Description
Technical field
The present invention relates to a kind of ecological riverway and administering method, belongs to river regulation technical field.
Background technology
Meander stream is the result of river itself river bed change.During river overbending, river body is cranky to leading off
Flood is unfavorable, easily triggers flood.It is generally believed that to these meander streams implement cut-off can effectively lower cut it is curved
Section upstream flood position simultaneously improve the flood control capacity of upstream, however, it is this to natural river it is artificial reconstructed for the mankind bring it is huge
While interests, inestimable destruction inevitably also is caused to the ecological environment in river.Due to original tortuous channel
Destroyed or abandonment, the habitat diversification of straight cutoff is relatively low with complexity, causes the aquatile biology in river more
Sample declines；On the other hand, since river water is shorter in straight cutoff residence time, and the aquatic ecosystem knot of cutoff
Structure is single uncoordinated, and the self-purification capacity in river declines, and causes the water pollution problems of downstream river course to be aggravated.
Although currently the pollution problem and Ecology problem for river have formd more effective water pollution
Administer and aquatic ecosystem constructing technology system, but these river regulation technologies coordinate river flood passage water drainage,
The function such as purification of water quality and bio-diversity conservation.

The emergent aquactic plant is one kind in canna, reed, typha angustifolia, and the submerged plant planted in deep water pool is
Eel grass or hydrilla verticillata.
The curved type of girt, cutoff are of a straight line type.
Based on a kind of ecological riverway administering method, comprise the following steps：
1. choose girt：By satellite map and reconnaissance trip, girt is chosen；
2. determine river ring starting point and river ring terminal：The topography and geomorphology of girt is 1. obtained according to step, determines girt
River ring starting point and river ring terminal；
3. excavated：Region between river ring starting point and river ring terminal is excavated, forms a cutoff, the Xinhe River
Road is made of river entrance, river Drainage Section and river outlet, and the river entrance of cutoff is connected with river ring starting point, river entrance
Bifurcation mouth is formed with girt, the river drainage end of cutoff and girt are separate, river outlet and the river ring of cutoff
Terminal connects；
4. deep water pool is set：Deep water pool is excavated in the middle of the river of cutoff, and planting submerged plant is planted in deep water pool, deep water pool
Surrounding plantation emergent aquactic plant；
5. cutoff gate and girt gate are set：In the bifurcated mouth of girt and cutoff, Xinhe River banister is set respectively
Door and girt gate；
6. aquatic ecosystem reparation is carried out to girt：Several are set to repair unit in girt, in each reparation
Planting submerged plant is planted between unit.
The step 3. in, cutoff is straight river.
The width of the cutoff is wider than the width of girt.
The beneficial effects of the present invention are：
1. remaining girt after river transformation of cut-offfing, upland water can be carried out by the control of 2 gates
Allocate by stages, cutoff gate is opened in flood period can efficiently solve flood passage water drainage problem；
2. in non-flood season, upland water is mainly passed through girt, maintain that river is original to inhabit habitat and water body
Self-purification capacity；
3. by carrying out aquatic ecosystem reparation or structure in new girt, the water body self-purification ability in river is enhanced, is carried
These river habitat suitabilities have been risen, precondition has been created for purification of water quality and bio-diversity conservation, properly handles
