Method for recovering submerged plant communities in polluted fresh water area

Abstract

The invention belongs to the field of environmental protection, and particularly relates to a method for recovering submerged plant communities in a polluted fresh water area. The method comprises thefollowing steps that after the composition of submerged plant communities planted in a target water area is determined, according to staged scheme, in a first stage, submerged plant species are planted for collocation and combination; after planting of the submerged plant species in the first stage is completed, the current water depth serves as the light compensation depth of submerged plant restoration in a second stage, and if the transparency under the light compensation depth is larger than or equal to the actual transparency, submerged plant combinations of medium stain-resistant and sensitive species in the second stage are arranged and planted, so that a good submerged plant restoration effect is achieved.

Description

technical field

[0001] The invention belongs to the field of environmental protection, and in particular relates to a recovery method for submerged plant communities in polluted fresh water areas. Background technique

[0002] There are only 3% of the fresh water resources on the earth, most of which come from Antarctic solid glaciers, and a small part comes from groundwater and freshwater lakes, and freshwater lakes are of great significance to the ecological environment. The ecological environment of my country's freshwater lakes continues to deteriorate, and the water level and water environment quality continue to decline, resulting in the loss of species and the decline in biodiversity, which seriously affects the production and life of local residents, and brings a negative impact on the balance of the local ecosystem and the sustainable development of the region. Great threat. Therefore, managing freshwater lakes and realizing the sustainable development of freshwater...
