Description
Technical field
The invention belongs to egg-laying season pulse flow studying technological domain, it is related to a kind of fish egg-laying season ecological water demand of rivers mistake
The computational methods of journey.
Background technology
The pulsed change procedure of runoff is that plant, microorganism, invertebrate and the fish life of river and wetland are followed
The main drive of ring.It is continuous that biological substance and the Flow characteristics of abitotic substance occur for the change of water level and discharge process
Change, constantly changes the ecological ring of the diversification such as river course, turnout, tributary and delta, shoal, torrent, pool and water purification region
The flow condition and material conditions in border, the composition and diversity of the distributions of species, abundance and aquatic animals and plants group, meanwhile,
Main stem and the forfeiture of beach cross connection can cause population isolate and fish and other biological extirpation.Example
Such as, the migration spawning of fish has a direct relation with the flushing process of flow and the size of flow, and the growth of beach vegetation and
Abundance is closely related with the change of flood frequency and flood level.
The material between the adjacent systems such as between river system and same land, lake, ocean in River Hydrology process control
Exchange, energy exchange and biology are exchanged.In the dry season, current are existed only in the range of limited main stem, river system and
Floodplain is separate, and aquatile activity is in the range of less waters.And in abundance of water season, water level goes up, flow velocity
Increase, now aquatile growth is rapid, and part fish are stimulated by current starts the migration in river course.When flow pulse persistently increases
Plus, water surface area further expands, and flow velocity is reached to a certain degree, and part fish start spawning in suitable habitat condition.When
Water level crosses flood land line water level, and current constantly pour into floodplain by river, and river is connected as a single entity as unified dynamic water with Tan Qu
Region.Major trough water body also provides energy and organic nutrient substance input during being overflowed to beach area for floodplain, while beach area
Also it is released by the nutriment flooded in soil, gradually forms complete river ecosystem.When major trough flow reaches peak value
When, waters scope reaches maximum, and the living environment of aquatile and terrestrial organism suffers from violent interference, forces biology to be migrated
Or adaptive change is produced to flood.The water level increase period is the peak period of fish procreation, and the peak of planktonic organism procreation is then
Before the phase of rising terminates.As can be seen here, the pulsed change of discharge of river is that river biota falls to change topmost control
The factor, the transverse hydraulic contact in river and Cycle of nutrients, are provided more rich for biological habitat and food web frame
Selection, breeding to aquatile and growth have critical effect.
, will according to the size of flow and the frequency occurred with reference to flow pulse process to fish migration and the influence of spawning
Traffic partition is low discharge, high impulse flow, small flood, four kinds of feature flows of great flood.Wherein, low discharge is used as river course base flow
Amount, maintains streamflow condition, provides living space in freezeup period for biology, discharge process below low discharge, can hinder for a long time
Hinder river vertical communication and cross connection, and the vital movement of part aquatic organism is caused to suppress.High impulse flow refers generally to
Flow rises to more than low discharge, but not higher than bank-flush discharge.High impulse flow is the main stimulation of fish migration and spawning, is also
Mould the key factor of bed configuration and substrate condition.Meanwhile, caused by high flow capacity pulse can be alleviated under low flow condition
Water environment pressure.Small flood refers to water level and exceedes bank-flush discharge more than main stem riverbank, i.e. flow, and the general return period is 2-10
Year, the hydraulic connection between river transverse direction can be strengthened, more rich habitat condition is provided for aquatile.Frequency occurs for great flood
Rate is relatively low, and the return period is generally greater than 10 years, but it has played indispensable effect in river ecosystem.Great flood prolongs
Long flood plain flooding time, maintains the diversity of animals and plants species, spawning ground can also be effectively washed away, by large amount of organic matter
Downstream is poured, and makes the water quality of main stem and flood plain water body more preferable.Ecology Action such as table 1 of each flow component to fish
It is shown.
Ecological significance of the different flow component of table 1 to fish
It is high in all ecological flow elements based on the biological significance of each flow key element in flood pulse concept
Flow pulse process is to stimulate fish migration and lay eggs and maintain habitat and provide the key element in fish food source,

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and examples
The present invention is further elaborated.
