Intertidal zone benthonic animal layered sampler

Abstract

The invention relates to an intertidal zone benthonic animal layered sampler. The intertidal zone benthonic animal layered sampler comprises a handle part and a box part of which the upper part and the lower part are opened. The handle part is T-shaped, and is connected with the box part through a locking button. Three faces of the box part are fixing vertical plates, and one face is a moveable vertical plate which can be upwards pulled out and in which a separating hole is reserved. A separating plate is inserted into the box from the separating hole. The intertidal zone benthonic animal layered sampler uses a split-type structure, and is convenient for transportation, storage and use. The T-shaped handle is used for sampling by using a hand to downwards press or sampling by using a rubber hammer to knock, the operation is simple and convenient, labor-saving, and suitable for multiple types of mud flat, such as muddy, sandy and mixed muddy and sandy. A box-type structure is used, so asampling depth is precision, and an area is accurate. The separating hole is reserved in the moveable vertical plate of the box part, and the separating plate is used for separating samples hierarchically, and a mud layer sequence is maintained, so the distribution hierarchy of benthonic animals in a mu sample is conveniently analyzed. The moveable vertical plate is used for, according to the sampling requirements, manufacturing the moveable vertical plate reserved with the different depths of the separating holes, and satisfying the different sampling hierarchical requirements.

Description

Technical field: [0001] The invention relates to the research of benthic animals in the intertidal zone, and belongs to the technical field of marine biology research, in particular to a layered sampler for benthic animals in the intertidal zone. Background technique: [0002] The intertidal zone is an important type of tidal wetland ecosystem, and the ecological environment is complex and changeable. Therefore, the study of intertidal zone ecology has been receiving much attention. As an important part of the intertidal wetland ecosystem, benthic animals have always been a hot spot in ecological research, and it is necessary to sample and analyze the benthic animals in the intertidal zone. In order to improve the accuracy of observation and analysis, it is not only necessary to collect a certain number of samples, but also to keep the samples in their original state. [0003] At present, the tidal flat quantitative sampling frame is required for sampling and analyzing sedi...
