Description

Technical Field

[0001] The present invention relates to the technical field of carbon sink process determination, and in particular to a karst carbon sink process determination device. Background Art

[0002] Rainwater absorbs carbon dioxide from the air during its fall, and then passes through the soil, further absorbing more carbon dioxide to form weakly acidic water rich in carbonic acid. These weakly acidic waters flow along the cracks of limestone and react chemically with the limestone to produce karst water rich in bicarbonate (HCO3-) and calcium and magnesium ions. This continuous chemical reaction process is the carbon sink process of karst action.

[0003] Carbon in the karst area is constantly circulating in the lithosphere, hydrosphere, atmosphere and biosphere. 2 When entering the karst area, it enters the karst area carbon cycle through precipitation dissolution, photosynthesis absorption and soil absorption. Therefore, the premise of studying the carbon sink in the karst area is to reveal the mutual transformation process of carbon in different media. Due to the unique binary and three-dimensional structure of the karst area, it is more difficult to reveal the carbon cycle laws in the karst ecosystem.

[0038] Method of use: When using, first open the box cover 22, then plant plants at the position of the soil particle layer 18 of the soil layer component 14, then add a proper amount of water to the water storage chamber 12 through the return pipe 21 at the bottom of the water guide trough 2, and add a proper amount of water to the water storage tank 19, then fix the placement component 3 on the fixing buckles 29 at different positions at the rear end of the inner wall of the box body 1, place the positioning block 31 in the fixing buckle 29 and then place the rock sample on the placement plate 33 of the support rod 32, and also put the rock sample at different positions on the upper end of the soil layer component 14, then close the box cover 22, operate the control panel 48, let the water pump 35 in the support frame 34 work, the water pump 35 draws water from the water storage chamber 12 through the water inlet pipe 36, and then transports the water to the first water guide pipe 24 and the water spray component 23 through the water outlet pipe 37. The water flows into the second water pipe 25 and is sprayed out from the water outlet 26 to simulate the rainfall process, and part of the fallen water can gradually penetrate through the soil layer component 14 and flow back into the water storage chamber 12 through the seepage holes 13 on the partition 11. The water passing through the soil layer component 14 will gradually pass through the soil particle layer 18 from top to bottom to soak it and be used as a source of water for plant growth, and then pass through the organic matter layer 17. The organic matter can cement the soil particles and cooperate with the aggregate layer 16 to improve the air permeability and water permeability of the soil. In addition, the organic matter can also increase the number and size of soil pores, improve the soil's water and fertilizer retention capacity, and is beneficial to the penetration and storage of water in the soil, which is convenient for the normal growth of plants and can also realize the circulation of carbon elements. Finally, the excess water will flow into the water storage chamber 12 after being filtered by the gravel layer 15.

[0039] When spraying water, the control valve 28 on the corresponding water pipe 27 can be switched to select whether the water spray component 23 is working, and the size of the water flow of the working water spray component 23 can be controlled, so as to realize the control of different positions and different precipitation sizes in the box body 1. At the same time, the water storage tank 19 can store the fallen water for a short time, and the excess water can flow along the water guide groove 2, and finally flow back into the water storage chamber 12 through the return pipe 21. At the same time, the air volume generated by the fan 38 is removed by the filter 39 to remove dust and particulate impurities in the air, and then the air volume is transported to the dryer 41 through the first air guide 4 to remove moisture in the air, and then the wind is transported to the wind on the slot 42 through the second air guide 45. The air is blown into the box body 1 by the air nozzle 43. When the air is blown into the box body 1, since the upper and lower ends of the air nozzle 43 are provided with spoilers 44 with different directions, the direction of the wind can be changed to a certain extent, which can not only make the wind fill the box body 1 faster, but also make it contact and merge with the water body faster. By simulating the external environment in the box body 1, and then using the carbon dioxide concentration sensor 46 and the temperature and humidity sensor 47 to monitor the changes in temperature, humidity, gas concentration, etc. in the box body 1, the release and absorption mechanism of carbon in the rock dissolution process can be analyzed. After a period of time, the rock sample is taken out, and then the mass fraction of the rock sample before and after being put in is compared, and the changes in various parameters can know the key indicators related to the carbon sink process.
