Ecological niche complementary restoration method for fishery excessive fishing lake

Abstract

The invention discloses an ecological niche complementary restoration method for a fishery excessive fishing lake, and belongs to the field of lake ecological niche restoration methods. According to the ecological niche complementary restoration method for the fishery excessive fishing lake, the artificial intervention in the ecological restoration work can be realized, technicians can control theprogress of ecological restoration by themselves, and the controllable ecosystem restoration by technicians is realized. The ecological niche of the exhausted ecological niche species is temporarilyfilled by putting a proper amount of complementary species into an ecological system, namely the food is provided for the high ecological niche species, the overgrowth of low ecological niche speciesis effectively inhibited, and during the ecological restoration process, the complementary species are monitored in real time, so that the biological invasion phenomenon caused by the excessive growthof the complementary species is avoided, the direct collapse of the ecological system is avoided, the randomness during the ecological system restoration process is reduced, the restoration speed ofthe ecological system is greatly increased, and the working difficulty of the technicians is greatly reduced.

Description

technical field [0001] The invention relates to the field of lake ecological niche restoration methods, in particular to a ecological niche complementary restoration method for fishery overfished lakes. Background technique [0002] Ecological niche refers to the position of a population in the ecosystem in terms of time and space and its functional relationship and role with related populations. The ecological niche is also called an ecological niche, which means that each organism in the ecosystem must survive. Habitat minimum threshold. In ecological balance, the ecological niches of various organisms do not overlap in principle. If there is overlap, it must be unstable. It will inevitably reduce the overlap of ecological niches through competition among species until it is balanced. Competition, such as requiring similar ecological The entry of some invasive species will lead to the reduction of the area where indigenous species exist. If the area is too small, it will ...

AI Technical Summary

Problems solved by technology

[0004] In real life, in a single lake ecosystem, species with high economic value usually have only a small number of tree species, and these species are usually the primary targets of people's fishing. Organisms in one or a few ecological niches will be overfished. Although the organisms in other ecological niches have not undergone large changes due to human fishing, with the loss of one or some ecological systems in the ecosystem, the entire ecosystem will be overfished. The energy transmission of the ecosystem is not smooth, or the organisms in the low niche grow wildly, or the organisms in the high niche die in large numbers due to the lack of food, which leads to the collapse of the entire ecosystem

[0005] However, most of the restoration methods of the current technology to the ecosystem are to remove human interference factors in the ecosystem, so that the organisms in each ecological niche in the ecosystem can rebuild the ecological relationship of restriction and mutual existence, so that the ecosystem can become stable again. Although the investment in the method is small, the restoration time is long, and the restoration of the ecosystem cannot be completed quickly, and there is obvious randomness in the process of natural restoration, it is difficult for people to control the restoration progress of the ecosystem, and it is difficult to carry out a controllable ecosystem repair
