Problems solved by technology

Although the device is suitable for shallow water areas, it is not suitable for deep water areas
At the same time, the device cannot quantitatively collect submerged plants, so it is not suitable for the estimation of submerged plant biomass

Embodiment 1

[0043]A quantitative investigation device for submerged plants in lakes and reservoirs, including a traction rope, an automatic rope release hook and a grass grabbing bucket; the automatic rope release hook includes a flat plate and a hook plate, each end of the flat plate is provided with a connection port, and the traction rope passes through a connection port Connected with the flat plate; one end of the hook plate is provided with a hook head, and the hook plate is hinged to the flat plate; the grass grabbing bucket includes two grabs, which are used to grab aquatic plants, and the opposite ends of the two grabs are hingedly connected, and a steel wire rope is provided at the hinge The grabbing bucket is connected to the other connection port of the flat plate through the steel wire rope at the hinge; the ends of the two grab buckets are connected together through the steel wire rope.

Embodiment 2

[0045] A quantitative investigation device for submerged plants in lakes and reservoirs, the structure of which is as described in Example 1, the difference is that the grab bucket includes two grab jaw plates, and a bucket wall is connected between the two grab bucket jaw plates. One end of the two grab jaw plates is connected with a bucket bottom. Two grapples each are so composed.

Embodiment 3

[0047] A quantitative investigation device for submerged plants in lakes and reservoirs, its structure is as described in Example 2, the difference is that the jaw plate of the grab bucket is a fan-shaped plate with a cross-sectional area of ​​one-eighth, and the arc of the two fan-shaped plates The ends are connected with a bucket bottom, and the respective diameter sides of the two fan-shaped plates are connected with a bucket wall. Two grab jaw plates, a bucket wall, and a bucket bottom are combined to form a grab bucket with a cavity that can grab and place plants. The fan-shaped plate has two diameter sides, and the bucket wall is only set at one diameter side. The two fan-shaped The other diameter side of the plate is open to serve as the opening of the grab cavity.

Abstract

The invention relates to a quantitative survey device for submerged plants in lakes and reservoirs and a survey method, and belongs to the technical field of water metering devices. The quantitative survey device comprises a drag rope, an automatic rope releasing hook and a grass grasping bucket, wherein the automatic rope releasing hook comprises a flat plate and a hook plate; the drag rope is connected with the flat plate; a hook head is arranged at one end of the hook plate; the hook plate is articulated with the flat plate; the grass grasping bucket comprises two grasping buckets; the grasping buckets are used for grasping and containing aquatic plants; opposite ends of the two grasping buckets are articulated with each other; a steel wire rope is arranged in an articulated position; the grass grasping bucket is connected with the flat plate through the steel wire rope in the articulated position; the ends, which are far from each other, of the two grasping buckets are connected with each other through a steel wire rope. Submerged vegetation is grasped by the device in a sampling area in a lake or a reservoir, and the community biomass and diversity of the submerged plants in sampling water are computed. The quantitative survey device can more accurately calculate the biomass and coverage rate of submerged plants in lakes and reservoirs, and more comprehensively understandthe community structure and species diversity of the submerged plants in lakes and reservoirs.

Description

technical field [0001] The invention relates to a quantitative investigation device and investigation method for submerged plants in lakes and reservoirs, and belongs to the technical field of water metering devices. Background technique [0002] Aquatic vegetation plays a pivotal role in the construction, balance, maintenance and restoration of the entire water ecosystem. First, as a primary producer, it directly or indirectly provides the food base for various aquatic animals, and then forms a complex food chain, which provides the necessary conditions for the final formation of a complex ecosystem; secondly, regulates the material cycle of the ecosystem and maintains the ecosystem virtuous circle; again, large aquatic plants compete with phytoplankton for nutrients and growth space, as well as the formation of shading effects and secretion of algal substances, which can well inhibit the excessive reproduction of algae and maintain high biodiversity and health.
