Description

A kind of Multifunctional suspension floating river ecological enclosure experimental facilities
Technical field
The utility model relates to water conservancy experimental technique field, specifically a kind of Multifunctional suspension floating river ecological enclosure experimental facilities.
Background technology
Because body eutrophication or other reasons, cause algal bloom in the short period, wawter bloom (in the fresh water) or red tide (in the seawater) phenomenon have namely occured, subsequently these algae meeting mortalities, cause the decline of Dissolved Oxygen in Water concentration, fish kills, water body stench, cause adverse effect for water quality, aquatic border and water landscape.From between the seventies in last century till now 40 years, national lake eutrophication Area Growth about 60 times, now reached about 8700km 2, and eutrophic water is shifting to some natural lakes, river.As seen, eutrophication problem is just becoming day by day serious.
At present wawter bloom mainly occurs in the lower waters of lake uniform flow, and natural river is because flow velocity is very fast, very strong self-purification capacity is arranged and wawter bloom seldom occurs, but be under the special state when the river, also wawter bloom can occur.And there is significant difference in river type wawter bloom with the lake type wawter bloom aspect a lot, such as river flow change obviously, river water temperature, nutriment concentration circulating are very fast etc., these factors are larger to river course type wawter bloom process influence.To achievement in research and the understanding of river type wawter bloom, the factor that affects the wawter bloom process can be summarized as based at present: flow rate of water flow, nutriment concentration, water temperature, intensity of illumination etc. under water.
The structure very complex of aquatic ecosystem, actual river ecological process coverage is wide, longer duration, actual ecology observation is also very difficult, because the complexity of the restriction of laboratory condition, sampling sample change of water quality and algae growth mechanism, laboratory experiment has significant limitation, and the experiment of the enclosure of field condition can keep the water body reset condition, also can artificially control the wawter bloom occurrence condition, therefore be used widely.A kind of preferably means that the at present ecological enclosure experiment of field condition is research wawter bloom problem, ecological enclosure is the microcosmYou Chengweiyuzhou that a kind of artificial design commonly used in the ecology forms, the purpose of this method is to set up the model ecosystems of a complexity, and the ecosystem under the energy simulating natural environment also reaches certain accuracy.The enclosure experiment has a variety of, is divided into 3 classes according to the large I of volume: small scale enclosure (Microcosm, 1～10m 3), mesoscale enclosure (Mesocosm, 10～100m 3), large scale enclosure (Macrocosm,＞100m 3), also have other several classification, generally, as long as flexible and suitable application, just can obtain farthest understanding to local river ecosystem by ecological enclosure experiment.
Being designed with of reported ecological enclosure experimental facilities is a variety of, but all has certain defective at the aspects such as fastness of design cost, experiment specific aim, device, and is the research that is applied to the fields such as marine red tide or fishery cultivating mostly; In addition, the expense bulky, assembly of most ecological enclosure device is higher, assembling is loaded down with trivial details, reaches universal certain difficulty of having brought for the enforcement of field condition enclosure experiment; In addition, the project that most ecological enclosure devices once can be tested is less, i.e. the factor that research affect the wawter bloom genesis mechanism seldom can not be carried out the comparative analysis of wawter bloom differentiation under the multifactor functioning well.
