Description
Technical field
The present invention relates to a kind of non inhabitation islands Intertidal zone stereo ecological restorative procedure, belongs to technical field of environmental management.
Background technology
Intertidal zone, refer to spring season highest water level and spring season lowest water level between seashore, that is, sea water rise to
During highest it is flooded where start the scope that surfaces when falling back on minimum to tidewater.The biology of tidal pool must have to be stood often
The ability of temperature difference per day and oxygen content acute variation, herein during the environment of cache the when of drying and it is high when humidity, temperature when low, salinity
It is constantly to change, the change of microenvironment is very big.
Non inhabitation islands have important ecological, economic, military and scientific research value, but region structure is simple, ring
Border relative closure, ecosystem composition are more single, and biodiversity index is little, and stability is poor, therefore is one more relative
Fragile geomorphic unit.Used as the important component part of island ecosystem, Intertidal zone substrate, geomorphic type are various, hydrology shape
Condition is intricate, with the bio-diversity compared with horn of plenty, wherein widely distributed a large amount of miscellaneous tangleweeds.Sea jungle
Not only there is very high primary productivity, be the starting point of whole marine food chain：And offshore Carbon cycle process is also played non-
Often important effect, is the important component part of biogeochemical cycle in ocean.
With appearance the problems such as environmental pollution and nervous man-land relationship, the natural environment and ecosystem on island are subject to
Great threat and destruction, especially Intertidal Algae field.Intertidal zone tangleweed is without image of Buddha other biological by cruising
Mode hides extraneous unfavorable factor, and the good and bad direct blocks of environment have determined the breeding of Sargassum and raw land, cause many islands island beach,
The dense zhang type Sargassum of island base (surely raw algae) is degenerated or desertification, and bio-diversity is reduced, and then is made with Sargassum as basic bait
Bottom dwell (Intertidal zone)
Ecosystem and littoral ecosystem be subject to it is very big destroy, therefore, the breeding of tangleweed and growing state can be more
Directly reaction surrounding enviroment quality, is preferable environmental indicator.The biological restoration of non inhabitation islands sea jungle, for whole
Island ecosystem functional rehabilitation simultaneously reaches self―sustaining tool significance.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of non inhabitation islands Intertidal zone stereo ecological is repaiied
Compound recipe method.
The technical solution adopted for the present invention to solve the technical problems is：
Non inhabitation islands Intertidal zone stereo ecological restorative procedure, the restorative procedure comprise the steps：
（1）Sustained-release activity nutrient pack is filled：After ebb, some sustained-release activity nutrient pack are spacedly distributed and are filled in Intertidal zone
In, spacing distance is 1-1.5m, and landfill depth is 20-30cm, and, by yeast fermented waste fluid, addition is suitable for the sustained-release activity nutrient pack
The waste liquid and magnetic ordered mesoporous carbon of amount alkalinity extraction glucosan, Jing flocculations, sedimentation, dry and degradation material parcel are obtained；
（2）The field planting of short Zostera marina：The short Zostera marina for pipetting healthy growth is colonized in the periphery of sustained-release activity nutrient pack, with slow release
Active nutritional inter-packet gap distance is 0.2-0.3m, and the spacing between short Zostera marina is 0.1-0.15m, and field planting depth is 10-15cm；
（3）Sargassum thunbergii seedling is sowed：Ready sargassum thunbergii germling is splashed in the region of landfill sustained-release activity nutrient pack,
Sow 2-3 time repeatedly, increase germling density, spread 1 time at interval of the opportunity after-culture that a week chooses after ebb, continue at least 4 weeks.
Preferably, the preparation method of the sustained-release activity nutrient pack is specific as follows：Yeast fermented waste fluid and alkalinity extraction Portugal
The waste liquid of polysaccharide 5-8 by volume:1 ratio mixing, the magnetic for being subsequently adding waste liquid cumulative volume 1-1.2% mass are order mesoporous
Charcoal, then stirs, and is placed in natural flocculation sedimentation 24-32h in Sedimentation tank, collects bottom solid content, and Jing is dried, crushing is obtained
Sustained-release activity nutritive powder, obtains sustained-release activity nutrient pack, single sustained-release activity nutrition via degradable leatheroid or non-woven wraps
The quality of bag is 0.8-1.5kg.
Preferably, the preparation method of the sustained-release activity nutrient pack is specific as follows：Yeast fermented waste fluid and alkalinity extraction Portugal
The waste liquid of polysaccharide by volume 6:1 ratio mixing, is subsequently adding the magnetic ordered mesoporous carbon of 1.2% mass of waste liquid cumulative volume, so
After stir, be placed in Sedimentation tank natural flocculation sedimentation 30h, collect bottom solid content, Jing dries, crushes and obtain sustained-release activity
Nutritive powder, obtains sustained-release activity nutrient pack, the quality of single sustained-release activity nutrient pack via degradable leatheroid or non-woven wraps
For 1.2kg.
Preferably, the yeast fermented waste fluid is bakery yeast fermented waste fluid.
The present invention is rich in the trace element of natural Organic substance and adsorption storage by sustained-release activity nutrient pack, fills in tide
Between in band in, washed away and natural diffuseness by tidewater, continue slow release degraded, can greatly avoid the loss of nutrient,
It is that short Zostera marina and sargassum thunbergii growth provide lasting nutrition supply, short Zostera marina and sargassum thunbergii propagation growth are fast, improve between tide
Band ecological environment.
Remain substantial amounts of active yeast, nitrogen, phosphorus, potassium, magnesium elements in yeast fermented waste fluid, and cell is secreted to extracellular
Reactive intermediate, fermented waste fluid is typically in faintly acid；In alkalinity extraction glucosan, the glucosan residue rich in macromolecule, has
Absorption and the effect flocculated, in alkalescence；Magnetic ordered mesoporous carbon has huge specific surface area and abundant three dimensional pore structures,
High-specific surface area is conducive to the adsorption storage of active component, and regular orderly open duct, the aperture of size adjustable are activity
The natural diffuseness of composition provides path, is conducive to the long-time of active component slowly persistently to produce.Yeast is fermented by glucosan
Effective ingredient Jing absorption and flocculation in waste liquid（Bridge formation function）, Accelerated subsidence, magnetic ordered mesoporous carbon can adsorb micro unit
Element and small molecule are difficult to the active component for flocculating and settling, and it is nutritious rich that three is mixed with the sustained-release activity nutrient pack for obtaining
Richness, easy to use, had good sustained release effect.
It is furthermore preferred that the yeast fermented waste fluid is bakery yeast fermented waste fluid.Rich in remaining paddy Guang in bakery yeast
Sweet peptide, finds in practice to short Zostera marina and sargassum thunbergii growth and breeds with significant facilitation.
The invention has the beneficial effects as follows：The present invention is rich in natural Organic substance and adsorption storage by sustained-release activity nutrient pack
Trace element, in filling in Intertidal zone, washed away and natural diffuseness by tidewater, continued slow release degraded, Ke Yiji
The big loss for avoiding nutrient, is that short Zostera marina and sargassum thunbergii growth provide lasting nutrition supply, short Zostera marina and sargassum thunbergii
Propagation growth is fast, improves intertidal zone environment.