A kind of computational methods of fish egg-laying season ecological water demand of rivers process, comprise the following steps：
1. 4-5 months, suitable pulse flow was adjusted
1.1 habitat suitability curves
In Songhua River Basin, migratory cold water fish is feature species, due to some large-scale water conservancies in mainstream and Navigation ＆ Hydropower Junction Engineering
Build, the species such as most representational dog salmon, taimen have been disappeared, and generally acknowledged regional water is difficult to find that in existing fish
Ecosystem indicator species.Secondly, Songhua River Basin fish spawning has clear and definite seasonal variation, and different fish egg-laying times have
Very big difference, if only considering the spawning demand of a certain or several fish, pole will be caused for the fish that this non-period lays eggs
Big influence, so as to also influence the stability of whole Songhua River Basin aquatic ecosystem structure.3rd, the fish of same Type of Spawning
It is basically identical, such as adhesive egg fish for the hydrodynamic condition demand after the selection for habitat of suitably laying eggs, and spawning
Class is needed in the spawning of shallow water area of slack water so that fish-egg can be attached on offshore pasture and water, on cobble, Drifting egg fish then it is preferably
Laid eggs in torrent, while also needing to maintain certain flow velocity after spawning, ensure the floating of fish-egg.Therefore, object of the invention
It not is to be directed to a certain or several fish to plant, but by the classification to the whole fish egg-laying times of Songhua River Basin, each
Individual spawning period, according to fish Type of Spawning, sets up the habitat suitability song of production adhesive egg fish, Drifting egg fish respectively
Line, curvilinear correlation parameter is at utmost to meet the integration requirement of category fish as principle.Due to production demersal egg fish habitat
Ground suitability degree key factor is river course substrate situation, and produces buoyant egg fish for spawning ground hydrodynamic conditions requirement relatively
It is low, therefore do not studied individually.
The fish overwhelming majority that Songhua River Basin 4-5 months lay eggs is adhesive egg, be attached to after adhesive egg spawning pasture and water,
On cobble, generally produce in shallow water area of slack water, the overbank of large area is needed for spawning ground.It is glutinous according to 42 kinds of productions of Songhua River Basin
Property ovum fish comprehensive analysis, its suitable depth of water of maximum spawning is no more than 1m, therefore 1m is suitable as the adhesive egg fish depth of water
Write music the maximum of line, 0.1m is the suitable depth of water as the minimum depth for meeting fish spawning, 0.4-0.8m, obtains Song Hua River stream
Domain production adhesive egg fish egg-laying season depth of water suitability degree curve is as shown in Figure 1.And need to be attached to pasture and water, cobble after adhesive egg output
Upper hatching is, it is necessary to which certain current keep water quality and nutrients conveying, but flow velocity is unsuitable excessive, therefore by 0.1m/s-0.2m/s
As the suitable flow rate of adhesive egg fish egg-laying season habitat, 0.5m/s is limit velocity, obtains Songhua River Basin production adhesive egg
Fish egg-laying season flow velocity suitability degree curve is as shown in Figure 2.
1.2 egg-laying season appropriate flow rates
In 26 sections with important ecological significance, 6 sections are had, totally 9 plasm resource protection areas are distributed in
On the big mainstream in Song Hua River three, its distributing position is as shown in Figure 3.Wherein 2, Nenjiang mainstream plasm resource protection area is distributed in river
Bridge is to great Lai sections, the benchmark section adjusted using the big grant station of Nenjiang Outlet Section as the section pulse flow；Second Songhua River 1
Individual plasm resource protection area is distributed in Song Hua River downstream Songyuan City section, and the section pulse flow is used as using two loose Outlet Section Fuyu County stations
The benchmark section of accounting；There are 4 to be distributed in junctions to Harbin section in 6 plasm resource protection areas of main stream of Songhua River, thus it is loose
The benchmark section that Hua Jiang mainstreams are adjusted using Shunting Yard of Harbin Marshalling Station as the section pulse flow.In view of the actual schedule of hydraulic engineering
In, the discharge process of Shunting Yard of Harbin Marshalling Station has determined loose downstream lily magnolia, the discharge process of Jiamusi section substantially, therefore for
The ecological section of emphasis of loose downstream lily magnolia section, Jiamusi section, no longer individually carries out the accounting of pulse flow.
The habitat suitability curve that upper section is set up imports PHABSIM models, with 50m3/ s flow intervals difference mould
Intend Dai Ji-Harbin section fish under the conditions of flow is incremented by under two loose stream Songyuan City sections, the big grant section in Nenjiang mainstream and main stream of Songhua River
The class egg-laying season effectively perches ground area (WUA) change, obtains the variation relation song that ground area and flow are effectively perched in 3 sections
Line, as a result as shown in Figures 3 to 5.
