Description

A kind of method maintaining Landscape lake ecological balance
Technical field
The invention belongs to landscape lake ecological engineering field, be specifically related to a kind of side maintaining Landscape lake ecological balance Method.
Background technology
Landscape lake belongs to closed lake, both do not had circulating water, due to the scale of construction have big reason also cannot be to self water body Being replaced, therefore, Landscape lake easily produces water pollution.In order to Landscape lake is carried out water quality management and control, typically can In Landscape lake, throw in algivorous insect and plant planting submerged plant, but algivorous insect and submerged plant exist throws in asking of excess Topic, when algivorous insect throws in excess, algivorous insect is while the blue-green alge that ingests, and corruption of also ingesting is let out, float and noxious bacteria, can arrange Let out substantial amounts of nutrition secretions, make body eutrophication, during submerged plant excess, can be dead because of anoxia, corrupt, make water body Eutrophication, throws in, if can not eliminate, the impact that excess causes, water pollution occurs the most again.
Set up the mutual restriction of each species in ecological balanced system can realize waters, prevent asking of single class species excess Topic.The envelopes such as but current ecological balance biological renovation method is mainly used in flowing in waters, the most promising Landscape lake Close lake and enforcement reference is provided, and there is no the reference of concrete injected volume.
Summary of the invention
It is an object of the invention to provide a kind of method maintaining Landscape lake ecological balance, the method uses and extends food The mode of chain improves aquatic ecosystem, low cost, safeguards simple, can filter and precipitate pollutant.
The technical solution adopted in the present invention is:
A kind of method maintaining Landscape lake ecological balance, periodic detection algivorous insect and the density of submerged plant,
(1) if find algivorous insect throw in excess, when algivorous insect exceed normal value 50%, water surface area be 4000 square metres time, throw in The shrimp Seedling amount 0.8 ± 0.1kg of mussel amount 8 ± 1kg, 0.5-1.0cm/ of 4-5cm/, the snakeheaded fish 30 ± 4 of 50-150g/ tail Tail, tiger spot fish amount 15 ± 2 tail of 50-150g/ tail, when algivorous insect exceed normal value be other value, water surface area be other value time, Injected volume increases and decreases relative to above-mentioned injected volume equal proportion;
(2) if find submerged plant throw in excess, when submerged plant exceed normal value 50%, water surface area be 4000 square metres time, Throw in the Bellamya sp 5.5 ± 0.8kg of 300/kg, the Radix Raphani spiral shell 2.5 ± 0.4kg of 300/kg, when submerged plant exceedes normal value When being other value for other value, water surface area, injected volume increases and decreases relative to above-mentioned injected volume equal proportion;
Wherein, throw in the excessive measure taked for algivorous insect and throw between the measure that excess is taked for submerged plant It is independent of each other.
Further, throw in algivorous insect and submerged plant and be as the criterion the same day, carried out a Density Detection every ten days, altogether inspection Surveying three times, during detection, arrange several sample points in waters, the data obtaining each sample point are averaged, and then will Meansigma methods compares with normal value, extra proportion when whether being thrown in excess and throw in excess.
The invention has the beneficial effects as follows:
1. use the mode extending food chain to improve aquatic ecosystem, it is not necessary to life-time service electric power or medicine, two will not be produced Secondary pollution, low cost, safeguard simple;It is residual that the biology thrown in can prey on the water plant of substantial amounts of organic matter and corruption in substrate Bodies etc., are greatly lowered the content of organic matter and the release of nutrient substance in substrate, and meanwhile, the material of large-scale snail release is again water Flocculant natural in body, can reduce the suspended particle in water and adsorb substantial amounts of nitrogen and phosphorous nutrient, play filter and The effect of depositor;The biology thrown in, all in the growth stage, has vigorous demand of searching for food but will not produce original ecology Bigger destruction;After building perfect ecosystem, it is possible to realize the circulation of normal material and energy Flow function, water Middle nutrition Material can produce living resources, such as plant eggs such as all kinds of organic fishes, shrimp, spiral shell, shellfish animal proteinum and pasture and water after food chain converts White etc., a certain amount of economic output can be obtained by suitably fishing for.
2. the growth cycle of algivorous insect and submerged plant is one month (30 days) left and right, detects in three times, can be in difference Complete monitoring under growth conditions and safeguard.
Detailed description of the invention
A kind of method maintaining Landscape lake ecological balance, comprises the steps.
(1) it was as the criterion the same day with algivorous insect and submerged plant input, and carried out a Density Detection every ten days, detect three altogether Secondary, during detection, several sample points are set in waters, the data obtaining each sample point are averaged, then will be average Value compares with normal value, extra proportion when whether being thrown in excess and throw in excess.
The growth cycle of algivorous insect and submerged plant is one month (30 days) left and right, detects in three times, can be at not syngenesis Complete monitoring under long status and safeguard.
(2) if find algivorous insect throw in excess, when algivorous insect exceed normal value 50%, water surface area be 4000 square metres time, Throw in the shrimp Seedling amount 0.8 ± 0.1kg of 4-5cm/ mussel amount 8 ± 1kg, 0.5-1.0cm/ only, the snakeheaded fish 30 of 50-150g/ tail ± 4 tails, tiger spot fish amount 15 ± 2 tail of 50-150g/ tail, when algivorous insect exceed normal value be other value, water surface area be other value Time, injected volume increases and decreases relative to above-mentioned injected volume equal proportion;
(3) if find submerged plant throw in excess, when submerged plant exceed normal value 50%, water surface area be 4000 square metres time, Throw in the Bellamya sp 5.5 ± 0.8kg of 300/kg, the Radix Raphani spiral shell 2.5 ± 0.4kg of 300/kg, when submerged plant exceedes normal value When being other value for other value, water surface area, injected volume increases and decreases relative to above-mentioned injected volume equal proportion;
Wherein, throw in the excessive measure taked for algivorous insect and throw between the measure that excess is taked for submerged plant It is independent of each other.
Use the mode extending food chain to improve aquatic ecosystem, it is not necessary to life-time service electric power or medicine, will not produce Secondary pollution, low cost, safeguard simple;The biology thrown in can prey on substantial amounts of organic matter and the water plant of corruption in substrate Residuum etc., are greatly lowered the content of organic matter and the release of nutrient substance in substrate, and meanwhile, the material of large-scale snail release is again Flocculant natural in water body, can reduce the suspended particle in water and adsorb substantial amounts of nitrogen and phosphorous nutrient, playing filter Effect with depositor;The biology thrown in, all in the growth stage, has vigorous demand of searching for food but will not produce original ecology Raw bigger destruction;After building perfect ecosystem, it is possible to realize the circulation of normal material and energy Flow function, Shui Zhongying Support material and can produce living resources, such as plants such as all kinds of organic fishes, shrimp, spiral shell, shellfish animal proteinum and pasture and water after food chain converts Albumen etc., can obtain a certain amount of economic output by suitably fishing for.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted, And all these modifications and variations all should belong to the protection domain of claims of the present invention.
