Embodiment Construction
[0037] As shown in the accompanying drawing, the ecological restoration system of a kind of replenishment-type river course in this embodiment constructs an ecological riverbed based on the existing replenishment-type river course. , 3 deep pools at the entrance, 4 rock groups, shoal deep pools, 6 overflow dams, 7 wooden pile groups, 8 fish nests and 9 biological passages. The entrance deep pool 3 is set at the downstream of the upstream water replenishment port 2, the block stone group 4 is set at the downstream of the entrance deep pool 3, the shoal deep pool 5, the overflow dam 6, the pile group 7, the fish nest 8 and the biological channel 9 along the river Channel distribution settings. Plant trees on the river slope protection, and plant aquatic plants in the shallows.
[0038] In this embodiment, the preferred removal of sediment and river garbage in the river channel is to use an excavator to remove the silt, and the method of manual dredging is adopted within 50 cm o...

Abstract
The invention provides an ecological restoration system of water complement type river channel. The ecological restoration system of the water complement type river channel aims to overcome the shortcomings that a virtuous circle cannot be formed due to biological invasion, deterioration of water quality and the like since diverse ecological systems cannot be established in complement water type river channels in the prior art, and based on an existing water complement type river channel, an ecological river bed is constructed. The ecological restoration system includes the water complement type river channel, and an upstream water complement opening, an entrance deep pool, rock block groups, shoal and deep pool groups, an overflow dam, wooden pile groups, fish nests and biological channels, wherein the upstream complement water opening, the entrance deep pool, the rock block groups, the shoal and deep pool groups, the overflow dam, the wooden pile groups, the fish nests and the biological channels are arranged in the river channel; the entrance deep pool is arranged on the downstream part of the upstream complement water opening, the rock block groups are arranged on the downstream part of the entrance deep pool, the shoal and deep pool groups, the overflow dam, the wooden pile groups, the fish nests and the biological channels are arranged along the river channel in a distributed mode; and trees are planted on river channel slope protection, and water plants are planted in shoals. According to the ecological restoration system of the water complement type river channel, the biodiversity is restored, the water environment is improved, and using in the water complement type river channel is suitable.
Description
technical field [0001] The invention relates to the field of water quality control, in particular to an ecological restoration system of a water supply type river course. Background technique [0002] With the water quality pollution of urban rivers and the construction of water conservancy facilities, the natural landform characteristics of urban rivers have changed significantly. The channelization of rivers, the hardening of river banks and the lack of river landscape have destroyed the ecological system of natural rivers and reduced the ecological environment carrying capacity of rivers. . Although sewage interception has been completed and water quality has been improved in replenishment-type rivers, due to the lack of habitats suitable for living organisms, a diverse ecosystem cannot be established. In the long run, it will lead to problems such as biological invasion and water quality deterioration, and cannot form a virtuous circle. Contents of the invention [00...
