Description

Technical Field

[0001] The utility model belongs to the technical field of field experiment sample collection, and in particular relates to a coastal wetland lateral carbon flux sample collection device. Background Art

[0002] The flow process of lateral carbon flux is the key to the material exchange of the coastal wetland-nearshore waters ecosystem. Carbon flux samples such as vegetation litter are often transferred laterally through tidal action, which in turn affects the redistribution of materials and indirectly reshapes the structure and composition of wetland communities, ultimately leading to changes in ecosystem structure and function. Accurately collecting lateral carbon flux samples such as coastal wetland vegetation litter is the key to assessing the "blue carbon" potential of coastal wetlands. However, in the current lateral carbon flux sample collection process, the reciprocating process of the tide often leads to the secondary loss of large litter samples that have been collected, thereby reducing the accuracy of sample collection and even often causing the failure of sampling. On the other hand, under the huge impact of the tide, the traditional sample collection device is not installed firmly enough, which will cause it to tilt or collapse under the impact of the tide, thus seriously affecting the normal collection of the sample collection device. In general, the current large litter carbon flux sample collection method is cumbersome, the sampling operation is inconvenient, the labor cost is too high, and it is easy to cause accuracy deviation in the evaluation and analysis.
