Embodiment 1

[0032] (1) Analysis of the main environmental factors affecting floating plants

[0033] Wind and waves have a major impact on the growth of floating plants, causing direct mechanical damage. If effective measures are not taken, it will be difficult for plants to grow in the wind and wave area of ​​the lake. Experiments have shown that the introduction of Litella philodendron into the enclosure, the coverage is 100%, and the cumulative loss reaches 60% in less than a month, which shows that it is not easy to restore floating plants in the stormy area of ​​the lake. This is due to the up-and-down motion of the waves, which causes the roots, stems and leaves of floating plants to move relative to each other and damage each other. In the natural state, the amount of damage is much greater than the amount of growth, so it is almost impossible to survive normally. There is no precedent for long-term successful cultivation. Therefore, the implementation of wave suppression projects...

Embodiment 2

[0051] Compared with Example 1, the only difference is that the concrete piles adopt a single row of piles, the piles are arranged in a diamond shape in the direction of facing waves, and the distance between two adjacent piles is 10cm. The observation results show that the wave penetration rate of the single row of piles for various wave heights is between 0.63-0.74, and the wave dissipation effect is significantly lower than that of Example 1. Therefore, the layout of double-row concrete piles is more conducive to wave dissipation.

Embodiment 3

[0053] Compared with Example 1, the only difference is that the distance between the two piles in the front row is 50cm, the piles in the back row are inserted evenly between the piles in the front row in turn, and the distance between the piles in the front row and the pile row direction is It is 10cm. Observation found that the wave transmission rate of this interspersed concrete pile laying method is above 0.7, which is significantly higher than that of Example 1. Therefore, it is better to arrange the concrete piles in two rows and maintain a certain distance between them.

Abstract

The invention belongs to the technical field of ecological restoration and provides a wave-elimination technology for improving the basic environment of aquatic plant restoration in large shallow lakes. In view of the characteristics of large shallow lakes with large wind and wave disturbances, the invention uses engineering wave dissipation components including concrete piles and bamboo rafts. The concrete piles are arranged on the periphery of the defense area to resist the attack of extremely large wind and waves, and cooperate with the inner bamboo raft components to enhance the defense effect. Concrete pile components are interlaced to form a wave-dissipating belt, and the generated friction of blocking, reflecting, breaking waves and water and piles reduces the waves in the target area; Waves create breaking waves. This design can reduce the impact of lake wind and waves, control sediment resuspension, provide basic environmental conditions for the restoration of lake aquatic plants, and achieve the goal of improving water quality.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and relates to a wave dissipation method for improving the basic environment of large shallow lakes. Background technique [0002] Wind and waves have very complex effects on aquatic higher plants. The survey found that the higher aquatic plants in Taihu Lake are generally distributed in the coast, bays and other waters, and the water depth is generally within 2m. In open water areas, it is difficult to have higher aquatic plants. Only in lakes and bays and other waters with less wind and waves in Taihu Lake can higher aquatic plants grow and develop; while in open waters such as West Taihu Lake, almost no aquatic higher plants can be seen, only occasionally found on the edge of the net where fishermen cast their nets Sporadic submerged plants, or only when the surrounding environment undergoes essential changes, will aquatic higher plants grow. [0003] Wind and waves have dire...
