Device for Collecting Aeolian Sand Trapped by Wetland and Application Method thereof
Technical Field The present invention relates to the technical field of ecosystem monitoring, in particular to a device for collecting aeolian sand trapped by wetland and an application method thereof.
Background Art Wetland is a unique ecosystem formed by the interaction of water and land on the earth, with great ecological functions and value. The functions of wetland, such as flood regulation and storage, biodiversity maintenance and carbon sink have received extensive attention, but its ecological barrier function has not been fully understood. The interaction between wetland and its surrounding ecosystem determines the main ecological functions of wetlands in specific time and space. Under the natural geographical conditions where wetland and sandy lands distribute alternately, the function that water body or wet surface of wetlands can trap sand for long term is different from wind blocking and mechanical interception, and is one special important reason why wetlands can prevent the land desertification process. Compared with the shelter forest, wetland is more suitable for sand fixation near the land surface. The function that wet surface can trap aeolian sand has become an important subject in wetlands conservation, monitoring and scientific research.
At present, collecting and monitoring related to aeolian sand transportation and deposition mostly involve land desertification research and prevention and control. Collecting and monitoring devices mostly work in a horizontal collecting manner, and there is still a lack of research on wet surface capturing. Especially, the development of collecting and monitoring devices for sand fixation and deposition on a wet surface is far from satisfactory, some collecting and monitoring devices which can be applied to sand fixation and deposition on wet surface have the defects of low accuracy and quality. Therefore, the present invention provides a device for collecting aeolian sand trapped by wetland and an application method thereof to solve the defects in the prior art.

As a further improvement, the opening is a square opening, and the upper edge of inlet of the water storage and collecting funnel, the buoyancy bearing plate and the water-resisting wall are integrally connected at the opening by welding.
As a further improvement, the connection port is an external thread connection port, and the collecting bottle is detachably connected with the connection port through threads.
As a further improvement, the anti-blocking component is an anti-blocking grid, and the anti-blocking grid is matched with the opening in size.
As a further improvement, a fixing rod is provided next to one outside of the buoyancy plate, the lower end of the fixing rod is vertically inserted into sediment of a monitoring site, and the fixing hole is connected to the fixing rod with the fixing rope.
