(1) technical field
The Ecological pyramid and application that the present invention relates to a kind of for administering eutrophic water body.
(2) background technique
Since summer sunshine is strong, surface water body (river, pond, lake etc.) algae excessive propagation of eutrophication, one
The food chain of serial heterotrophic organism also rapidly develops therewith, and water body epiplankton density is excessively high, and ecology is active, and oxygen consumption is significantly
Increase.And water bottom then in default of illumination, dissolved oxygen and it is gradually anaerobic, benthon is dead.Benthon is water body
The important link of ecological material circulation, the algae of heavy water type is the important sources that water body photosynthesis produces oxygen, and zoobenthos, such as
Spiral shell, freshwater mussel, shellfish etc. are food with planktonic organism, are the important algae consumer organisms except filter-feeding fish (silver carp, flathead etc.).Water body bottom
Portion's dissolved oxygen reduces, and benthon living environment deteriorates, and biomass is reduced, and organic matter conversion capability, which will weaken, even to disappear.
Chen Yuxia etc. reviewed benthic mollusc in 2010 to the importance of water environment ecology, and had collected and manually reseed bottom and dwell life
Studies in China that object repairs water ecology and using status.
Therefore, eutrophication water body water quality deteriorates smelly problem core, is water body organism in suitable temperature, nitrogen phosphorus
Under the integrated condition that equal plant nutrients content is high, illumination is strong, output is greatly increased.And water surface ecology enliven,
It instead results in benthic living environment to deteriorate, the ability of water body organism conversion is suppressed, or destroys completely.Water body
The organic matter of surface layer synthesis cannot be converted effectively, be deposited on water bottom serious accumulation, corruption, water ecology is by whole
Serious destruction on body.
It dwells the insufficient situation of bioactivity for water eutrophication state bottom, forefathers propose many improved technology sides
Case.Such as leaf army, Liu Lusan, Henan propose artificial mend and educate benthic mollusc or submerged plant and bottom software of dwelling is dynamic
The ecological recovery scheme that object combines.But these technical solutions are all that in-situ immobilization is carried out in water body, by water body natural conditions
Limitation, especially benthic mollusc stand density limitation, on limited riverbed, lakebed area, growth bottom dwell
Biological total amount is limited, to limit the biomass manually launched.And the water body for being in thanks to oxygen condition, then people
Work dispensing benthon is not only nonsensical, and death rots also be further exacerbated by water pollution.
(3) summary of the invention
The Ecological pyramid and application that it is an object of the present invention to provide a kind of for administering eutrophic water body, dwell soft in conjunction with filter bed and bottom
