Bank protection and wave dissipation method for lakeside zone of natural large water area based on recovery of submerged vegetation

Abstract

The invention provides a bank protection and wave dissipation method for a lakeside zone of a natural large water area based on recovery of submerged vegetation. According to the invention, a lakeside shore base is used as a boundary, and a water separation blocking net, a tea tree zone arranged in an inverted insertion shape and a submerged plant zone arranged between the lakeside shore base and the tea tree zone are sequentially arranged from outside to inside to form a bank protection and wave dissipation structure for the lakeside zone of the natural large water area; the bottom of the water separation blocking net is fixed with a lakeside base through inserting rods arranged at certain intervals, and a plurality of floating balls are arranged between the adjacent inserting rods located at the upper part of the water separation blocking net; the water separation blocking net is composed of two layers of net bodies, the hole diameters of meshes on the outer layer are in a range of 5-8 mm, and the hole diameters of meshes on the inner layer are in a range of 2-5 mm; and the tea tree zone is composed of at least two rows of tea trees with single tea trees in one row being alternate with single tea trees in the other row, the height of the tea trees exposed out of a water surface is smaller than the height of the water separation blocking net exposed out of the water surface, or the height of the tea trees is 40-80 cm higher than the normal water level of a water body throughout the year, and a distance between every two adjacent tea trees are 3/5-4/5 of the tree-shaped crown breadth exposed out of 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...

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
