The present invention overcomes the deficiency that prior art exists, the removing of a kind of explosive harmful submerged plant that grows and the method for restoration of the ecosystem have been proposed, adopt free of contamination physical means to be removed to the harmful submerged plant that presents the outburst growth, thereby realize effectively thoroughly removing.
The present invention proposes removing and the ecological restoring method of a kind of harmful submerged plant of explosive growth, at first investigate harmful submerged plant growth area condition, formulate accordingly concrete removing and recovery scenario, and prepare various material requesteds.
The present invention includes following steps:
(1) harmful submerged plant is cradled processing, form the toothing of described harmful submerged plant.For example, the water caltrop group that presents the concentrated distribution that breaks out growth is cradled processing.Toothing is short as far as possible, and the height of toothing is below the 2cm.Plant after cradling is cleared out of water body.
Among the present invention, described harmful submerged plant refers to present the water caltrop group of the concentrated distribution that breaks out growth.Can also be other the harmful submerged plants with outburst growth characteristic.
(2) adopt overburden, described toothing is implemented to cover.
Among the present invention, described overburden is the shading Polypropylence Sheet.Preferably, described special overburden is thicker and toughness and light-proofness Polypropylence Sheet preferably, and its soffit is black (directly fitting tightly the toothing after contact cradles), and upper surface is the sandy soil look.
Wherein, the edge of described overburden arranges a hole every 1m at least, adopts fixed part by the hole described overburden to be fitted tightly and is fixed on the river bed.For example, overburden is fitted tightly by hole with spike and be fixed on the river bottom soiol surface.Preferably, but spike is to make with decomposing material (for example bamboo let).
Wherein, the time of described lasting covering is 2-5.
(3) after lasting the covering, during to described toothing place without harmful submerged plant growth of seedling and without seed survival, remove overburden, finish cleaning.For example, through the check, below overburden substantially without harmful submerged plant growth of seedling, without seed survival, then, overburden is withdrawn from, finish cleaning.
(4) plant and into suitable water plant kind or the kind of non-explosive growth the habitat of having removed described harmful submerged plant is repaired.This class water plant is the growth conditions that is fit to described habitat, remove the eutrophication ability strong and without harm, can comparatively fast form the excellent group of list of greater density, can occupy the ecological niche of harmful submerged plant of described explosive growth and water plant kind or the kind that stops it again to occupy.For example, water plant characteristics according to the region, place, selective adopt for removing the eutrophication ability strong and planted without the improved seeds of the black algae of damaging effect, eel grass etc., improved seeds have the advantages that growth is fast, density is large, in case form single excellent group, can stop the intrusion of harmful submerged plants such as water caltrop.
Among the present invention, the seed of not sprouting in the toothing after harmful submerged plant cradles and the seedling that has just sprouted and the soil can be choked to death because fitting tightly for a long time of overburden covers.Adopt this method substantially can reach the harmful submerged plant that presents the burst growth is carried out effectively ecological the removing and reparation.Pollution-free, the characteristics such as cost is low, instant effect, convenient, difficult recurrence that the inventive method has, ecological benefits and economic benefit are all good.
Description of drawings
Fig. 1 is the inventive method schematic diagram.
The specific embodiment
In conjunction with following specific embodiments and the drawings, the present invention is described in further detail, and protection content of the present invention is not limited to following examples.Under the spirit and scope that do not deviate from inventive concept, the variation that those skilled in the art can expect and advantage section are included in the present invention, and take appending claims as protection domain.Implement process of the present invention, condition, reagent, experimental technique etc., except the following content of mentioning specially, be universal knowledege and the common practise of this area, the present invention is not particularly limited content.
Embodiment:
Present embodiment illustrates with the inventive method the water caltrop group that park, somewhere artificial lake is the outburst growth is removed and restoration of the ecosystem step following (as shown in Figure 1):
1) investigates the water caltrop upgrowth situation spring, find that distributed more widely, many degree are large, population has outburst trend.
2) cradle processing.
Water caltrop is cradled, form the toothing of water caltrop, the height of toothing is below the 2cm.Water caltrop plant after cradling is cleared out of water body.
