Description
Technical field
The present invention relates to the bio-diversity of one's native land child care and the forest restoration and reconstruction technical method that afforestation organically combines on the spot of the secondary shrubbery of Sloping field in mountain area, belong to forestry (afforestation and forest training) field.
Background technology
Forest recovers to refer to the utilization ecological principle, in the location of suitable recovery forest, by protecting existing vegetation, closing hillsides to facilitate afforestation or build forest plantation, repairs or rebuild destroyed or destroyed forest, recovers the function of its bio-diversity and the ecosystem thereof.There is large-area deserted mountain barren hill Shrub Grassland in China, is mostly deforestation and destroys the secondary shrubbery formed.Therefore, accelerating the secondary shrubbery of deserted mountain barren hill is the fundamental way that improves China's forest coverage to the forest recovery.
Early the forest recovering method of development is the palace side of body clear (Miyawaki) method in the world, namely according to the vegetation succession renewal theory, adopt the seed of local indigenous tree species to carry out feeding block seedlings raising, be equipped with suitable soil transformation, then by afforesting, set up the climax type that is adapted to local climate within a short period of time.Just carry out applying in the environmental protection forests reconstruction seventies in last century in some cities of Japan, afterwards application in the tropical forest on the ground such as Bangkok of Malay Sarawak, Thailand recovers again.China in Beijing, the ground such as Liaoning Ma'an Mountain, Shanghai and Shandong also carries out the revegetation of zonality in this method on probation.Many Case comparisons the analysis showed that, the method is suitable for the ecosystem that forest decay is lighter usually.Past over 50 years China successively carried out the national Ecological Project Construction that forest is relevant; as three Norths shelter-forest project, Upper Yangtze River shelterbelt construction, wildwood protected project, green barren hill engineering, Rocky Desertification Control engineering etc.; carry out large-scale deserted mountain barren hill afforestation, significantly improved the forest coverage of China.The Technical regulations for afforestation adopted is mainly derived from traditional timber forest construction method for designing, and afforestation initial density in planting high (usually being greater than 3300 strains/hectare), seeds are single, and whole ground intensity is large.Such afforestation also is not equal to the forest restoration and reconstruction.Aspect engineering test research, nineteen sixty starts in Guangdong little good, Heshan for south China tropical plants research institute of the Chinese Academy of Sciences and experimental study is carried out in coastal erosion on the ground, set up forest plantation, the main technical method adopted is exactly the refining mountain prepare for afforestation technical method of Southern Collective Forest Regions, adds that habitat improves technical method.The 1970-1980 age, the Chinese Academy of Sciences is geographical carries out each (wet-land pine tree, masson pine etc.) artificial afforestration test with the upper mode of blast seed bed preparation that adopts in grass hillside fields, Subtropic Area of Jiangxi Province red soil hills, the Study on Resources place (thousand cigarette continents), restoration and reconstruction forest plantation, also the main refining mountain prepare for afforestation technical method that adopts carries out in conjunction with Water-retaining Measure.Yang and Liang also, on the red soil bare area of Jiangxi serious degradation, take comprehensive biology and engineering measure, plantation pioneer's mesquite seeds and this soil species camphor tree, and result has confirmed the success of revegetation.In recent years, on Abandoned Land of Mine and municipal refuse disposal area, having carried out soil matrix treatment technology method is forest or the filling thick grass reconstruction test of core, also obtains certain effect.Wang Tiehang studies discovery, and the mycorrhizal fungi of inoculation screening can effectively promote subtropics to corrode the revegetation of red soil.Ecotone is taked the method for integral agroforestry ecosystem to recover vegetation and is proved to be effective between farmland and forest ,Nong district and grassland.Review the past forest restoration and reconstruction over 50 years, the forest that is starting point based on secondary shrubbery recovers, in practice, to have formed some effective forest technical methods.Be summed up, mainly contain two different forest restoration and reconstruction technical methods.
