Description

A kind of Habitat for Fish division methods based on hydrodynamic condition
Technical field
The invention belongs to fish management technical field, be specifically related to a kind of Habitat for Fish based on hydrodynamic condition and draw Divide method.
Background technology
Habitat is often referred to certain biological or region of certain ecological colony existence procreation or environmental form, broadly, dwells Breath ground concept not only contains the vivosphere of biology, also contains the whole envirment factors in vivosphere simultaneously.For For Fish, its habitat refers to maintain its orthobiosis, grows, looks for food, breeds and the place of other life cycles, Waters scope necessary to whole life cycle process is completed, such as spawning ground, feeding ground, wintering ground and connection difference including Fish The migration passage etc. in Life Stages waters, Habitat for Fish not only provides the vivosphere of Fish, also provides for meeting fish simultaneously Whole envirment factors that class is survived, grown, breeds, such as hydrodynamic force, hydrologic regime, quality of water environment, topography and geomorphology etc., hydrodynamic(al) Power, the hydrologic regime factor then lay particular emphasis on the HYDRODYNAMIC CHARACTERISTICS of Habitat for Fish, hydrologic process, and the quality of water environment factor then lays particular emphasis on The condition of water quality of Habitat for Fish, the topography and geomorphology factor lays particular emphasis on the physical aspect condition of Habitat for Fish.
Hydrodynamic condition is the extremely important envirment factor of Habitat for Fish, even part is all given birth in Fish life cycle The life stage is required to rely on certain specific hydrodynamic conditions just can live normally, grow, look for food, breed, as become Existence and the size of the Fish flow velocity to be leaned on of fluidity judge the swimming route even route of migration, and external fertilization Fish are in breeding During the region that current disorder degree is higher would generally be selected to carry out copulation, the most only reach certain disorderly journey at current Degree just can stimulate the generation of mating behavior, and may rest on the waters rest etc. of relatively placidity before and after laying eggs.According to water The difference of mechanics each characteristic quantity description object, can be divided into two types by the characteristic quantity characterizing river hydrodynamic condition:
The first kind is the index describing water movement feature, and representing the factor is flow velocity, Floyd's algorithm, Reynolds number.Flow velocity master What in habitat to be reflected, a certain section Fish laid eggs stimulates flow velocity, limit velocity and the degree at random in flow field.Floyd's algorithm Act on for fluid inertia force and the ratio of gravity, the main reflection habitat a certain section depth of water and the common of flow velocity, to judge current Torrent, the fluidised form situation of unhurried current.Reynolds number is the ratio of habitat a certain section fluid inertia force and viscous force, and Reynolds number is less Time, the impact of viscous force stream field is more than inertia force, and in flow field, flow velocity disturbance can decay because of viscous force, and fluid flowing is stable, for Laminar flow;Otherwise, if Reynolds number is bigger, the impact of inertia force stream field is more than viscous force, and fluid flowing is more unstable, flow velocity micro- Little change easily develops, strengthens, and forms turbulence flow flied disorderly, irregular.
Equations of The Second Kind is the index describing flow energy feature, and representing the factor is energy loss, kinetic energy gradient.Energy loss from Consume the reflection riverbed, the habitat habitat a certain section effect to water movement of water energy aspect, and fish locomotion is to be resisted Resistance situation.Kinetic energy gradient mainly reflects habitat a certain section current disorder degree, represents unit distance unit matter in current The kinetic energy change amount of amount, can quantify with distinguish the depth of water in river course, flow velocity is similar but water stream characteristics that environment position is different, it is possible to For estimating that Fish move to, from a certain position, the energy that another location is consumed.
The paddle construction of building, especially dam such as Hydraulic and Hydro-Power Engineering changes the water in river, place with running The envirment factor conditions such as power, hydrologic regime, quality of water environment, topography and geomorphology, to relating to the stock of fish in river and various Property creates profound influence.China has, as the whole world, the country that dam quantity is most, and dam quantity is still on continuous Rising, along with country's water conservancy and hydropower infrastructure construction dynamics of investment persistently strengthens in recent years, its quantity ascendant trend becomes apparent from, water The Habitat for Fish protection problem that the buildings of paddling such as diuretic electrical engineering bring is the most prominent, in the urgent need to planning and deployment section , reasonable, the Habitat for Fish protective measure of strong operability.At present, China's river fishes habitat protect, repair, compensate and Research work is greatly all in research, imagination, design phase, and reported correlational study is concentrated mainly on Habitat for Fish assessment Method scheduling theory research aspect, the research theory for the protection of river fishes habitat does not becomes system yet with technical system, is suitable for China river is actual and the technology maturation of national conditions, protected effect example preferable and convenient to operate, that implement more are a lack of, to engineering Actual guidance is limited, there is also gap, it is difficult to realize environmental benefit, warp compared with the most perfect theory and technical method Ji benefit, the most unified and balance of social benefit.
Summary of the invention
For solving the problems referred to above, the invention provides a kind of Habitat for Fish division methods based on hydrodynamic condition.? Under requirement based on river hydrodynamic condition, river fishes habitat is given subregion, classification, classification, and according to fish habitat Reparation, scheduling and the research work requirement on ground, plans, disposes and improves science, reasonable, the Habitat for Fish protection of strong operability Measure Systems, to realize the most unified and balance of environmental benefit, economic benefit, social benefit.
