Problems solved by technology

As far as submerged vegetation is concerned, due to the dynamic effect of water surface waves, there are difficulties in its reconstruction, such as plants are easy to be damaged, and they are easy to float freely with the water flow.
At present, the basic method is to manually harvest plants from healthy submerged vegetation areas, plant these plants at the bottom of the lake first, and then gradually release water to submerge the plants; this method can neither solve the problem of low plant survival rate nor solve the The problem of plants floating freely with the water flow leads to low recovery efficiency of submerged vegetation, which needs to be repaired continuously

Embodiment Construction

[0017] This method was demonstrated in the lake water body of the Taihu Lake Basin, and about 3500 square meters of lake submerged vegetation were obtained. Its specific implementation works as follows:

[0018] The first step is to conduct on-the-spot investigation and determine the height of water flow, water depth and light transmission depth; implement the seedling specifications and other construction materials of ecological tool species, and organize engineering and technical personnel to be in place.

[0019] In the second step, the seedlings and soil in the seedling training stage are taken out from the seedbed together, and clay is added to the outer layer of the soil so that the plant root system and the soil form a sphere.

[0020] The third step is to plant seedlings in the construction area according to the diameter of the circle. Each vegetation group is self-contained.

[0021] Finally, after the project is completed, the light transmittance of the water body ...

Abstract

A method for fast forming the community of submerged plant in lake features that 6 vegetation combinations of 4 local submerged plants in lake are planted in the lake.

Description

1. Technical field [0001] The invention belongs to the technical field of resources and environment engineering, and relates to a method for restoring submerged vegetation in lakes by using local species. 2. Background technology [0002] The natural lake ecosystem includes five parts: open water, submerged vegetation zone, floating leaf vegetation zone, emergent vegetation zone and lakeshore terrestrial vegetation zone. [0003] In my country, due to the increasingly serious eutrophication of water bodies in recent years, the submerged vegetation zone is also rapidly declining. The loss and degradation of vegetation as the primary productive force has led to the collapse of many lake water ecosystems, and the self-purification ability of lakes has basically disappeared. [0004] In view of this, while reducing the input of pollutants, restoring and rebuilding the collapsed aquatic communities and improving the self-purification capacity of lakes are the key to solving the ...
