Sample device suitable for investigation of aquatic plant resources and application method thereof

Abstract

The invention discloses a sample device suitable for investigation of aquatic plant resources and application method thereof. The sample device includes a telescopic rod and a sample box mounted on the telescopic rod. The telescopic rod is composed of a rod set with different outer diameters and can be telescopically deployed. The upper and lower ends of the telescopic rod are further provided with strut nuts, and the upper and lower ends of the telescopic rod are mounted with detachable fixing cones through the strut nuts. The sample box is installed by employing a double clamp module matchedwith the telescopic rod in the outer diameter on the telescopic rod, the sample box is fixed at the surface of the water body at different depths, even though in a condition of the rapid flow, the location operation of the sample can be achieved; and the hollow sample box frame made of the PVC materials and the processing mode of a bending tube and a rubber plug are convenient for floating waterfixing; and moreover, the sleeving mode of the telescopic rod, the detachable fixing cones and the sample rod bending tube is convenient to use and easy to install and carry in the field.

Description

Technical field [0001] The invention relates to the field of investigation of aquatic plant resources in aquatic ecosystems, and relates to a sample device suitable for aquatic plant resources and a use method thereof. Background technique [0002] Community species diversity is an important content in the study of plant community ecology. It is a comprehensive reflection of plant species abundance and distribution uniformity. It reflects the type of community structure, organization level, development stage, stability and habitat differences. Through the investigation and study of plant samples and the comprehensive analysis of plant communities, it is possible to find out the relationship between various communities and the relationship between the characteristics of the community itself and the ecological environment. [0003] Sample plots are randomly set sampling plots for investigating the number of plant communities. Different plant communities have different plot areas. I...
