Abstract
A kind of method of fast quick-recovery degeneration reed wetland, is related to a kind of restoration methods of degeneration reed wetland.Input cost the present invention is to solve degraded wetland reed restoration methods is higher, recovers slow, is difficult to promote and the single problem of restoration methods.Method：First, the reed wetland degenerated in selection reed wetland is used as recovery region；2nd, the dry branches and fallen leaves for recovering region earth's surface is removed, pretreated reed wetland is obtained and is recovered region；3rd, in 3 April, the topsoil that pretreated reed wetland recovers region is excavated, is elapsed topsoil in the horizontal direction using bull-dozer, and the soil for coming will be boosted and pile discontinuous trapezoidal mesa-shaped mound.In recovery district more than 85% degraded wetland can be just set to be restored then using this method, and recovery district spring reed germinating time at least shifts to an earlier date 10 15 days, reed height ring improves more than 30% than improving 30 40cm, biomass.The present invention is for recovering degeneration reed wetland.
Description
Technical field
The present invention relates to a kind of restoration methods of degeneration reed wetland.
Background technology
Reed belongs to herbaceos perennial for grass family reed, has the sturdy rhizome crawled, and has seminal propagation and plant division numerous
Grow two kinds of modess of reproduction.The plant of reed is tall and big, and stalk is high up to 3m, and footpath has 20 more pieces up to 4cm；Blade is flat, and length is reachable
45cm, it is wide up to 3.5cm；It is born in rivers lakes and marshes, the edge zone of pond irrigation canals and ditches more, is widely distributed in northern China wetland.
Reed wetland checking winds and fixing drifting sand, maintain bio-diversity, regulate the climate, purify water, the aspect such as improved soil has
There are important ecological functions, due to climate change and the influence of irrational utilization mode, many reed wetlands all suffer from area
The situations such as atrophy, deterioration.
It is many at present to be recovered or rebuild using restoration methods such as seedling cuttage, ecological water supplements for reed wetland, although
The stability of community that these aspects can be played after certain recovery effects, but recovery or reconstruction is poor, and Resuming agent is also higher, and
For the reed wetland that large area is degenerated, currently except using measures such as hydrology regulation and control, lacking with low cost simple and feasible always
Restoration methods.
The content of the invention
Input cost the present invention is to solve degraded wetland reed restoration methods is higher, recover slow, be difficult to promote with
And the single problem of restoration methods, there is provided a kind of method of fast quick-recovery degeneration reed wetland.
The method of fast quick-recovery degeneration reed wetland of the invention, is carried out according to the following steps：
First, there is the reed wetland of significant degradation trend as recovery region in selection reed wetland；
2nd, the dry branches and fallen leaves for recovering region earth's surface is removed, pretreated reed wetland is obtained and is recovered region；
3rd, do not thawed completely in spring Wetlands In Northeast China soil, and before reed does not germinate also (3-4 months),
The topsoil that pretreated reed wetland recovers region is excavated, using bull-dozer by pretreated reed wetland recovery district
The topsoil in domain is elapsed in the horizontal direction, and the soil that will be boosted piles some discontinuous trapezoidal mesa-shaped mounds,
It is 30-40cm to elapse the depth excavated；
4th, the trapezoidal mesa-shaped mound that heap comes highly is 25~50cm, and the content of organic matter for piling up soil typically all compares
Relatively enrich, soil fertility preferably, can be used for wetland economic plants plantation land used.
5th, the area in passage region is according to degraded wetland or needs the Wetland Area for recovering to set, without size limitation.
The underground rhizome of reed is presented shape of crawling and spreads stretching, extension, well developed root system, and with very strong vitality, root area scope is very
To the soil layer for having exceeded below 1m；From earth's surface to the region in the interval range of underground 30cm being reed root system most integrated distribution,
Mostly tiny, the thin and weak rhizome of this region Reed rhizome, is also that the region concentrated is piled up in the dead accumulation of reed root system.In underground
30cm to 40cm is the region that the thick big and strong rhizome distribution of reed is most concentrated.
The present invention has the characteristics of expanding ability is big, and fertility is stronger using sturdy very large reed root, by reed
Ploughing deeply for reed root portion topsoil, removes tiny thin and weak rhizome in upper soll layer, makes thick big and strong rhizome pole near surface,
Spring can germinate rapidly, extend the mitogenetic long-time of overground part, so that it is short to solve slow, the individual growing way of reed spring delay germination
The problems such as wetlands degradation such as small, biomass is not high, vitality is not strong.
Beneficial effects of the present invention：
The present invention is removed tiny, the thin and weak rhizome in reed root using excavation removal mode is ploughed deeply, and acceleration is dead, is
The growth of healthy, sturdy root system provides growing space, reed germination is can speed up in spring, during extension reed aerial growth
Between, increase the biomass of reed.The soil of passage is piled into discontinuous trapezoidal mesa-shaped, Wetland waterbird on the one hand can be kept
Connectivity, increases holdup time of the water body in wetland, moreover it is possible to which the aquatile to suitable different hydrology landforms creates various lifes
Border, for the plantation of wetland economic plants provides space.The method can effectively prevent reed community from degenerating, and recover to arrange in human assistance
With the help of applying, phytobiocoenose updating ability can be accelerated, particularly to the reed community for having begun to degenerate, with significant
Recovery effects, are conducive to wetland protection and restoration.This method simple operation, with low cost, recovery are quick.
Using the method for the present invention, in recovery district more than 85% degraded wetland is restored then, and recover
Area's spring reed germinating time at least shifts to an earlier date 10-15 days, and reed height ring improves more than 30% than improving 30-40cm, biomass.
Recovery effects are extremely notable.
Brief description of the drawings
Fig. 1 be embodiment 1 in by reed wetland recover region topsoil elapsed platform in echelon in the horizontal direction
The schematic diagram of shape mound；Wherein 1 is trapezoidal mesa-shaped mound, and 2 is initial soil surface, and 3 is the soil surface after excavating.

Mo Moge Nature Reserves degeneration reed wetland in Jilin Zhenlai recovers case.
First, at the beginning of 2015 and 2016, in Momoge Nature Reserve test block, in large area reed
In reed wetland, 4 pieces of reed wetland regions with significant degradation trend are selected respectively, be used as recovering land used.
2nd, the dry branches and fallen leaves that will recover on practice ground is removed, and is easy to carry out further work using bull-dozer.
3rd, before the germination of spring reed seedling (at the beginning of 4 months), the topsoil that pretreated reed wetland recovers region is excavated
Earth, is elapsed the topsoil of recovery district using bull-dozer, and the soil that will be boosted piles discontinuous trapezoidal mesa-shaped mound；
The depth of the excavation is 40cm, and the trapezoidal mesa-shaped mound that heap comes highly is 30cm, and schematic diagram is as shown in Figure 1；2015
Complete 2 pieces and recover experiment, complete within 2016 2 pieces, every piece of land area is 8m × 10m=80m2, between every piece of wetland recovery area
Water body be connected, water level is identical.
4th, result of the test shows that the spring germinating time of reed vegetation is advanced by 10-15 days in recovery district, and reed is highly
Ring improves more than 30% than improving 30-40cm, biomass.By using removal method is ploughed deeply, can just make then 85% in recovery district
Degraded wetland above is restored, and recovery effects are notable.
