A bank revetment and wave dissipation method for lakeside belts in natural large waters based on submerged vegetation restoration

Abstract

A bank revetment and wave dissipation method based on the restoration of submerged vegetation in natural large waters lakeside. With the lakeshore foundation as the boundary, water barriers, tea tree belts arranged in an inverted shape, and tea tree belts arranged in the lakeshore foundation and tea trees are sequentially arranged from the outside to the inside. The submerged plant belts between the belts constitute the bank protection and wave dissipation structure of the natural large water area lake; The ball; the water-proof fence net is composed of two layers of nets, the outer mesh aperture is 5-8mm, and the inner mesh aperture is 2-5mm; the tea tree belt is composed of at least two rows of tea trees interspersed with each other, and the tea trees are out of the water The height of the fence should be less than the height above the water surface of the water barrier, or set at 40-80cm higher than the normal water level of the water body, and it is advisable for each two adjacent plants to have 3 / 5-4 / 5 of the tree-like crown width of the part exposed to the water surface.

Description

technical field [0001] The present invention relates to a method for improving the survivability of submerged vegetation and reducing the impact of wind and waves, in particular to a method for revetment and wave dissipation of lakeside belts in natural large waters based on the restoration of submerged vegetation, which is suitable for submerged vegetation used in large natural waters with many storms Restoration tape is used to dissipate waves. Background technique [0002] At present, the revetment measures mainly adopt two forms: engineering revetment and plant revetment; although engineering revetment has the characteristics of stability, it not only has adverse effects on the maintenance of ecological environment and natural landscape to varying degrees, but also is not conducive to the concept of circular economy; therefore Mainly consider the form of plant revetment. In the application of plant revetment technology, more revetment plants are used, such as river will...

AI Technical Summary

Problems solved by technology

At present, engineering measures such as soft enclosures, bamboo rafts, and riprap cofferdams are widely used in large natural waters to eliminate waves, which not only have high engineering costs, strong ecological barriers, and are not conducive to the natural reproduction of submerged vegetation and succession development
