Description
Technical field
The present invention relates to a kind of device of judging angular range, relate in particular to a kind of device of judging angular range between many strains forest.
Background technology
When Tree Distribution is judged in the field, the horizontal sextant angle that often needs the adjacent nearest many strains trees of judgement individual plant trees and its to constitute on every side, analyze these trees homogeneity of many strains nearest neighbor wood distribution on every side, and with every strain trees many strains nearest neighbor wood is minimal structure unit with it, analyze the Tree Distribution of whole standing forest.At this moment, the general horizontal sextant angle size that does not need to measure accurately between forest, but need to judge which angular range the horizontal sextant angle between forest is in, or, use statistical methods analyst Tree Distribution then greater than still being less than some standard angles.
This just needs fast, judges conveniently, accurately the residing scope of horizontal sextant angle between forest, and in the present determination methods, naked eyes are judged very inaccurate, the common instrument that takes measurement of an angle extremely is not easy to measure the level angle between forest, therefore measure to get up to take a lot of work, time-consuming, judge also inaccurate sometimes.
Summary of the invention
The purpose of this invention is to provide a kind of laser angle-deciding instrument of simple in structure, easy to use, accuracy of judgement, this laser angle-deciding instrument is particularly useful for judging the scope of corner dimension between open-air forest.

Embodiment
The preferable embodiment of laser angle-deciding instrument of the present invention as shown in Figure 1 and Figure 2, comprise housing 1, the inside of housing 1 is provided with laser beam emitting device 4, described laser beam emitting device 4 is provided with a plurality of luminous points, can be to outside emission of lasering beam, described a plurality of luminous point comprises a benchmark luminous point 3 and a plurality of angle luminous point, and the angle between described benchmark luminous point 3 and the angle luminous point institute emitted laser bundle 7 is 0~180 °, can be preferred angle such as 0,30,45,60,72,90 °.Also can be in the angular range of 60~120 ° or 60~90 °.
In the specific embodiment, above-mentioned angle luminous point has two, is respectively standard angle luminous point 5 and right angle luminous point 6, and wherein the angle between 5 emitted laser bundles of standard angle luminous point and 3 emitted laser bundles of benchmark luminous point is 72 °; Angle between 6 emitted laser bundles of right angle luminous point and 3 emitted laser bundles of benchmark luminous point is 90 °.
Described housing 1 is provided with compass 2.Described housing 1 also is connected with handle 8.
The range of above-mentioned laser beam is more than or equal to 50 meters.
Concrete using method to laser angle-deciding instrument of the present invention is explained in detail below:
As shown in Figure 3, in carrying out field study, when naked eyes are difficult to determine 72 ° of compare big or small of angle α and standard angle of reference tree and any two nearest neighbors wood formation, but this its magnitude relationship of laser angle-deciding instrument auxiliary judgment.
Concrete using method is: the investigator hands laser angle-deciding instrument, stand on reference near the tree, choice criteria angle luminous point 5 and benchmark luminous point 3, two luminous points institute emitted laser bundle is 72 ° of angles, one of them laser beam is beaten on nearest neighbor wood 1, judge the magnitude relationship of 72 ° of nearest neighbor wood 1 and nearest neighbor wood 2 and the angle that forms with reference to tree and standard angle by the position relation of judging another laser beam and nearest neighbor wood 2, in order to Distribution Pattern according to forest individuality in the judged result descriptive analysis standing forest.Less than 72 °, adjacent wooden 2-4,3-4 and the α 24 that constitutes with reference to tree and α 34 be also less than 72 ° as adjacent wooden 1-2 among Fig. 3 and the angle α 12 that constitutes with reference to tree, adjacent wooden 1-3 with reference to the α 13 of tree formation then greater than 72 °.
As shown in Figure 3, because trunk itself has rugosity, for avoiding judging by accident, the investigator may stand in reference to principle judgement α angle that utilizes angle of circumference to equate by the tree and 72 ° relation.
In carrying out field study, setting up square or during rectangle investigation sample ground, can be according to definite sample ground starting point, the laser beam that is 90 ° of angles of using laser angle-deciding device of the present invention to launch is determined the direction on adjacent both sides.
Concrete using method is: the hand-held or fixed laser angle-deciding instrument of investigator, stand on sample ground starting point, select right angle luminous point 6 and benchmark luminous point 3, two luminous points institute emitted laser bundle to be 90 ° of angles, utilize this two bundles laser beam to determine sample ground adjacent edge line position.
Can also utilize the compass 2 on the laser angle-deciding instrument housing 1, field investigation and sample judge the roughly direction of circuit in setting up.In conjunction with 90 ° a pair of laser beam that angle-deciding instrument sends, also can determine another investigation circuit perpendicular to this circuit.
