Embodiment 1

[0024] figure 1 Shown is a schematic structural diagram of a laser measuring instrument for herbaceous vegetation coverage. like figure 1 A laser measuring instrument for herbaceous vegetation cover includes a main body beam 100 and a support vertical bar 200. The main body beam 100 and the support vertical bar 200 are fixed at the center of the two by a U-shaped 360-degree rotating clamp 300, and Through the U-shaped 360-degree rotating clamp 300, the support vertical bar 200 and the main body beam 100 are vertically and horizontally arranged or arranged at any angle. The main body beam 100 and the support vertical bar 200 are detachable. Wherein, the support beam faces the side of the ground to install a plurality of regularly arranged laser lights; the support vertical bar 200 includes a vertical bar main body 210 and an extension bar 220, and the vertical bar main body 210 and the extension bar 220 are fixed by screws 230, The lower end of the support vertical rod 200 is...

Abstract

The invention discloses a laser measuring instrument for coverage of grass land vegetations. The laser measuring instrument comprises a main body crossbeam and a support vertical rod, wherein a plurality of laser lamps are mounted on one side, facing towards the ground, of the main body crossbeam at equal intervals; and the support vertical rod and the main body crossbeam are fixed through a U-shaped 360-degree rotating clamp at the centers of the support vertical rod and the main body crossbeam and can be arranged in vertical and horizontal manners or at any included angle through the U-shaped 360-degree rotating clamp. By virtue of simple construction, the equidistant projection of laser to the ground is realized; by observing the number of light spots directly emitting plant bodies, the total coverage of the land vegetations can be calculated, and the species coverage (division coverage) of the plants can be also calculated. The laser measuring instrument has the beneficial effects that a testing method is simple, a calculation method is simple and convenient, and a single quadrat can be repeatedly measured by the rotating the main body crossbeam; the time and the labor are saved; the projections of laser beams are clear and can be identified by naked eyes, so that the subjective arbitrary is eliminated, and the measuring efficiency and accuracy are effectively improved; and the laser measuring instrument laser measuring instrument is simple in structure, easy to assemble and disassemble and convenient to carry.

Description

technical field [0001] The invention relates to an instrument for measuring vegetation coverage, in particular to an instrument for measuring herb sample land coverage. Background technique [0002] Vegetation coverage refers to the percentage of the ratio of the vertical projected area of ​​the aboveground part of the plant community or each individual to the quadrat area. It reflects the denseness of vegetation and the size of the photosynthetic area of ​​plants. Vegetation coverage (coverage) is one of the important tasks in ecological monitoring and desertification monitoring, and it is also an effective index for evaluating grasslands, pasture conditions, land degradation and desertification. The measurement of large-scale grassland vegetation coverage is of great significance to the production of agriculture, forestry and animal husbandry in arid and semi-arid ecologically fragile areas. [0003] The study of vegetation coverage is also of great significance for soil...