The one, the forest recovering technology method of high density afforestation again after the shrubbery of intending afforestation carries out pre-treatment on the ground.Namely, by intending the secondary shrubbery of one's native land of afforestation or open forest land ground, processing, meet the needs of reproducting tree species cultivation and late growing stage.This technical method comprises each technical method modification of various pre-treating methods and reproducting tree species combination.Wherein, extensive use for a long time is refining mountain prepare for afforestation technical method.Mainly, by Shrub Grassland is carried out to controlled baked wheaten cake, suppress ground vegetation and grow, improve soil condition, carry out highdensity purpose species of trees cultivation, go to build forest plantation, realize that forest recovers, especially in the torrid zone, south China subtropics Collective Forest Regions.Although have closing early, grow into forest fast, the forest early growth is fast, the advantages such as forest form is neat, but the interference strength on whole ground, refining mountain is large, not only destroy bio-diversity of one's native land and upgrade brood body (as soil seed bank, soil seed pool), destroy the nature updating ability, the aggravation Topographic factor, also because planting density is large, seeds are single, often form the pure forest of single seeds, thickness of stand is large, tending management after growing into forest requires to have high input, also exist damage by disease and insect to threaten, diversity is poor, fire threatens large, the outstanding consequences such as the middle and later periods productivity of forest stand is low, this is the basic reason that current China large tracts of land south Low-efficiency forest forms.In southern subtropical zone, entirely cut shrubbery and top grass on planting site, high density afforestation then, and the filling grass that 3-6 regularly removes the growth of restriction purpose sapling afterwards after afforestation is also that a kind of extensive employing prepare for afforestation is main forest recovering technology method.The major defect of the method is also to destroy original plant nature updating ability, and planting density is large, fosters the large input cost of intensity high after afforestation, also mainly forms the single forest of highdensity seeds.And in loess plateau and Mountainous Area in North China, fish scale pit prepare for afforestation technical method (in conjunction with the runoff assemblage method) is also a kind of wherein forest recovering technology method extensively adopted.All in all, these existing forest restoration and reconstruction methods, all too rely on high density afforestation, fail to take into full account the lasting needs of diversity child care and ecological functions recovery, the forest later stage Tending measures formed is not caught up with yet, often form low yield poor efficiency standing forest, can't meet ecological public welfare forests restoration and reconstruction target.
It is main technical method that another forest recovering method, the deserted mountain barren hill that utilizes exactly nature renewal and recovery capability to carry out are closed hillsides to facilitate afforestation.Main passing through supplemented seed, then protects, and stops artificial disturbance, allows Shrub Grassland naturally revert to the technical method of forest of one's native land.The method Application effect greatly be decided by planting site and periphery whether have enough provenances with and natural updating ability, main characteristics are to preserve bio-diversity of one's native land, reduce artificial inappropriate interference, although suitable some local the achieving success (adopting the Pinus Yunnanensis Forest of scattered seeds by airplane for afforestation formation as the area, Xichang Sichuan) of condition, most of regional the method are effectively real.The major defect of this technical method is, provenance is supplemented failure mostly, too relies on the natural updating ability of remaining seeds, and forest recovery process is long, grows into forest slowly, can't reach the effect of forest recovery fast.Advantage is that the forest recovered has higher bio-diversity of one's native land, finally can meet the restoration and reconstruction target of ecological public welfare forests.
By comparison, above-mentioned two class main method have advantage and shortcoming separately.Developing ecology public welfare forest restoration and reconstruction technical method, overcome above-mentioned shortcoming, and the ecological public welfare forests restoration and reconstruction technical method that searching mountain area Protection of Diversity and ecological functions are optimized for target is the fundamental solution of avoiding China's Traditional Man afforestation woods disastrous effect.
The southwest national forest area is the second largest forest zone of China, and rich biodiversity, peculiar property are high, be with a varied topography in the ，Dan district, one of key area of China and even global Protection of Diversity, high slope, mountain is steep.The forest clear felling impact that long-term country is leading, a large amount of forests, by unreasonable felling, are cut down rear forest land severe water and soil erosion, upgrade not in time often 3-5 and just form the secondary shrubbery of large tracts of land.Test for many years through the 1960-1970 age, developed except inferior high mountain slash prepare for afforestation technical method, namely in the 1-2 that cutting blank forms, carry out rapidly the afforestation technology method (Yang Yupo of " large cave " whole ground, " two planting " (cave plants 2 strains simultaneously), 1985), the zone in large-area applications, effectively restoration and reconstruction the large tracts of land Man-made spruce forest, but this method is failed in the application formed for many years after clear felling on secondary shrubbery thick grass degeneration slash substantially, because the dense inhibition seedling growth of shrubbery.Although the forestry cadres worker is through for many years forest restoration and reconstruction effort, when proparea still have large-area secondary shrubbery (only the Aba Prefecture shrubbery accounted for the forest land gross area 48%) need to accelerate forest and recover, remove to meet the needs that region ecology safety barrier that country formulates is built.Proposal this go sociales that shrub forms that the rose, raspberry, barberry, currant, thorny elaeagnus, willow etc. of thorniness are arranged, and the difficulty of directly afforesting is very large, and success rate is low; And arbor provenance deficiency in shrubbery, it is poor that seed is settled down with growth conditions, by the nature resume speed, recovers slowly after closing hillsides to facilitate afforestation; Because the shrubbery crown density are large, Litter-fall covers many, and decomposition of soil organic matter is slow, the soil supplying nutrient capability deficiency, the shrubbery root competition is violent, causes the poor phosphorus of nitrogen starved plot, therefore, not only directly survival rate [of plantation is low, and nursery stock is also because of shrub restriction poor growth, undergrowth.Problem for above-mentioned existence, on the basis of test for many years, develop contour interconnected forest cover recovering technology method, can form effectively fast the mixed forest ecosystem of multi-level rich biodiversity of one's native land, thereby reach the purpose of the secondary shrub forest of fast quick-recovery degeneration.
