Ecological floating bed and method for recovering eutrophic reservoir aquatic ecosystem by utilizing floating bed

Abstract

The invention provides an ecological floating bed and a method for recovering a eutrophic reservoir aquatic ecosystem by utilizing the floating bed. The ecological floating bed comprises a floating bed body located on the water surface, a net cage which is located at the lower part of the floating bed body and a hanging cup located in the net cage, wherein the floating bed body is formed by combining and connecting a plurality of floating blocks; the net cage is of a net-shaped structure and the upper end of the net cage is connected with the bottom of the floating bed body; the hanging cup is connected with the bottom of the floating bed body through a hanging rope; the floating bed body is used for culturing aquatic plants; the net cage is used for internally culturing aquatic animals; the hanging cup is used for internally culturing submerged plants; furthermore, the invention provides the method for recovering a water ecosystem of a eutrophic water reservoir by utilizing the floating bed. By adopting the ecological floating bed and the method for recovering the eutrophic reservoir aquatic ecosystem by utilizing the floating bed, the ecosystem above the water surface can be effectively recovered and ecosystem reconstruction is carried out on the water body in a certain water depth range below the water surface, so that a complete water body ecosystem is easy to recover and the comprehensive utilization of water body resources is realized.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to an ecological floating bed and a method for restoring an eutrophic reservoir water ecosystem by using the floating bed. Background technique [0002] Up to now, my country has built a total of 85,849 reservoirs. The construction of reservoirs has changed the original hydrological cycle process of rivers and led to the degradation of ecosystems. [0003] The degradation of the ecological environment of the reservoir, on the one hand, reduces the self-purification capacity of the reservoir, causing terrestrial pollutants to directly enter the reservoir and accelerate the eutrophication of the water body, and the water quality declines, forming a vicious circle; The decline in fishery resources will directly affect the lives of immigrants and social and economic development in the reservoir area. At the same time, the degradation of the reservoir ecosystem will lead t...

Problems solved by technology

In the restoration of deep water ecosystems, ecological floating islands are mainly used. However, due to the relatively low nutrient salt in the reservoir water, the growth efficiency of ecological floating islands is low, and the existing ecological floating islands only build ecosystems above the water surface, so it is difficult Restoring complete aquatic ecosystems
