Abstract
A method for establishing fire barrier area belongs to the fire barrier technology of forest and grassland. The existing fire barrier area is difficult to control and easy to cause forest fire due to fire break-out. The invention comprises the following steps: removing the vegetation on the barrier area before fire protection period in fall and winter when the vegetation stops growing; arranging a plurality of vegetation retaining strips in the middle of the barrier area; respectively arranging one vegetation cleaning stripe at the two sides; and burning off the vegetation cleaning stripes together with the removed vegetation after the removed vegetation naturally becomes dry. The method has pretty high reliability; and the fire break-out does not tend to happen when burning off the vegetation, thus the forest fire can be prevented; moreover, the method can save large amounts of money and man power.
Description
Technical field
The present invention relates to forest and grassland fireproofing isolation strip establishing method, especially a kind of in the non-fire prevention phase, planned burn off isolation strip vegetation, with the method for fiery fireproof burn fire barrier.
Background technology
The policy of " put prevention first, actively eliminate " and " put prevention first, combine prevention with fire fighting " is carried out in forest and grassland fireproofing work.At forest and meadow and edge area thereof, set up the fire-blocking belt by certain limit or area, be the important measures and the facility of prevention forest fire.The mode of setting up of various places forest and grassland fireproofing isolation strip has following several at present:
1, opening up immature soil band is before fire prevention season or the arriving of fire prevention phase, and all vegetation on the isolation strip (trees, grass filling etc.) have been grubbed out, and removing is clean, formation immature soil fire guard.
2, fire forest belt is that biological fire guard is the strong plant of anti-firepower such as Schima superba of planting in the isolation strip, forms fire-proof curtain.
3, burn fire barrier is in the fire prevention phase, and in a planned way vegetation in the burn off isolation strip with the fire fire prevention, is eliminated flammable thing, reaches the purpose of isolating burning things which may cause a fire disaster.This mode is applied to the north more, and Qin Tang village, Xinchang, Zhejiang Province county has " road of making a fire " custom in history, also belongs to same mode.
The first two kind in above-mentioned three kinds of modes has flameproof effect preferably, security reliability height, but the large quantities of manpower financial capacities of spend.The third mode is planned burn off, also can effectively prevent fires, and cost is lower, is convenient to large tracts of land and implements, but must carry out in the fire prevention phase, and it is bigger artificially to control difficulty.Owing to the easy runout in isolation strip this moment causes forest fire, so very big limitation is arranged.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is to be difficult to control in the time of will overcoming existing baked wheaten cake isolation strip, easily to run away and cause the disadvantage of forest fire, a kind of setting method of burn fire barrier is provided, in the non-fire prevention phase that does not stop fully as yet at vegetation growth, drying is cut off and let alone to vegetation in the isolation strip, then the burn off of lighting a fire reaches with the fire fire prevention, promptly before the fire prevention phase safety with fire, isolate burning things which may cause a fire disaster in the fire prevention phase, avoid the purpose of initiation fire.For this reason, the present invention is by the following technical solutions:
A kind of setting method of burn fire barrier, it is characterized in that before the autumn and winter forest fire prevention period plant growth latter stage prescinds that vegetation places on the isolation strip by the time air dry on the isolation strip, and before the arrival of fire prevention phase autumn and winter, give burn off, form the fire-blocking belt.The isolation strip vegetation prescinds the time with burn off, must be before fire prevention phase autumn and winter, and the plant growth stopped substantially, did not stop fully as yet this moment, no longer sprouted after the baked wheaten cake or grew new plant.This method is conceived to the obviously different of inside and outside vegetation drying in isolation strip and moist degree: in the isolation strip, vegetation was dry already during ignition, was easy to burn off; Outside the isolation strip, vegetation is moist dark green, still full of life, is difficult to burning, is difficult for runout.
As the further of technique scheme improved and replenish, the present invention includes following additional technical feature:
Leave leave strip in the middle of the isolation strip, the both sides, isolation strip are provided with the cleaning band.The vegetation of both sides, isolation strip cleaning bar will be cleaned out and put the centre and be gone.The vegetation of leave strip will not be removed, and when burning the isolation strip by the time, with other vegetation burn off in the lump, this measure neither influences the vegetation controlled prescribed burning, helps controlling burning things which may cause a fire disaster again, guarantees to use fire safety.The isolation strip interplantation is retained the bar number of band, decides according to isolation strip width and vegetation growth situation, and the isolation strip is wideer, the vegetation growing way better, then the bar number of leave strip can suitably increase.
The fire-blocking belt width is decided on situations such as vegetation growing way, floristics and the age of stands, is generally 10～30 meters; Leave strip is 1～5, and is wide 0.5～1 meter; The cleaning band of both sides respectively is 1,0.8～1.5 meter of width.In south, be generally 10 meters～30 meters.
