Riverway ecological environment protection and restoration method

Abstract

The invention discloses a riverway ecological environment protection and restoration method which comprises the following steps: repairing an artificial wetland, making up the lack of the wetland in an earth cutting and landfill manner, planting aquatic plants such as yellow flag and reed in the wetland range, and performing separated protection and treatment on the wetland through the construction of an amphibious transition zone until a certain effect is generated in the treatment of the area; meanwhile, in wetland construction engineering, organic combination of the ecological environment and urban landscape is fully considered, and the landscape effect of the wetland is enriched by planting cinnamomum camphora, metasequoia, weeping willow, yellow flag , spiked loosestrife herb and thelike; the reason why the water quality of the riverway is damaged is not merely random discharge of waste water; according to the invention, through repairing the constructed wetland, implementing artificial oxygenation, repairing the ecological floating island, treating a pollution source, improving water quality, designing bank slope protection and designing a cross section, the burden of the river channel is reduced, and the ecological stable development of the river channel is ensured.

Description

technical field [0001] The invention relates to the technical field of ecological management, in particular to a method for protecting and restoring the ecological environment of a river course. Background technique [0002] Nowadays, more and more rivers run through various cities. Urban river management and environmental restoration have become topics of concern to all sectors of society. Or it is of great significance to environmental restoration, because there are many problems in urban rivers, which have seriously affected its function. [0003] The actual river revetment uses mortar or dry stone retaining wall revetment without ecological effect, cast-in-place concrete retaining wall revetment, prefabricated concrete block revetment, etc. The traditional revetment seals the entire river bank surface and isolates the soil from the water. The exchange of materials between them affects the ecological balance; therefore, it is necessary to design a method for the protecti...

Or it is of great significance to environmental restoration, because there are many problems in urban rivers, which have seriously affected its function.

[0003] The actual river revetment uses mortar or dry stone retaining wall revetment without ecological effect, cast-in-place concrete retaining wall revetment, prefabricated concrete block revetment, etc. The traditional revetment seals the entire river bank surface and isolates the soil from the water. The material exchange between them affects the ecological balance; therefore, it is necessary to design a method for the protection and restoration of the river ecological environment
