Ecological riverside zone of navigable river channel

Abstract

The invention discloses an ecological riverside zone of a navigable river channel. The riverside zone comprises an ecological purification section and an animal channel compensation section which arearranged at intervals along the river channel; the ecological purification section is provided with an ecological anti-impact zone (30), a retaining wall (31) and a wave dissipation purification wetland (32); the animal channel compensation section is provided with a biological buffer passage (20) and a biological buffer pond (21); a land area transition zone (4) is arranged behind the ecologicalpurification section and the animal channel compensation section; and a water-permeable pile body (201) is arranged on the biological buffer channel (20). According to the ecological riverside zone, water and soil of a bank slope can be protected, a ship wave can be reduced, so that sites for foraging and inhabiting are provided for aquatic animals such as fishes, shrimps, shellfishes and snails;meanwhile, an amphibious animal channel is also arranged, so that living space for the amphibious animals is guaranteed; and the effects of filling filtration, plant absorption and the like are utilized, so that the pollution load in a water body is reduced, and therefore the normal growth of riverside wetland plants and purification of the water quality in the river channel are guaranteed.

Description

technical field [0001] The invention relates to the technical field of a riverside belt, in particular to an ecological riverside belt. Background technique [0002] With the development of shipping economy, more and more natural waterways are developed into shipping channels, and the more waterway resources are utilized, the greater the impact on the environment. There are many ships passing by in the navigable river, and the waves generated by the ships sailing have a strong scouring effect on the shoreline. In order to ensure the safety of the passage, upright hard concrete retaining walls are basically used on both sides of the river to ensure the safety of the ship. water depth and slope stability. However, the concrete structure will cause a severe situation such as the obvious reduction of wetlands, the obvious reduction of biodiversity, and the serious degradation of ecosystems. At the same time, the upright hard concrete retaining wall that is much higher than the...
