Abstract
The invention relates to a method for recovering cold temperate zone forest wetland vegetation after extremely severe fire. The method mainly comprises the steps of recovery border determination, field cleaning, tree species selection, seedling planting configuration, soil preparation, seedling planting, tending management and the like. The method for recovering the cold temperate zone forest wetland vegetation after the extremely severe fire aims at solving the problems that spontaneous recovery time is long and retrogressive succession is caused after cold temperate zone ecologically vulnerable area forest wetland severe degeneration, and can recover the vegetation as soon as possible, build an optimized wetland vegetation community structure, effectively improve stability and self maintenance of the degenerated forest wetland, achieve positive succession development, and rapidly recover ecosystem functions.
Description
Technical field
The present invention relates to a kind of cool temperate zone area and suffer the forest wetland method for recovering vegetation after utmost point severe fire, belong to ecological construction technical field, be specifically related to a kind of utmost point severe and burn rear cool temperate zone forest wetland method for recovering vegetation.
Background technology
Current, after fire, revegetation is the focus and emphasis problem of countries in the world Fire ecology research.China starts late at this area research, after fire, revegetation research focuses mostly in forest and grassland ecosystem, to the research of wetlands ecosystems revegetation after fire seldom, and for the more aobvious weakness of research of cool temperate zone wetlands ecosystems, correlative study is scattered, lack systematicness, research contents more relates to the rear Nutrient Cycling of fire, after fire, soil physico-chemical property changes, characteristic of plant communities variation and vegetation succession process etc. after fire, the factor of influence recovering for muskeg after fire is shorter mention, for theory and technical research that after severe and utmost point severe baked wheaten cake, cool temperate zone forest wetland recovers, be short of especially.
China cool temperate zone forest wetland forest is mainly distributed in Daxing'an Mountainrange, aspect the ecological balance of maintenance area, playing an important role, a little less than its ecosystem is highly brittle, severe and utmost point severe baked wheaten cake can cause forest wetland ecological functions obviously to be degenerated, after fire, revegetation not only takes very long, and succession process has very large uncertainty, even there is reverse succession and cause forever cannot recovering.In brule wetlands ecosystems recovery process, revegetation is always prior to the recovery of ecosystem function.Revegetation after fire, particularly after fire, the recovery of early stage vegetation is prerequisite and the basis that ecosystem function recovers, and only has after forest wetland is covered by vegetation, the impetus of its deterioration of the ecological environment could be checked effectively, to forward succession future development.
Take Dahurian larch (Larix gmelinii) softwood forest as main cool temperate zone forest wetland is after being burnt by utmost point severe, be injured standing tree more than 90%, almost all dead.The maximum constraints factor that utmost point severe is burnt rear forest wetland recovery is provenance, especially acerose provenance, this is because the seed of preserving in soil is almost all burnt, even have needle elite stand to exist inside and outside burning district, the propagation distance of its seed is also very limited, and vegetation is difficult to nature and recovers.For example, the propagation distance of Larix Gmelini Rupr. seeds only has 100～150m.The quick revegetation of method of taking science is the key that forest wetland recovers.
Summary of the invention
Technical problem to be solved adopts following technical scheme to realize:
Utmost point severe is burnt a rear cool temperate zone forest wetland method for recovering vegetation, mainly comprises and determines steps such as recovering border, site clearing, choice of tree species, the configuration of planting seedlings, whole ground, the method for planting seedlings, tending management; Concrete operation step is as follows:
(1) determine and recover border:
Cool temperate zone forest wetland fire standing tree more than 90%, the residue standing tree of living of being injured does not reach sparse woods standard, and also there is no the baked wheaten cake district of renewal;
(2) site clearing:
Wood, wooden is burnt in cleaning to death, retains the standing tree of living, and promotes the recovery of vegetation;
(3) choice of tree species:
According to matching species with the site principle, select the coniferous species Dahurian larch of cool temperate zone forest wetland climax community, with Dahurian larch nursery stock for the object that plants seedlings;
(4) configuration of planting seedlings:
Adopt rectangle or square configuration, seeding row spacing 2 * 1.5m or 2 * 2m;
(5) wholely:
Adopt circular cave-shaped land preparation mode, Jing He cave, cave deeply all more than 30cm, plant seedlings previous month whole ground or with whole with planting seedlings;
(6) method of planting seedlings:
Spring or rainy season, adopt slit planting, in the circular pocket on whole ground, with uprooting or spade cracks, puts into nursery stock, and the depth is suitable, nest root not, puller, steady and sure soil; While planting seedlings, as soil drought, should water in time;
(7) tending management:
After planting seedlings, weed with a hoe in time, continuous 3 years, annual 1 time.
As optimal way, the described Dahurian larch nursery stock specification of above-mentioned steps (3) is I, the biennial bareroot seedling of II level Dahurian larch of GB 6000 regulations.
The object of the invention is to avoid after the forest wetland heavy-degraded of cool temperate zone ecologically fragile areas, only depend on nature length recovery time, cause reverse succession problem, a kind of method for recovering vegetation that suffers the forest wetland after utmost point severe fire for cool temperate zone area is provided, recover as early as possible vegetation, build muskeg structure of community, the stability that effectively improves degeneration forest wetland and the self-maintenance optimized, to forward succession development, reach the fast quick-recovery object of ecosystem function.
