxide. Forests form carbon sinks through plant photosynthesis and soil carbon sequestration, while grasslands achieve significant carbon sequestration function through rapid growth of perennial herbaceous plants, large underground root network and soil organic carbon accumulation. Grassland carbon sink is particularly concentrated in the soil layer, with underground biomass carbon storage accounting for more than 60% of total carbon storage.

[0003] Carbon sink monitoring refers to measuring, recording and analyzing the processes of forest, grassland and land use change to determine the amount of carbon dioxide absorbed and emitted by these ecosystems. Monitoring of grassland ecosystems requires special attention to indicators such as seasonal dynamics of aboveground biomass, distribution characteristics of underground root system and vertical profile of soil organic carbon. Carbon sink monitoring can accurately measure the increase in carbon storage, which is a major initiative to reduce monitoring costs, improve monitoring accuracy and provide necessary parameters, and is particularly important for grassland ecosystems that are easily affected by climate change and human activities.

[0004] Therefore, it is necessary to sample and analyze specific regions or ecosystems to monitor their carbon sink capacity. The existing soil sampling device is generally provided with rollers at the bottom of the device to ensure that the device can be easily carried and moved, which makes the sampling device prone to shaking during drilling and sampling, affecting the sampling progress, and in severe cases, the sampling device may tip over, resulting in failure of soil sampling.
