Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0027] A food chain reconstruction method for lake water ecological management, using the break of the original food web, the construction of the new food web, and the maintenance and management of the food web to establish a reasonable pyramid energy transfer model. Its characteristics: stable and long-lasting effect, assisting the construction of submerged plant system, restoring the self-regulating ability of the lake, beautifying the environment and ecological education. specifically:

[0028] Breaking the original food web includes reducing the stock and proportion of the original small and omnivorous fish by driving, fishing, and stocking large carnivorous fish for predation. Avoid excessive bottom-stirring and water-stirring fish that cause turbid water quality and are not easy to settle. The transp...

Abstract

The invention discloses a food chain reconstruction method for lake water ecological management. The invention utilizes original food web breaking, new food web construction, and food web maintenance and management to establish a reasonable pyramid energy transfer mode; and reduces the stock and proportion of original small and omnivorous fish by driving, fishing, and stocking of large carnivorous fish for predation. The method avoids water turbidity caused by agitation of excessive bottom agitating and water agitating fish and difficult sedimentation, low water transparency, insufficient illumination needed by plants, and plant growth inhibition or even death, and kills harmful pathogens and larvae able to cause illness of submerged plants and fish in wate and sediment. The method provided by the invention has stable and lasting effects, assists construction of a submerged plant system, improves lake's recovery of self-adjustment ability, and beautifies the environment.

Description

technical field [0001] The invention relates to the technical field of environmental governance, in particular to a food chain reconstruction method for lake water ecological governance. Background technique [0002] With the development of society and the continuous improvement of people's living standards, most landscape lakes are located in densely populated places and are subject to greater pollution threats. Moreover, most of the lakes used to be important places for aquaculture, and most of them were dominated by the four major domestic fishes. Therefore, in order to ensure high production, carnivorous fishes were strictly controlled. When people's living standards are getting higher and higher, the deteriorating water environment has been widely criticized, so many places in China have introduced policies to ban rivers, lakes, cages, prohibit fertilization and fish farming, and to build water ecological civilization and water environment governance. Combine it with p...
