Description
Technical field
The utility model belongs to monitoring plant cover degree technical field, more particularly to a kind of to be used for field measuring moss crust lid
The portable sample prescription frame of degree.
Background technology
Quadrat method is the conventional method of phytobiocoenose investigation.At present, it is common to use monitoring Steppe Plants cover degree cover degree
Frame is using the iron plate frame of self-control 1m × 1m, and cover degree frame weighed about as 10 kilograms, and structure is clumsy, every time on not Portable belt when going down the hill, survey
Timing need to have a staff specially to carry, laborious time-consuming.Also there is use " flexible PVC biological breadcrust cover degree measures frame "
Technology, but it is excessive still cannot to solve sample prescription frame area, it is impossible to folded, the problem of field test is inconvenient to carry.
Common meadow sample area investigates flora based on 25cm × 25cm, 50cm × 50cm and 100cm × 100cm
" four degree of one amount " (cover degree, more degree, density, height and the biomass) fallen.The general point of use needle-like of measure of moss crust cover degree
The estimation of frame method, sample frame length of side 30cm, grid specification 2.5cm × 2.5cm, each each probe for fixing a 5cm of sample prescription node,
Totally 169 probes；During measure, moss crust is sprayed with water first, unfolds its blade that absorbs water and becomes with leaf color form generation
Change easy to observation；Then sample frame is vertically disposed on Yang Fang to be measured, observes and record the area that bryophyte lives in Yang Fang, estimate
Calculate the cover degree of moss crust.This method is typically used in an experiment, but since sample prescription frame and pin block vision are not allowed
Easily observation, and pin insertion soil fail moss crust is generally required during earth's surface unevenness, to fragile Qinghai-Tibet ecology
Environment causes destruction.
Utility model content
In view of the deficiencies of the prior art, the purpose of the utility model pin, which there is provided, a kind of is used for field measuring moss crust
The portable sample prescription frame of cover degree, it is characterised in that the sample prescription frame is formed by two half identical sample prescription frame vertical cartels, its
In, half sample prescription frame is to be connected and composed two parallel isometric straight tubes using evenly spaced rope yarn.
Scale is carved with the straight tube, and is uniformly punched, wherein, pitch of holes grid specification according to needed for sample prescription frame determines,
Carve graduated straight tube and can be used for measurement length, width.
The rope yarn is fixed on each hole of straight tube, and rope yarn interval is uniform.
Described two half identical sample prescription frame right angles are fixed using angle coupling, during in-site measurement, can quickly be assembled
Form sample prescription frame.
The region of different measurement areas can be directly distinguished on the rope yarn by dyeing, meets different measurement demands.
The sample prescription frame frame is the straight tube to form square, and centre is the rope yarn for forming uniform grid.
The beneficial effects of the utility model are：Portable sample prescription frame provided by the utility model is carried out using rope yarn and straight tube
Simple combination forms, simple in structure, easy to make, easy to carry, suitable field work easy to operate, can speed progress different area
Detection, meet the needs of not having to area sample frame, realize that a frame uses, crosspoint is tiny, and measurement result is accurate, especially suitable for
Field to moss crust cover degree, divide the measurement of cover degree.
Brief description of the drawings
Fig. 1 is half of sample prescription mount structure schematic diagram of 50cm*50cm prepared by embodiment 1；
Fig. 2 is the netted sample prescription mount structure schematic diagrames of portable 50cm*50cm being composed in embodiment 1；
Reference numeral：1- nylon rope yarns；2- aluminum pipes；3- vertical joints.
Embodiment
The utility model provides a kind of portable sample prescription frame for field measuring moss crust cover degree, with reference to attached
Figure is described further specific embodiment of the present utility model.
Embodiment 1
The small aluminum pipe that four root long degree are 50cm is chosen, scale is carved with aluminum pipe, and punched on aluminum pipe every 2.5cm；Choosing
Two aluminum pipes are selected, are placed in parallel, the parallel stays between aluminum pipe, nylon rope yarn interval is uniform, sample of the row into half of 50cm*50cm
Square frame, as shown in Figure 1；
During in-site measurement, another identical half sample prescription frame is disposed vertically with above-mentioned half sample prescription frame, and by straight
Angle joint quickly combines adjacent aluminum pipe, forms the netted sample prescription frames of 50cm*50cm, as shown in Figure 2；Wherein share 400
The sample square frame of 2.5cm*2.5cm, and nylon wire, by dyeing, middle overstriking region, energy significant difference go out sample as shown in Figure 1, Figure 2
The region of 10cm*10cm, 20cm*20cm in square frame, meet different demands.
Using above-mentioned sample prescription frame, moss crust cover degree is measured by following steps：
(1) choose sample prescription with the method for grab sample, spray moss crust with watering can so that bryophyte formalness and
Color changes, and sample prescription frame is laid on sample prescription to be measured, surrounding sand hill or stone suppression by vane extension easy to observation
It is fixed；
(2) moss crust in careful right-angle view grid, carries out the data record of moss crust cover degree form, for not having
There is the position for covering any moss crust, then relevant position keeps blank in the table；Different sample prescriptions is chosen according to demand
Region uses 20cm*20cm, 10cm*10cm different size to carry out record measure；
(3) number of lattice is occupied according to the moss crust of statistic record to calculate the cover degree of moss crust；In addition may be used
Sample prescription frame is carried out with digital camera it is vertical, closely take pictures, photo is taken to and indoor carries out moss crust lid on computers
Degree measuring and calculating.
(4) after terminating measurement, angle coupling is removed, two and half sample prescription frames are directly rolled, are convenient for carrying；Make field
Operation is efficient, convenient.
