Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a soil sampler for monitoring the ecological environment of coastal wetlands and tidal flats. Background Art

[0002] Coastal wetland mudflats are important ecosystems that play an important role in biodiversity conservation, climate regulation, hydrological control, and coastal protection. However, due to global climate change, sea level rise, increased extreme weather events, and the impact of human activities (such as land reclamation, pollution emissions, and infrastructure construction), coastal wetland mudflats face serious degradation problems, including reduced wetland area, increased salinization, vegetation decline, and decreased ecological functions. These changes not only threaten the stability of wetland ecosystems but also affect the environmental sustainability of coastal areas. In order to facilitate the monitoring of wetland mudflat environments, it is often necessary to sample the wetland mudflat soil, which requires the use of soil samplers. Although the currently used wetland mudflat soil samplers can meet normal usage needs, they still have defects in actual use. For example, the currently used wetland mudflat soil samplers are relatively inconvenient to disassemble. When the sampler is blocked, it is not convenient to remove the sampler for cleaning, which is inconvenient for soil cleaning and needs to be improved. Therefore, a soil sampler for monitoring the ecological environment of coastal wetland mudflats is proposed. Summary of the Invention
