Problems solved by technology

[0022] Generally speaking, the instrument measurement method requires high equipment and is inconvenient to operate in the field, but it is powerless to measure the sub-coverage of herbaceous plots
[0023] At present, the domestic measurement of the coverage of herbaceous plots mainly uses visual estimation methods, probability calculation methods, and less application of instrument measurement methods; mainly qualitative research, less quantitative research
And there is less measurement of sub-coverage, and there is no special instrument to measure it

Abstract

The invention discloses a measuring apparatus of the coverage and partial coverage of a herbage sample area. The measuring apparatus includes a quadrat frame used for determining a herbage quadrat; and a punch block used to be mounted on the quadrat frame. In measurement, the coverage and partial coverage of the herbage sample area are calculated according to the record of plant species names at the needle fall point on the punch block. The measuring apparatus of the coverage and partial coverage of a herbage sample area is simple in manufacture, convenient in carrying, easy in operation, exact in measuring result and wide in application range and plays a positive auxiliary role in the research of biodiversity, especially the biodiversity of herbosa.

Description

Technical field [0001] The invention relates to an instrument for measuring the coverage of plants, in particular to a measuring instrument for the coverage and sub-coverage of herbaceous plots. Background technique [0002] Vegetation coverage refers to the percentage of the vertical projection area of ​​the canopy, branches and leaves of all vegetation including trees, shrubs, grasses and crops on the ground of the growth area in the area of ​​the study statistical area. Specifically, it is divided into total coverage-coverage of all communities ; Layer coverage-the total coverage of plants in each layer; sub-coverage-the coverage of each or each type (such as grasses, legumes, etc.) plants. It has the following two characteristics: [0003] (1) To calculate the vegetation coverage, the aboveground part of the vegetation must be vertically projected to the ground of the vegetation growth area. For example, when measuring vegetation coverage on a hillside, it is required to proj...
