Description
Technical field
The present invention relates to technical field of resource environments, more particularly to a kind of plant life suitable for river, lake restoration of the ecosystem field
Type ecology shoal construction method.
Background technology
Multifarious substrate topography and hydrodynamic condition are that river biology is dwelt the material impact factor of border condition, to biology
Structure of community and ecological process have violent influence.Under natural conditions, river waterpower moves the friendship for causing puddle and shoal
Mistake change, has also been correspondingly formed anxious, gradualization Complex Flow Status condition, has advantageously formed rich and varied river biota and fall.But
Under the conditions of Human impact, such as channelization, river cross-section unification, which are transformed, causes river puddle and shoal compound section condition
Lose, regime of river simplification, also resulting in the automatic recovery ability of river ecosystem reduces.Therefore, recover river course puddle and
Shoal staggeredly changes, and promotion forms multifarious fluidised form condition, recovers significant to river ecosystem health.
In river channel ecology environment remediation, structure and the recovery of aquatic vegetation are important steps.But on riverbed directly
Plant water plant is commonly encountered following problem：1. river bed deposit mud is thicker, root system of plant is difficult set, in addition high organic matter,
Black smelly bed mud condition is not easy to survive water plant；2. river course, because lock control draining etc. influences, water volume flow rate changes greatly, big stream
The flow condition of speed or high-frequency change in flow also easily make it that the water plant transplanted on bed-silt is destroyed by rush of water；3. in river course
The depth of water is deeper, and under water transparency low condition, hydrophyte restoration is difficult.
In addition, strengthened purification water quality of adopting an effective measure is also the key issue to be solved in river channel ecology environment remediation.
Also occur in practical application such as using the method for promoting water correction the methods of biofilm, filler, its method characteristic is single work(
Energy property, and need to realize by such as auxiliary equipment such as support, chinampa, reduce reliability.
The content of the invention
The present invention is directed to problem above, there is provided one kind can improve regime of river, promote hydrophyte restoration, fortified water
The construction method in the vegetation type ecological shoal of matter purification multifunctional.
