Embodiment Construction

[0017] A method for ecological restoration of algae-type and eutrophic lake water, in which net frame fences 30 are set in the water area of ​​the lake to be repaired, water chestnuts are planted in rows in the water area enclosed by the net frame fences 30, and the transparency of the lake water is regularly tested. Tucked into the mud at the bottom of the lake, the leaves float on the water surface, and the water chestnut 16 can grow gradually with the rise of the water. From the basal stem of the bottom mud root system, through the root system and internode stems, it extends upwards, passes through the water body until the floating leaves form a water chestnut plate 11, and the rhomboid stem 16 16 lengths can reach 5 meters to 7 meters and each node of the water chestnut is full of water chestnut fibrous roots 13, so that each water chestnut 16 forms a three-dimensional fibrous root group in water (see figure 2 , figure 2 Among them, 12 is water chestnut, 14 is water ches...

Abstract

The invention provides an algae type and eutrophic lake water ecological restoration method for solving the problem that the existing water ecological restoration method is bad in restoration effect. The method is characterized by comprising the following steps: planting water chestnuts in lines in a to-be-restored lake water region, periodically detecting transparency of the lake water, when the transparency of the lake water is capable of meeting the requirement that a submerged plant can perform photosynthesis smoothly, planting the submerged plant between two adjacent lines of water chestnuts, controlling the planting coverage rate of the water chestnuts and the submerged plant, reducing the planting coverage rate of the water chestnut along the increase of the transparency of the lake water, and improving the planting coverage rate of the submerged plant through the transparency of the lake water.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the technical field of lake water environment protection, and specifically relates to an algae-type, eutrophic lake water ecological restoration method. Background technique [0002] Grass-type lakes and algae-type lakes are different stages in the process of lake succession. Grass-type lakes are lakes whose ecological environment has not been destroyed. There are a large number of aquatic vascular plants growing in their water bodies. A large number of vascular plants are destroyed, and at the same time, the water quality is too fertile to cause a large number of phytoplankton algae in the lake, resulting in eutrophication and gradual algae formation in grass-type lakes. The water body is turbid, and at the same time, the lake bottom lacks a protective layer. The wind and waves are more likely to roll up the sediment and make the water body more turbid, thus for...