Summary of the invention
For the excessive outstanding problem of diversity destruction, severe water and soil erosion, planting density that the secondary shrubbery in hillside fields is directly afforested and traditional prepare for afforestation causes, this patent proposes nature and recovers to be the forest restoration and reconstruction technical solution of target, to have overcome the defect that traditional technology method brings with the ecological public welfare forests of artificial afforestration combination.Specifically horizontal wall inscription, along the existing shrub of contour direction felling and tall and big herbaceous plant, forms the forest growth belt of one fixed width, and a row retains original shrubbery, forms the leave strip of one fixed width, makes leave strip and growth belt alternately on slope.In leave strip, retain nursery stock of one's native land and treelet and original bio-diversity component; And in growth belt, on the basis that retains the arbor treelet, use conventional hole to plant trees with bare root seedlings of one's native land, so all the time, make the forest land vegetation cover degree maintain higher level, along with natural deduction, the ecological protective functions of can form fast good Qiao, fill with grass, ground cover is multi-level is mixed forest preferably.
Therefore, the invention provides a kind of Sloping field in mountain area ecological public welfare forests restoration and reconstruction technical method, described method comprises the steps:
(1) leave strip and growth belt design and implementation alternately: in the gradient, be the mountain area of 5-15 °, shrubbery is dense, and the growth belt width is 4～6m, and the leave strip width is in 1m; In the gradient, be between 15-25 °, the shrubbery cover degree surpasses 90%, shrubbery is all under the situation of high 1.2～1.5m, the width of growth belt is at 1.5～5m, and the leave strip width is at 1.5～3m;
(2) afforestation: at first determine rational reproducting tree species initial density in planting according to arbor brood body situation in shrubbery and growth belt space size; Then in growth belt, plant hole and arrange by level or triangular arrangement, select transplanted seedling tree of one's native land; The general high nursery stock of 30-50cm, each plants the dark 40～50cm in hole, pitted surface diameter 30～40cm; Initial density in planting (cultivation hole) is general 1500～2100 strains/hectare.
In said method of the present invention:
In step (1), generally according to the gradient (and slope aspect) and shrubbery average height, determine leave strip and growth belt design width.The gradient of concrete implementation basis actual measurement and adjust the leave strip width, according to the light requirement biological property of purpose reproducting tree species seedling treelet phase and the width of shrubbery average height adjustment growth belt.Therefore this method comprises leave strip and the various width of growth belt and combination and forming thereof.
In step (2), in growth belt, with digging with cultivation, also can dig pit in advance and plant rainy season.Initial density in planting (cultivation hole) general 1500～2100 strains/hectare.Purpose species of trees seedling planting density need to be adjusted according to the existing arbor brood body density of forest shrubbery, original arbor Propagule number is many, cultivate the corresponding minimizing of nursery stock quantity, but cultivation nursery stock quantity generally should be less than 2500 strains/hectare, otherwise can be too large because of density, the undergrowth development after suppressing to grow into forest.Comparatively speaking, deciduous species can be smaller than coniferous species planting density; Seedlings are better than seedling cultivation effect.
In the said method application, the main purpose of leave strip is to retain bioenergy diversity of one's native land and resource thereof, and original sapling of one's native land, treelet and fertility (seed), also plays the effect of the conservation of soil and water; And in growth belt, during felling, specific aim retains arbor treelet and seedling, and after carry out the cultivation of purpose species of trees seedling.
Said method provided by the invention can be preserved on the spot existing bio-diversity of one's native land and, in resource, avoid excessively causing water and soil loss wholely, saves whole ground, afforestation and management cost, has overcome the prior art defect.Also can accelerate the formation of the multi-level mixed forest of Qiao, filling, grass, Litter-fall, improve forest restoration and reconstruction efficiency, make the forest of restoration and reconstruction have better diversity child care and Ecosystem Service.
It is that starting point be take the forest restoration and reconstruction of public welfare forest as target that the present technique method is adapted to the vast Sloping field in mountain area shrubbery of China, its technical method key is to determine the hillside fields shrubbery pre-treatment scheme before afforestation according to terrain slope (slope aspect), shrubbery average height, purpose species of trees light requirement situation, determines appropriate planting density according to upgrading brood body situation and growth belt space.
The key of the technology of the present invention method is that the hillside fields shrubbery pre-treatment before afforestation is definite with appropriate planting density.According to shrubbery, topography and geomorphology (gradient, slope aspect), purpose cultivation seedling growth, need to determine leave strip and growth belt allocation plan, therefore different allocation plan modification is arranged.And according to determining the afforestation initial planting density in situation and the growth belt space of the renewal brood body (treelet, seedling) in existing shrubbery, so planting density according to circumstances changes.
With existing other technology, compare, its advantage (novelty) is: 1) natural recovery, the child care of diversity resource and purpose species of trees afforestation are organically combined; 2) foster afforestation, young growth area printing opacity link to organically combine, reduce current cost of forestation; 3) significantly save the afforestation management cost; 4) forest of one's native land formed is mixed forest, and forest structure (Qiao, filling grass, Litter-fall) is preferably arranged, and can more effectively bring into play Biodiversity Conservation and the ecology service effect of public welfare forest.
