Repair method of hard slope submerged plants

Abstract

The invention relates to a repair method of hard slope submerged plants. The invention adopts the technical scheme that the method comprises the following steps of: filling matrix required by the growth of submerged plants in planting cylinders, planting the submerged plants according to the seasonal variation, connecting a plurality of planting cylinders side by side in series by using connecting ropes to form a row type planting carrier, and fixing the planting carrier on a riparian zone bank slope by using anchor piles. The planting carrier can be well fixed on the riparian zone, so that wind wave impact is resisted, the stability of the carrier is kept, the matrix condition required by the growth of the submerged plants is provided, meanwhile, the loss of the nutritional matrix can be reduced, and the survival rate of the submerged plants is improved; and the method is low in cost, convenient to implement and remarkable in effect, and is favorable for coordination of riparian ecological conservation function, water purification function and landscape beautification function.

Description

technical field [0001] The invention relates to the technical field of river and lake ecological restoration engineering, in particular to a restoration method for submerged plants on hard slopes. Background technique [0002] The waterfront zone includes the entire zone from the junction of water and land to the disappearance of the influence of the river water. It is one of the main types of ecological ecotones. It has the functions of holding pollutants, preventing river bank erosion, improving air quality, maintaining water circulation, protecting vegetation communities, and communicating with others. Functions such as system connection and providing habitats for animals and plants have extremely high ecological, environmental and landscape values. However, the implementation of "straightening", "hardening" and "smoothing" projects in river and lake renovation has made river and lake bank slopes become hard slope protection, and the aquatic plant community in the waterfr...

AI Technical Summary

Problems solved by technology

[0005] Submerged plants have high requirements on the environment, and their growth is affected by many factors, such as substrate conditions, light intensity, transparency, suspended particles, water flow, wind and waves, etc. The restoration of submerged plants in water bodies is a technical problem in itself, and in " It is more difficult to restore submerged plants on the hard slopes of waterfronts that are straight, hard, or smooth

First of all, the hard slopes along the waterfront are all hard and smooth concrete, and there is no matrix condition suitable for the growth of submerged plants; moreover, the waterfront area is greatly affected by wind and waves, and general submerged plant restoration techniques (such as planting by cuttings) method, throwing planting method, heavy planting method, sunken bed planting method, container planting method, etc.) cannot solve the problems such as big wind and waves, planting carrier is difficult to fix and easily damaged, and the existing submerged plant planting carrier generally has high cost, The survival rate of submerged plants is not high, and the carrier is easy to age, etc.
