Wetland sample sampling device based on ecological environment index evaluation

Abstract

The invention discloses a wetland sampling device based on ecological environment index evaluation, and relates to the technical field of wetland sampling devices. The sampling device comprises: an adjustable supporting table mounted on a wetland and a long sampling cylinder for sampling a soft soil layer of the wetland, and a driving device for driving the sampling long cylinder to move up and down is inserted into the adjustable supporting table. The adjustable supporting table comprises a polygonal platform plate; a supporting seat for mounting a driving device is fixed in the middle of each side surface of the platform plate; each corner of the platform plate is provided with a supporting assembly with the adjustable length; and the long sampling barrel comprises a plurality of sections of sample separation barrels which are in threaded connection, a feeding barrel which is in threaded connection with the sample separation barrel at the lowest end and a retaining plate which is inserted into the lower part of the sample separation barrel. The adjustable supporting table, the sampling long cylinder and the driving device are matched to form the systematic sampling device, vertical multi-point stable sampling is facilitated, operation is reliable and convenient, and the sampling device is suitable for sampling of a wetland soil sample layer.

Description

technical field [0001] The invention belongs to the technical field of wetland sampling devices, in particular to a wetland sample sampling device based on ecological environment index evaluation. Background technique [0002] As a special type of ecosystem in the transition between land and water, wetlands, together with forests and oceans, are known as the three major ecosystems in the world. Although the wetland area only accounts for 4% to 6% of the global area, the carbon storage in the wetland ecosystem accounts for 12% to 24% of the global terrestrial carbon storage. The high productivity level and special reducing environment in the wetland ecosystem, Make the wetland present the function of carbon sink in the process of carbon storage. With the in-depth study of the driving mechanism of global change, wetlands, as an important carbon source or carbon sink, have been paid more and more attention, and have become one of the research hotspots and key contents in wetla...

Problems solved by technology

However, the above-mentioned technologies and patents focus on the extraction process of the soil, and a large amount of manpower is used. Manual sampling is time-consuming and laborious in wetlands. Before sampling and during the sampling process, the sampling personnel will squeeze and deform the wet and soft coating, and the sampling data Changes with the actual data, manual sampling comparison points are less, further reducing the accuracy of sampling samples
