Abstract

The present invention provides a laser quadrat device with small measurement error. The pole is arranged on the universal platform, and the first light source and the second light source are installed on the pole; there is a distance L between the first light source and the second light source; The power supply is electrically connected to the first light source and the second light source respectively; any one of the first light source and the second light source is an edge laser light source, and the other is a dot matrix laser light source or an edge laser light source; The projection of the beam on the ground is the first projection, and the first projection is a rectangular structure; the projection of the second beam emitted by another dot matrix laser light source or the edge laser light source on the ground is the second projection, and the second projection is four points Or a rectangular structure; the second projection of the four points coincides with the four vertices of the first projection; or the second projection of the rectangular structure completely coincides with the first projection. The utility model has the advantages of simple structure, convenient operation, easy portability and small measurement error.

Description

technical field [0001] The invention relates to a measurement device for quadrat investigation on grassland, in particular to a laser quadrat device. Background technique [0002] In the survey of ecological status, it is necessary to delineate the range of grassland on the surface. There are two existing methods: the first method is to measure the grassland manually. The manual measurement method requires a lot of auxiliary tools, which are inconvenient to carry and easily cause trampling damage to the grass under investigation. In order to avoid damage to the surveyed grassland, the second method is also included, which is to sample the grassland through the sampling device. The sampling device usually includes a laser transmitter and a bracket, and the laser transmitter is installed on the bracket. The bracket is usually a tripod, and the height and angle of the laser emitter can be adjusted. The adjustment of the angle and height is mainly realized by the universal pla...
