Abstract
The invention discloses a tree height measuring triangular rule and an application method thereof. The tree height measuring triangular rule comprises a measuring ruler and two measuring ropes, wherein the length of the measuring ruler is 30 cm, the zero graduation positions of the two measuring ropes connect the two ends of the measuring ruler respectively, and a 30 cm position and a 51.96 cm position are respectively marked on the measuring ropes. The technical scheme of the application method is as follows: by using two tree height measuring triangles formed by the measuring ruler and the two measuring ropes in the tree height measuring triangular rule, selecting two observation points and aiming the visual line along the measuring ropes at treetop and tree bottom respectively, and measuring the tree height through measuring the horizontal distance of the two observation points without measuring the horizontal distance from observation points to the tree. Thus the disadvantage of unable measurement of the horizontal distance from the observation points to the tree in an observation area is overcome. In the invention, the measuring tool is simple and the operation is convenient. Thus the workload is minimized and the work efficiency is raised.
Description
One, technical field
The present invention relates to measure in a kind of forest resource monitoring the method for the height of tree, particularly a kind of height measurement set square and using method thereof.
Two, technical background
In traditional forest resource monitoring, the measurement of the height of tree is an insoluble problem always, usually it is high to adopt height finder to survey, eye estimating method or cooperate with tape measure, scale by box compass, transit, use the triangulated height method and carry out the measurement of the height of tree, above the whole bag of tricks all exists its shortcoming:
1. in the forest zone, cooperate with tape measure, scale by box compass, transit, when application triangulated height method measures the height of tree, be subjected to the restriction of factors such as landform, the gradient, the density of crop, make horizontal range be difficult to measure, and calculate comparatively complexity, limited the use of instrument;
When 2. adopting height finder to measure the height of tree, need measure the horizontal range of measuring point, when having obstacle to be difficult for arriving between measuring point and the trees, limit the use of height finder to trees;
3. adopt eye estimating method, precision is lower.
So traditional height of tree measuring method is subject to the restriction of forest mesorelief complicated factor in the forest resource monitoring journey, make horizontal range be difficult to measure, limited the use of classic method, and workload is big, precision is not high, therefore, the quick measurement of the realization height of tree becomes this area scientific and technical personnel problem anxious to be solved.
Three, summary of the invention
In order to overcome a lot of troubles that existing height of tree measuring method is brought inevitably in the forest resource monitoring process, improve accuracy of observation and work efficiency, the purpose of this invention is to provide a kind of height measurement set square and using method thereof, be implemented in the rapid measuring that to measure measuring point height of tree to the condition of the horizontal range of trees, overcome the shortcoming that prior art exists.
The object of the present invention is achieved like this: form the height measurement set square by a survey chi and two lining ropes, wherein surveying chi length is 30CM, and two lining ropes zero delineation positions link to each other with survey chi two ends respectively, and delineating respectively on the lining rope has 30CM, 51.96CM position.
Survey chi in the height measurement set square and form two height measurement triangles with lining rope, the lining rope that wherein to survey chi and two length be 30CM is formed first height measurement triangle, and the angle of two lining ropes is 60 to spend; Survey chi and two second height measurement triangles of lining rope composition that length is 51.96CM, the angle of two lining ropes is 30 degree.
A kind of height measurement method that realizes the height measurement set square, at first, the hand-held chi upper end of surveying makes it sagging naturally, advance and retreat by the observer, select first observation station, make along the direction of visual lines of first height measurement triangle top lining rope and can aim at treetop, can aim at the tree end along the direction of visual lines of below lining rope; Then, on the horizontal direction of first observation station, select second observation station, make along the direction of visual lines of second height measurement triangle top lining rope and can aim at treetop, can aim at the tree end along the direction of visual lines of below lining rope; At last, measure the horizontal range S between first observation station and second observation station, by digital-to-analogue
The high H of observation ebon that asks.
This invention compared with prior art has the following advantages:
When 1. measuring the height of tree, without the flat distance of surveying instrument to the trunk center, having overcome in surveying the district has abrupt slope or gully can't measure the shortcoming of horizontal range;
2. survey instrument is simple, easy to operate, has reduced workload, has improved work efficiency.
Four, description of drawings
The present invention is further described below in conjunction with drawings and Examples.
The height measurement set square is measured height of tree synoptic diagram.
Five, embodiment:
Utilize the method for the height measurement set square measurement height of tree different, done significant improvement with existing method, specifically:
Form the height measurement set square by a survey chi and two lining ropes, wherein surveying chi length is 30CM, and two lining ropes zero delineation positions link to each other with survey chi two ends respectively, and delineating respectively on the lining rope has 30CM, 51.96CM position.Survey chi in the height measurement set square and form two height measurement triangles with lining rope, the lining rope that to survey chi and two length be 30CM is formed first height measurement triangle, and the angle α of two lining ropes 60 spends; Survey chi and two second height measurement triangles of lining rope composition that length is 51.96CM, the angle β of two lining ropes is 30 degree.Embodiment is as follows:
In the topographic condition of forest zone complexity, surveying in the district has abrupt slope or gully can't measure under the situation of horizontal range, as shown in the figure: at first, the hand-held chi upper end of surveying makes it sagging naturally, by observer's advance and retreat, select first observation station, on first observation station, make observer's sight line aim at treetop by the lining rope above first height measurement triangle of being made up of the height measurement set square, the lining rope by the below can aim at the tree end simultaneously; Then, on the horizontal direction of first observation station, select second observation station, on second observation station, make observer's sight line aim at treetop by the lining rope above second height measurement triangle being made up of the height measurement set square, the lining rope by the below can aim at the tree end simultaneously; At last, measure the horizontal range S between first observation station and second observation station, need not to measure the horizontal range of observation station, by digital-to-analogue to observation wood
The high H of observation ebon that asks is two horizontal range S between the observation station.
