Specific implementation mode:
A kind of Karst Rocky Desertification Region woods grass-shrub vegetation implantation methods, it includes:
Step 1 determines the vegetation succession stage
Mainly synecology principle is used to understand Karst Rocky Desertification Region coenotype, structure, composition and species Etc. features situation of change, verify different ecological values, it is proposed that the compensation matching structure strategy of adaptation to local conditions. The karst vegetation natural deduction stage is divided into thick grass-sowing-shrubbery-Qiao's filling-high forest stage, with Karst vegetation Different phase COMMUNITY CHARACTERISTICS is different (table 1) from the rudimentary During Succession to advanced stage.It needs first to determine the vegetation succession stage.
1 vegetation succession phase characteristic of table
Step 2, vegetation selection
Karst Rocky Desertification topography and geomorphology complexity is various, and the determination of plant species will also be needed to different geology and soil Condition is chosen seeds.Possess thicker soil region in the negative land forms such as big stone ditch, stone pit, stone cistern, soil moisture content compared with Height is suitble to deciduous species Chinese toon, Chinese catalpa of fast-growing etc..
Larger to the gradient (>25°,<45 °), soil is by very thin (10cm), the area of rock exposed more serious (70% or more), Moisture easily flows away along scar, is only suitable for the climbing of the lianas such as the fleece-flower root, honeysuckle, kudzu.
Greatly (45% or more), water retention property is very poor, and pole is unfavorable for the breeding of vegetation and survives for chad content, and afforestation is difficult Degree is big, and such kind of area is then selected extremely drought-enduring, and the small coniferous species of transpiration rate such as Yunnan cypress, Huashan pine, pinus yunnanensis or leaf have one layer Seeds of wax coat or hard such as glossy privet, Quercus acutissima, Qinggang oak etc..
Step 3, plant society collocation
Plant is arranged in pairs or groups as unit of plant functional groups, distributes technology rationally, makes the collocation forms of species, density and residing Spatial position be in optimum state, form the space structure configuration mode of science.There is kind of a groups in vegetation recovery procedure Substitution law lacks the composed structure of natural vegetation group, and system stability is poor, easily occurs to degenerate and by pest and disease damage.
For the stereochemical structure unobvious of woods grass-shrub vegetation, part vegetation level missing, the region of arborous layer missing can It chooses fast-growing, adaptability, happiness calcium, drought-enduring vegetation to be planted, such as Ailanthus altissima, Chinese prickly ash, beans.
Some economical species can be planted for the region of shrub layer missing, adjust the structure of species, while solving the common people Livelihoods such as cuckoo, fiery spine, Yellow Fructus Gardeniae, five-leaved chaste tree, Coriaria sinica, Rosa roxburghii Tratt.
The maintenance on meadow can choose Cool-Season Forage Species and season type herbage according to local climate condition, drilling or disseminate, Grass family and the optimal proportion of leguminous forage are 3:1.
The three-dimensional collocation of step 4, massif space
According to the geomorphological structure feature of peak cluster depression, restoration of the ecosystem and industry development are considered, establish massif space Three-dimensional collocation mode.Specially:Steep slope region, long-term fencing;Compared with steep slope region, plantation water protects the strong honeysuckle of ability, wood The economic species such as beans, bamboo;Make medicinal material between planting high-quality fruit forest zones simultaneously in the gentle slopes area such as bealock, the foot of a mountain;It mainly sends out depression bottom Open up plant of grain crops.A variety of Comprehensive Management Modes are constructed with this, such as:Peak cluster mountainous region fruit+medicine ecological pattern, peak cluster Mountainous region is crushed plot fruit+dish ecological pattern etc..
In the deep massif lower part of soil layer based on the crisp Lee's kind of local ice, it is aided with the protection of the hedges band such as liana, shrub and arranges " the crisp Lee+honeysuckle of the ice " pattern applied;The middle and upper part gradient is larger, and long-term cultivation makes the exposed rate of rock become very big, is commonly called as " being nook ", using " deciduous species (Chinese catalpa, Chinese toon, alder)+evergreen species (Yunnan cypress, glossy privet)+honeysuckle " pattern; Mountain top soil is extremely rare, artificial measures can not be used to restore vegetation, should implement to close hillsides to facilitate afforestation, protect natural vegetation.
Step 5, woods grass-shrub vegetation planting
Fruit forest zones seedling growth generally uses cave-shaped site preparation, applies farm manure and make base manure, fertilizer amount of often spreading manuer in holes 3-5kg;Using 1 Year raw exposed root and shoot forestation, 60-100 plant per acre, plant accomplishes that the positive root of seedling relaxes, and layering adds soil, steady and sure, plants and uses stone, withered on plant hole Branch fallen leaves or covered rearing with plastic film;To use every year loosen the soil, foster, earthing up, the measures such as top dressing and pruning.
Woods grass-shrub vegetation it is multi-level, multifarious planting patterns contributes to the stability and stony desertification environment of vegetation Administer effect.So in the preferable area of edaphic condition, " fruit forest zones+Chinese prickly ash ", " fruit forest zones+economical herbage " and " flower are taken The administration way of green pepper+short bar industrial crops ".Form woods shrub complex ecological structure.
" seizing every opportunity " is answered in the larger location of naked stone rate, is made full use of remaining in stone ditch, crack of stone, stone cistern and stone pit Soil dense planting;The naked relatively small location of stone rate should then control the density of plantation in 900~1050 plants/hm2, to be formed Woods window realizes tall, filling, careless three layers of stereoscopic configurations.
