[0002] With the rapid growth of the national economy and the significant improvement of people's living standards, great progress has been made in environmental protection through unremitting efforts, but the overall severe situation of water environment has not fundamentally changed. The main reasons are that the amount of pollutants discharged exceeds the carrying capacity of the water environment, river water is polluted, lakes are eutrophic, the ecology is seriously damaged, biodiversity is reduced, and the function of the ecosystem is degraded, which restricts economic and social development, endangers people's health, and affects social and environmental security.

[0003] Water ecological restoration is to restore and repair the degraded or damaged water ecosystem through a series of measures, basically reaching the original level or exceeding the original level, and maintaining its long-term stability. The purpose of water ecological restoration is to repair and restore the original biodiversity and continuity of the water body, give full play to the production potential of resources, and at the same time protect the water environment, so that the water ecosystem can enter a virtuous cycle and achieve synchronous economic and ecological development.

[0004] In order to achieve the important goal of water ecological environment protection, it is necessary to evaluate the water pollution status through water quality and plankton monitoring, and propose targeted protection and restoration measures.
