[0002] Global climate change has led to global warming, which in turn has caused environmental problems such as rising atmospheric and ocean temperatures, rising sea levels, and melting glaciers, directly or indirectly affecting human production and life. One of the main reasons for global warming is the large amount of greenhouse gas emissions. Wetlands, known as the "kidneys of the earth", are precious natural resources and ecological systems with multiple unique functions on the earth. They not only provide humans with a large amount of food, raw materials, and water resources, but also play an important role in maintaining ecological balance, preserving biodiversity and rare species resources, conserving water sources, storing floodwaters and preventing droughts, degrading pollution, regulating the climate, replenishing groundwater, and controlling soil erosion.

[0003] When studying wetland science, it is essential to sample greenhouse gases in wetland soil. However, current wetland soil gas sampling devices can usually only sample and study greenhouse gases, with single functions and poor applicability, and cannot simultaneously monitor other wetland physical and chemical indicators such as water quality.
