Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1, a kind of restorative procedure of degeneration mangrove of the invention, comprising:
1) land mangrove on-site investigation determines and repairs area；
2) area is repaired in isolation；
3) moisturizing facility is built, to reparation area's moisturizing；
4) area's water table management is repaired；
5) repairing effect is evaluated.
Land mangrove on-site investigation: on-site investigation mainly investigates landform situation including the use of unmanned plane and water body is distributed,
Substrate physicochemical property and structure of community investigation and plant health condition evaluation.For mangrove health shape caused by land
Condition degenerate problem takes make-up water measure to carry out reparation and child care.
Area is repaired in isolation: according to on-site investigation as a result, selection restoring area, by the way of enclosing and building earth embankment, isolation is repaired
Area, on the one hand for preventing the seawater introduced outflow, on the other hand for marking restoring area.Earth embankment section is trapezoidal, bottom
Wide 60cm, top width 30cm, height 25cm.
It builds moisturizing facility: being distributed according to the landform situation of unmanned plane investigation and surrounding body, design applicable pumping plant system
System and transportation system.Pumping station system mainly considers that operation power, operating voltage and water outlet aperture, the water body of drainage are Natural Water
Body, i.e. seawater, depth of water 2m or more, and avoid pollution sources.Transportation system mainly considers water band material, bore, length and laying side
Formula, water transport port, which is located at, repairs district center.
It repairs area's water table management: with minimum, the effect most preferably principle that consumes energy, being tested through multiple moisturizing, by monitoring water level
And response of the mangrove to SEA LEVEL VARIATION, optimize moisturizing water level and period.By verifying, suitable beginning moisturizing water level :-
10cm ± 2cm terminates moisturizing water level: 0-2cm, and according to Various Seasonal precipitation event, divides the seasonal adjustment moisturizing frequency.
Repairing effect evaluation: by with do not repair area's (control group) or repair the modes such as comparison of front and back, evaluate substrate
The improvement situation of physicochemical property and plant health situation.Substrate physicochemical property mainly includes moisture content, salinity, total nitrogen and organic matter
Content.Plant health status index mainly includes tree vigor, chlorophyll content, Photosynthesis fluorescent parameters and photosynthetic parameters；
Wherein, tree vigor reflection overall growth is horizontal；Photosynthesis fluorescent parameters include II maximum fluorescence efficiency (Fv/Fm) of PS, II reality of PS
Border Photochemical Efficiency (Φ PS II) and photochemical quenching coefficient (qP), mainly reflect optical energy utilization efficiency；Photosynthetic parameters master
It to include Net Photosynthetic Rate, inter-cellular CO2 rate and water use efficiency.
Embodiment:
Below with reference to the embodiment that is configured to of a demonstration area, the present invention will be described in detail, which is Shenzhen Qiao Cheng wetland
Degeneration mangrove repairs Demonstration Base.
S01 investigates land mangrove status.Using Shenzhen Qiao Cheng wetlands degradation mangrove as research object, history money is collected
Material carries out sample-plot survey.Landform situation and water body distribution and background survey, structure of community tune are investigated including the use of unmanned plane
Plant health evaluating before looking into and repairing.
S02 is determined and is repaired target and measure.Field investigation and evaluation result show that emigrant city wetland mangrove exists and ask as follows
Topic: the phenomenon that siltation is serious, shows " mangrove terrestrial " affects the normal growth of mangrove (especially autumn eggplant) and numerous
It grows, standing forest is increasingly degenerated.To solve the above problems, taking make-up water measure, wetland water level is adjusted, carries out and repairs and child care demonstration work
Make.
S03, reparation separate from.The autumn eggplant woods (dominant tree) in land is selected to repair object.Further to verify
The validity of moisturizing restorative procedure, in autumn eggplant woods with designing 2 pieces of samples, respectively moisturizing processing group (30*10m2) and control group
(30*10m2)；Further, 3 sample prescriptions are further subdivided into various kinds.In sample ground, the design wide 60cm in bottom, top width 30cm,
The isolation earth dyke of height 25cm, for preventing the seawater introduced outflow and label autumn eggplant woods from repairing demonstration area.
S04, moisturizing facility are built.In conjunction with sample landform and surrounding body details, in Chinese Overseas Town, dock constructs pumping plant
System, power: 4Kw；Voltage: 380V；Water outlet internal diameter: 5cm.By transportation system, that is, be about 300m water band (internal diameter:
5cm), the seawater of Chinese Overseas Town wetland natural water is periodically transported in autumn eggplant woods, to restore the periodical water logging of autumn eggplant woods
Habitat.Water transport port position in sample center.Drainage point selection comprehensively considers water quality, water, route planning and cost factor, need to keep away
Sewage draining exit is opened, prevents from introducing pollutant, maintains 2m with headwater depth, guarantees to supply water sufficient, landline planning fully considers maintenance
Convenience and cost factor.
S05, water table management.With minimum, the effect most preferably principle that consumes energy, tested through multiple moisturizing, by monitoring water level with
And autumn eggplant woods optimizes moisturizing water level and period to the physiological responses of SEA LEVEL VARIATION.Suitable beginning moisturizing water level: -10cm ±
2cm terminates moisturizing water level: 0-2cm.The optimal water complementation of the present embodiment are as follows: each moisturizing 6 hours, to flood bed mud surface 1cm
For standard.Water level can be reduced to original level after moisturizing 4 hours (lower than bed mud surface 5cm).The moisturizing frequency is with season tune
It is whole, specifically: (1) rainy season: per half a month moisturizing is primary, each moisturizing 6 hours.(2) dry season: moisturizing is primary weekly, and 6 is small every time
When.
S06, repairing effect evaluation.Mainly in terms of bed mud physicochemical property and autumn eggplant woods health status improve two, use
With the direct way of contrast of control group, the repairing effect of make-up water measure is verified.The result shows that: it is aqueous that moisturizing processing improves bed mud
Rate, average salinity, total nitrogen and the content of organic matter, improve the nutritional condition (as shown in Figure 2) of deposit.Compared with the control group,
After moisturizing is handled, the branches and leaves growing way of autumn eggplant storey is luxuriant, and deadwood is less, and the autumn eggplant storey deadwood of control group is more,
Blade phenomenon of withering and falling is obvious；Moisturizing group occurs new branch on 2m high trunk below and sprouts, and this phenomenon is in control group
In do not occur；Moisturizing remarkably promotes Kandelia candel leaf growth (as shown in Figure 3), meanwhile, chlorophyll a synthesizes (as shown in Figure 4), light
Energy utilization rate (as shown in Figure 5), Net Photosynthetic Rate and water use efficiency (as shown in Figure 6) significantly improve, assimilation enhancing.
Simply to illustrate that technical concepts and features of the invention, its purpose is allows in the art above-described embodiment
Those of ordinary skill cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all
It is the equivalent changes or modifications that the essence of content according to the present invention is made, should be covered by the scope of protection of the present invention.
