Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Embodiment, the recovery of submerged vegetation in the water area of ​​a certain area to be repaired around the lake, the specific steps are as follows:

[0024] Step 1: Screening of submerged plants, mainly to screen the species of native submerged plants. First, conduct a field survey on the water area of ​​a to-be-restored area around Taihu Lake, consult relevant literature, and set different underwater lighting conditions and water bodies according to the field survey results. Several submerged plants with strong water purification ability, low light resistance, pollution resistance, algae resistance and strong survivability were screened out by experimental research: sedge grass, bitter grass and thorn bitter grass. , thorny bitter grass, hornwort, foxtail algae, ricinacea, black algae, marigolds, microsaccharides, charcoal, and gra...

Abstract

The invention relates to the field of ecological restoration, in particular to a method for recovering submerged vegetation of a shallow lake ecosystem. The method comprises steps as follows: screening of submerged plants; rapid colonization of the submerged plants; optimal configuration of submerged plant communities; cooperative purification process of the submerged plants and aquatic animals. According to the method, growth characteristics and required environmental conditions of various submerged plants are taken into full consideration, the submerged plant communities are reasonably planted and configured, meanwhile, the aquatic animals are introduced, a damaged aquatic habitat is restored step by step, aquatic organismfood web (chain) is activated and maintained, a healthy ecosystemrealizingcooperative purification of aquatic organisms is constructed, and the method is simple to operate, lasting in effect and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the field of ecological restoration, in particular to a method for ecological restoration of submerged vegetation in shallow lakes. Background technique [0002] Biodiversity is a necessary condition for maintaining the stability of lake ecosystems, and in lake ecosystems, the diversity of wetland plants is conducive to maintaining a high self-purification capacity of lake ecosystems. [0003] Submerged plants refer to large aquatic plants whose plant bodies are all located under the water layer and live sessively. They are important primary producers in water bodies and an important part of lake ecosystems. have a significant impact. [0004] In recent decades, with the progress of society and the development of industrialization, the scale of cities has continued to expand, the population has increased, and a large amount of industrial and domestic sewage has been discharged into lakes without effective treatment, resulting ...
