Description
Technical field
It the utility model is related to a kind of utensil of field herbosa investigation, the field life for the successive sampling that is particularly suitable for use in
Herbosa's investigation sample prescription frame of state investigation.
Background technology
In ecology, agricultural, forestry, the teaching and scientific research process of environmental science, field setting is frequently referred to
Sample prescription carries out Ecological Investigation, the problems such as studying the quantity of bio distribution, Population Distribution Pattern, growth characteristics, species diversity.It is wild
Outer sample investigation is the required investigative technique that the firsthand information is obtained on a species ecology, can fast investigation go out each ecology and refer to
Mark, full and accurate foundation is provided for scientific research.Especially herbaceous plant is investigated, the respondent's species being related to are more, individual is more,
Individual is small, and Comparision is numerous and diverse.In subtropical zone and Temperate Region in China, because the change of landform is bigger, generally, using quadrat method or
Belt transect method, 0.5m × 0.5m, 1m × 1m, 2m × 2m sample prescriptions or 0.75m are set2, 1m2Belt transect carries out field investigation.If investigation pair
As less, workload it is little in the case of, typically measuring back gauge in investigation sample using instruments such as tape measure, lining ropes, determine orientation
And four edges.
But even if so, boundary line and orientation are not easy accurately to control, easily occur sample prescription boundary line do not close, sample prescription
Irregularly, survey data is not accurate enough, and operating process is comparatively laborious, and operating efficiency is low.And the sample prescription frame that Four built in boundaries is good, volume
It is larger, carry and use is inconvenient, topography variation and the needs of different research methods can not be complied with.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of it is easy to carry, be unlikely to deform, can Rapid Combination
Portable folding herbosa investigates sample prescription frame, and the investigation sample prescription frame can also be adapted to successive sampling field investigation.
In order to solve the above technical problems, the utility model provides a kind of portable folding herbosa investigation sample prescription frame,
Including some fix bars and some interval ropes, all fix bars, which join end to end, forms a rectangle frame, and the interval rope is solid respectively
It is scheduled on two relative frames of rectangle frame, the interior zone of rectangle frame is being divided into some area equations just by the interval rope
Square subquadrat.
After such structure, take more fix bars to form end to end rectangle frame, major quadrat surrounded inside rectangle frame,
Recycle interval rope that major quadrat is divided into the subquadrat of suitable successive sampling field investigation.
Advantageous effects of the present utility model are：1st, it is easy to carry and stores, both facilitated excursion, field work to take
Band, it is easy to laboratory to store again；2nd, it is unlikely to deform, fix bar is from the relatively low material of deformation coefficient.Make in compared with prior art
Being measured with sample rope and tape measure, easily influenceed by vegetation, pulled band of stumbling, be easily deformed, border and orientation are not easily controlled,
Easily cause sample prescription boundary line do not close, sample prescription it is irregular；3rd, can Rapid Combination, easy to operate, can be quick in a short period of time
Sample prescription is combined into, lifts field work efficiency；4th, distinct methods Ecological Investigation needs are applicable to, has and is adapted to investigation graduated scale
Note, it is convenient and practical, in order to continue to divide subquadrat.The quadrat size commonly used according to vegetation pattern, marked on housing per 20cm
Bright 1 scale, facilitates installation interval rope, can continue to divide 20cm × 20c m subquadrats, different to adapt to population or Community Survey
The needs of method, different scale, it is applicable especially with successive sampling, measure relative frequency, Population Distribution Pattern etc.,
Meanwhile it is also convenient for investigating and recording one by one；5th, the needs of different area shape are applicable to, can be according to landform needs, such as field
The ridge or field dam, the region of not easy-to-draw sample prescription can be by the fix bar number of rectangle frame each edge frame, to change the face of major quadrat
Product, is easy to flexible modulation；6th, advantage of lower cost；7th, environmental protection concept is met, each sample block components do not form compacting to vegetation
Or damage, vegetation damage rate is smaller, almost zero damage, meanwhile, during making and use, do not produce poisonous and harmful
Material, it is no pollution to environment and investigator itself；Meanwhile sample prescription frame can repeatedly use, in addition to sample prescription frame
Component elements undertake other purposes in can also working in the wild, the utilization of resources can maximize.
In order to be more clearly understood that technology contents of the present utility model, this portable folding herbosa is investigated into sample below
Square frame is referred to as this sample prescription frame.
Part is bolted between the arbitrary neighborhood fix bar of this sample prescription frame to be connected；After such structure,
Bolt connection piece can be when this sample prescription frame be worked, and angle is fixed between ensureing two fix bars, can also adjustment bolt connection
Part makes to relatively rotate between two fix bars, facilitates this sample prescription frame to fold, similarly also dismountable bolt connection piece, make fix bar it
Between remove contact, convenient dismounting storage.
The fix bar outer wall of this sample prescription frame is provided with the scale mark for being adapted to investigation；After such structure, it can facilitate
Interval rope is fixed.
Graduated scale is corresponded in the fix bar of this sample prescription frame the dovetail clip coordinated with interval rope, interval rope both ends difference are installed
It is fixed on and is relatively fixed on bar by dovetail clip；After such structure, reached by coordinating between dovetail clip and fix bar
To the purpose of fixed intervals rope, dovetail clip has the advantages that easy to use, stable connection.
The portable folding herbosa investigation sample prescription frame of this sample prescription frame also includes some hold-down bars, and the hold-down bars is in
On the inside of the rectangle frame that fix bar surrounds, ground, the hold-down bars side wall and adjacent two fix bars are stretched into described hold-down bars one end
Link position contacts；After such structure, hold-down bars can make the junction of two neighboring fix bar not restricted at interval
In the presence of rotate or displacement, it is ensured that measurement result it is accurate.
