Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completelyDescribe, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment. Based onEmbodiments of the invention, those of ordinary skill in the art are not making obtain under creative work prerequisite every otherEmbodiment, belongs to protection scope of the present invention.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail, is illustrated in figure 1 embodiment of the present invention instituteThe detection method schematic flow sheet that meadow sample prescription cover degree is provided, described method comprises:
Step 11: the lattice that sample prescription survey area, meadow to be detected is divided into several formed objects;
Grass side that described sample prescription survey area, meadow to be detected is 1m × 1m investigation grid, and be divided into several are identical largeLittle lattice is the lattice of 100 10cm × 10cm.
Step 12: estimate the cover degree of certain species in this lattice in each lattice;
In this step, the cover degree of setting the species in each lattice is 0.5 or 1, and a point species statistics cover degree is 0.5 and 1Lattice quantity, specifically:
If accounting for the ratio of this lattice gross area, the upright projection gross area of certain species in a lattice be greater than 0.5,Cover degree by these species in this lattice is designated as 1;
If ratio is not more than 0.5, by these species, the cover degree in this lattice is designated as 0.5;
Add up respectively for different species that to obtain cover degree be 0.5 and 1 lattice quantity.
Step 13: the cover degree by certain species in each lattice is added summation, obtains these species described to be detectedCover degree in sample prescription survey area, meadow.
For instance, be illustrated in figure 2 the schematic diagram of the meadow sample prescription cover degree estimation that the embodiment of the present invention enumerates, for figureIn species A, first add up the upright projection gross area of species A in each lattice and account for this lattice gross areaWhether ratio is greater than 0.5, is greater than that the cover degree in this lattice is designated as 1 by species A; Be not more than and be designated as 0.5;
Then for species A, it is 0.5 and 1 lattice quantity that statistics obtains cover degree;
By species A, the cover degree in each lattice is added summation again, obtains species A and adjusts at described meadow sample prescription to be detectedLook into the cover degree in region.
By that analogy, can obtain the cover degree of all species in this sample prescription survey area, meadow to be detected. Owing to having cut apartThe estimation area of grid, adopts the method for selecting numerical value, so just can show more quickly and accurately that a certain species are in investigationCover degree in region.
The embodiment of the present invention also provides the checkout gear of a kind of meadow sample prescription cover degree, is illustrated in figure 3 embodiment of the present invention instituteThe structure of the detecting device schematic diagram of meadow sample prescription cover degree is provided, and described device comprises upper winding shaft 1, lower winding shaft 2, left support bar3, right support bar 4, the grid 5 that formed by warp and parallel, wherein:
The two ends up and down of described left support bar 3 and right support bar 4 are fixedly connected with lower winding shaft 2 with described upper winding shaft 1 respectively;
And it is square that described grid 5 is positioned at four limits that described upper winding shaft 1, lower winding shaft 2, left support bar 3, right support bar 4 formIn;
On described upper winding shaft 1 and lower winding shaft 2, be provided with the holddown groove point for fixing warp;
On described left support bar 3 and right support bar 4, be provided with the holddown groove point for fixing parallel.
In specific implementation, this left support bar 3 and right support bar 4 are to dismantle, further:
In the time that described checkout gear uses, described checkout gear is launched and use described left support bar 3 and right support bar 4 solidFixed;
In the time that described checkout gear does not use, described left support bar 3 and right support bar 4 are dismantled, and by described checkout gearDrive automatically and roll by clockwork spring.
In addition, the warp hardness in above-mentioned grid 5 is higher than parallel.
In concrete use procedure, first in sample prescription survey area, meadow to be detected, place above-mentioned detection device;
Then the detection method that embodiment provides according to the method described above operates, and obtains a certain species at grass to be detectedCover degree in sample prescription survey area, ground;
After detection, remove the support bar of checkout gear, checkout gear is regained.
