Algae bloom control method based on biologic chain relationship

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...

Problems solved by technology

Although various measures are taken to control wetland water eutrophication and slow down the frequency of algae blooms, whether it is source control (such as non-point source pollution control and sediment dredging, etc.) to reduce nutrient load, or adopt various algae removal measures (such as Artificial salvage and algicides, etc.), failed to achieve the expected results or were only effective in the short term, and some of them exacerbated the collapse of the fragile wetland ecosystem due to the use of improper physical or chemical methods
