Problems solved by technology

[0002] Compared with deep-water lakes, shallow-water lakes do not have long-term stable temperature stratification, and the water-soil interface area per unit volume of water body is large. Wind waves have a strong disturbance effect on lake sediments, and unconsolidated surface sediments are frequently resuspended; shore The boundary between the zone and the open water area is blurred, and the structure of the water ecosystem is complex; the circulation mechanism of nutrients in the ecosystem is complicated, and the circulation rate of nutrients is relatively fast

Embodiment 1

[0023] Specific as figure 1 , 2 , 3, and 4, in a lake with an average water depth of 3.0m, a shallow lake deep-water area 5 is formed by excavating the sediment a1-1. The excavation depth is 1m, and the excavated sediment a1-1 is buried in In other areas of the lake, the sediment b1-2 formed after the sediment a1-1 is transported is further accumulated to form a shallow water area 4, which reconstructs the bottom landform of a shallow-water lake.

[0024] In the lakeside zone 3, where the average water depth is less than or equal to 0.5m, a windbreak zone of emergent plants 9 shall be established to reduce wind disturbance to the lake water, improve the retention environment and living space of microorganisms and aquatic organisms in the lakeside zone 3, and effectively improve the water environment quality of coastal waters.

[0025] In the shallow water area 4, the bottom of the lake is selected to be flat, and the submerged plants 6 are transplanted in the water area with ...

Embodiment 2

[0032] Specific as figure 1 , 2 As shown in , 3 and 4, in a lake with an average water depth of 2.0m, the deep-water area 5 of a shallow lake is formed by excavating the sediment a1-1. The excavation depth is 5m, and the sediment a1-1 obtained from the excavation is buried in In other areas of the lake, the sediment b1-2 formed after the sediment a1-1 is transported is further accumulated to form a shallow water area 4, which reconstructs the bottom landform of a shallow-water lake.

[0033]In the lakeside zone 3, where the average water depth is less than or equal to 0.5m, a windbreak zone of emergent plants 9 shall be established to reduce wind disturbance to the lake water, improve the retention environment and living space of microorganisms and aquatic organisms in the lakeside zone 3, and effectively improve the water environment quality of coastal waters.

Embodiment 3

[0041] Specific as figure 1 , 2 , 3, and 4, in a lake with an average water depth of 1.5m, a shallow lake deep-water area 5 is formed by excavating the sediment a1-1. The excavation depth is 10m, and the excavated sediment a1-1 is buried in In other areas of the lake, the sediment b1-2 formed after the sediment a1-1 is transported is further accumulated to form a shallow water area 4, which reconstructs the bottom landform of a shallow-water lake.

[0042] In the lakeside zone 3, where the average water depth is less than or equal to 0.5m, a windbreak zone of emergent plants 9 shall be established to reduce wind disturbance to the lake water, improve the retention environment and living space of microorganisms and aquatic organisms in the lakeside zone 3, and effectively improve the water environment quality of coastal waters.

Abstract

The invention relates to a large shallow lake deep and shallow bottom layer landform reconstruction and benign stable ecosystem which is characterized in that bottom mud a is excavated to form a shallow water type lake deep water area, the excavated bottom mud a is buried in other areas of the lake, bottom mud b formed after the bottom mud a is conveyed is accumulated to form a shallow water area, the periphery of the shallow water area is a lakeside zone, the lakeside zone is located in a land and water interlaced zone of the shallow lake, ecological reefs are put in the deep water zone, submerged plants and ornamental lophatherum gracile are planted in the shallow water zone, and emergent aquatic plants are planted in the lakeside zone. The ecological principle is utilized, and the self-cleaning capacity of the shallow lake is restored by reconstructing deep and shallow bottom layer landforms, constructing a biocenosis structure of a damaged water body ecological system and restoring biodiversity, so that the virtuous circle of self-maintenance and self-succession of the ecological system is realized.

Description

technical field [0001] The invention relates to a large-scale shallow-water lake reconstructing deep and shallow bottom landforms and a benign and stable ecological system. Background technique [0002] Compared with deep-water lakes, shallow-water lakes do not have long-term stable temperature stratification, and the water-soil interface area per unit volume of water body is large. Wind waves have a strong disturbance effect on lake sediments, and unconsolidated surface sediments are frequently resuspended; shore The boundary between the zone and the open water area is blurred, and the structure of the water ecosystem is complex; the circulation mechanism of nutrients in the ecosystem is complicated, and the circulation rate of nutrients is relatively fast. Contents of the invention [0003] The purpose of the present invention is to address the existing problems, to provide a large shallow lake to reconstruct the deep and shallow bottom landform and benign and stable eco...