For Second Songhua River, when Fuyu County station flow is 550m3During/s, Songyuan City Song Hua River Yin Xenocypris national level aquatic products germplasm moneys
Effective ground area of perching of section adhesive egg fish where source protection area is maximum, close to 50hm2/ km, to reach that maximum can use is dwelt
The 80% of ground area is ceased as pulse flow span, then pulse flow lower limit of the Second Songhua River downstream in 4-5 months
460m should be not less than3/ s, and peak value is preferably not higher than 680m3/s。
For Nenjiang mainstream, when big grant station flow is 450m3During/s, the big peace section ussuriensis in Jilin Province Nenjiang, Nenjiang
Effective ground area of perching of section adhesive egg fish where the national Fish Germplasm Resources protection zone of Zhenlai section 2 is maximum, is
42hm2/ km, to reach that maximum can use perch ground area 80% as pulse flow span, then Lower Nenjiang is in the 4-5 months
The pulse flow lower limit of part should be not less than 340m3/ s, and peak value is preferably not higher than 500m3/s。
For main stream of Songhua River, when Shunting Yard of Harbin Marshalling Station flow is 950m3During/s, preserved egg Jiangning river section, Song Hua River Zhaoyuan section flower
Section adhesive egg where fish-bone, Song Hua River Shuangcheng section Gui Yin Xenocypris, the national Fish Germplasm Resources protection zone of Song Hua River Zhaodong section 4
Effective ground area of perching of fish is maximum, is 51hm2/ km, maximum available perch the 80% of ground area and is used as stream of pulses to reach
Span is measured, then pulse flow lower limit of the loose Harbin section in 4-5 months should be not less than 810m3/ s, and peak value is best
Not higher than 1070m3/s。
2. 6-7 months, suitable pulse flow was adjusted
2.1 habitat suitability curves
In the 68 kinds of fish laid eggs in Songhua River Basin 6-7 months, the Type of Spawning of 57 kinds of fish is collected into altogether, wherein 28 kinds
Fish produce adhesive egg, and 15 kinds of fish produce Drifting eggs, 5 kinds of production buoyant eggs, 4 kinds of production demersal eggs, are laid eggs in 4 in the freshwater mussel gill.It can be seen that
In the egg-laying season in 6-7 months, in addition to the suitable enviromental conditions for spawning of adhesive egg fish to be considered, emphasis is also wanted to consider production Drifting egg
Suitable spawning ground and fish-egg drift about needed for hydrodynamic condition.
The fish of production drift fish-egg generally have the characteristic of abortive egg, and the accommodation for the depth of water is wider, and
There is higher requirement for flow velocity.The depth of water scope that such as silver-colored silver xenocypris is distributed in the egg-laying season is 20cm to 2.3m, and flow velocity typically exists
0.6-1.1m/s；The depth of water scope being distributed like bream in the egg-laying season is 60cm to 2-3m, flow velocity typically in more than 0.3m/s.By right
The comprehensive consideration of Drifting egg fish is produced, the suitable depth of water for producing Drifting egg fish 6-7 months is defined as 1m-2m, minimum is faced
Boundary's depth of water is 0.2m, and maximum critical depth of water is 3m；Suitable flow rate is defined as 0.6-1.2m/s, ensures that fish-egg floating is not sunk to the bottom most
Small critical flow velocity is 0.2m/s, it is considered to which fish trace back ability, and maximum critical flow velocity is set into 2m/s.Obtain Songhua River Basin production drift
The depth of water of fluidity ovum fish, flow velocity suitability degree curve are as shown in Figure 6 and Figure 7.
2.2 egg-laying season appropriate flow rates
The habitat suitability curve that upper section is set up imports PHABSIM models, equally with 50m3/ s flow intervals point
Dai Ji-Harbin section condition Mo Ni not be incremented by flow under two loose stream Songyuan City sections, the big grant section in Nenjiang mainstream and main stream of Songhua River
The lower fish egg-laying season will effectively perch ground area (WUA) change, obtain 3 sections and produce Drifting egg fish in 6-7 months effectively dwelling
The variation relation curve of ground area and flow is ceased, as a result as shown in Fig. 8 to 6-10.
From figure 8, it is seen that with the increase of Second Songhua River flow, is produced from the suitable spawning grounds of Drifting egg fish also not
Disconnected increase, but when Fuyu County station flow is more than 700m3After/s, advancing the speed for spawning ground area significantly diminishes, corresponding drift
Ovum fish effectively perch ground area about 44hm2/km.In view of 6-7 months except production Drifting egg fish, also substantial amounts of production
The habitat of adhesive egg fish needs also exist for protection, to produce effectively perching ground area and reach 40hm for adhesive egg fish2/km
(the 80% of optimum level), Fuyu County station range of flow should be 460-680m3/ s, in this flow rate zone, produces Drifting egg fish
Ground area is effectively perched with flow to rise and dramatically increase.Therefore, section production adhesive egg and Drifting egg fish are considered