When spreading the vegetation that cuts off on the isolation strip, middle position is thicker than other position; And the part vegetation spread on the leave strip and near.
The time of cutting off of vegetation is 35～50 days before prevent fires autumn and winter phase on the isolation strip.At this moment, the vegetation growth phase is near finishing but do not stop fully as yet.After cutting off, can not sprout substantially then and make new advances plant or have only a small amount of sprouting.
Vegetation on the isolation strip will prescind from base portion.
Before preventing fires the phase 5～25 days isolation strip vegetation ignition time autumn and winter.Vegetation air dry this moment is no longer sprouted behind the burn off or is grown new plant.
During the isolation strip ignition, will be from high to low in the hillside fields, from top to bottom, carry out in afterwards outward earlier.
The day of isolation strip vegetation ignition is still keeping dark green state vegetation growth latter stage outside the isolation strip, does not arrive in the withered and yellow drying.
Burn the isolation strip and will select fine day or cloudy day, calm or few wind weather.Wherein fine day should be in the afternoon after 3 o'clock or the ignition at night.
During burn fire barrier, be in a organized way, have leader ground to carry out.Want both sides to guard, hand-held Fire extinguisher prevents runout, eliminates ember, guarantees safety.And must be through certain examination and approval procedures, strict carry out " forest fire protection regulations " and " grassland fireproofing regulations ".
Setting method of burn fire barrier of the present invention has in essence difference with conventional burn fire barrier method:
1, because have only this moment, plant could be burnt in the fire prevention phase igniting burn off time of igniting burn off asynchronism(-nization) conventional method; Before the inventive method is then arrived in fire prevention phase autumn and winter.
2, the isolation strip vegetation is handled different conventional method the isolation strip vegetation is not done any processing; The inventive method then will be cut off dry the processing earlier to the isolation strip vegetation.
When 3, the different conventional method of the inside and outside vegetation state in fire-blocking belt is lighted a fire burn off, entered the fire prevention phase, the inside and outside vegetation in isolation strip is withered consistent; The inventive method is when ignition, and forest does not enter the fire prevention phase as yet, but vegetation was dry already in the isolation strip, and plant still keeps dark green outside the isolation strip.
4, the special conventional method of isolation strip establishing method in the isolation strip and the both sides vegetation will not clear up, the centre also without reserve the band (bar); The inventive method is all established vegetation cleaning band (bar) in the both sides, isolation strip, the centre has 1～5 hedge planting to be retained band.
Though 5, the different conventional method of flameproof effect and security can reach certain flameproof effect, when burning the isolation strip,, run away and initiation fire easily owing to be in during the fire prevention, therefore must organize large quantities of personnel to be strictly on guard against control; And the inventive method when burn fire burns the isolation strip, was in before prevent fires autumn and winter phase, and plant does not stop growing as yet fully outside the isolation strip, still keeps dark green state.Be difficult for the runout initiation fire when therefore burning, artificial control is also easy, more safe and reliable.
The present invention possesses following advantage:
1, set up the fire-blocking belt, and processing ease is simple and easy to do:
2, with open up immature soil band, two kinds of conventional methods of fire forest belt are compared, and can raise the efficiency more than 500%, save large quantities of funds;
3 and conventional burn fire barrier compare, can save artificial and funds 50%～80%;
When 4, lighting a fire the burn off fire-blocking belt, be difficult for runout and the initiation forest fire, the security reliability height.
Effect mechanism of the present invention is:
Forest fire takes place three big factors are arranged: forest fuel, weather conditions conducive to wildfires and burning things which may cause a fire disaster.This three big factor possesses just simultaneously, and forest fire can take place.Wherein combustible (comprising plants such as trees, grass filling) is the material base that forest fire takes place.Combustible and burning things which may cause a fire disaster can artificially be controlled.The inventive method mainly is based on the control to combustible.Promptly, let alone drying, make it in the non-fire prevention phase, to possess flammable condition by before the fire prevention phase, cutting off the isolation strip vegetation.Vegetation outside the isolation strip still is in the latter stage of growing at this moment, does not arrive withered and yellow season, is keeping dark green state, does not possess or do not possess substantially flammable condition.So utilize this opportune time, vegetation in the burn off isolation strip (unlikely again after baked wheaten cake the germination and growth plant that makes new advances) then smoothly just; Vegetation then can not be burnt or nonflammable outside the isolation strip, easily control.And also be provided with vegetation reservation bar (band) and cleaning bar (band) in the isolation strip, further strengthened security with fire.Thereby can avoid runout and cause forest fire, reach the purpose of setting up the fire-blocking belt.
