Embodiment example

[0024] Example of the invention figure 1 It is used to illustrate the principle of an algae bloom control method based on the biological chain relationship. figure 1The biological chain structure aimed at controlling algae is established between various organisms in the forest through the relationship of predation and mutual restraint. Among them, Trichophyllum spicosa, Echinacea and Echinacea are enriched in the water body through growth, absorption, adsorption, and degradation. Nitrogen, phosphorus and harmful substances, block the sun's rays and release allelochemicals to control the outbreak of eutrophic water blooms (1); at the same time, use the filter-feeding effects of snails, silver carp, river mussels and crayfish to inhibit algae reproduction, In addition, you can also eat plants such as Trichosanthes spicatus, Cottonia chinensis and Eichhornia chinensis, so that they can continue to control the outbreak of water blooms in eutrophic water bodies (1). The structure ...

Abstract

The invention belongs to the technical field of ecological engineering and relates to an algae bloom control method based on a biologic chain relationship. The algae bloom control method disclosed by the invention is established by adopting food and inhibition relationships among organisms, so that the algae bloom outbreak in wetland water is inhibited. By adopting net-isolating floating island, composite layer net supporting floating island, wetland artificial planting technologies and aquatic animal stocking technologies, appropriate wetland organisms (including wetland plants and wetland animals) are selected according to the wetland hydrologic process and the seasonal variation characteristics, the algae bloom control method based on the biologic chain relationship disclosed by the invention is established and a complete wetland biologic chain structure is formed, so that the goal of controlling the algae bloom outbreak in the wetland water is achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering, and relates to a method for controlling algal blooms based on biological chain relationships. Background technique [0002] In the past 10 years, eutrophication and algae blooms have occurred frequently in wetland water. As the "kidney of the earth", the eutrophication of wetland water, the reduction of biodiversity and the vulnerability of biological chains have always been hot and difficult issues in the field of wetland science. With the development of human society and economy and the improvement of living standards, people's domestic water, industrial and agricultural water use have increased sharply, the eutrophication of wetland water has become increasingly serious, and algae blooms have occurred frequently, such as the Taihu Lake cyanobacteria bloom in 2007 and Chaohu Lake in 2010. Blue-green algae blooms have brought negative impacts on local production and life, serious...
