Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The following will describe an embodiment of the present invention in further detail with reference to the accompanying drawings, and as shown in fig. 1, a schematic flow chart of a method for detecting grassland-like coverage provided by the embodiment of the present invention is shown, where the method includes:
step 11: dividing a grassland sample investigation area to be detected into a plurality of small squares with the same size;
the grassland sample investigation area to be detected is 1m multiplied by 1m grassland investigation square, and the divided small squares with the same size are 100 small squares with the size of 10cm multiplied by 10 cm.
Step 12: estimating the coverage of a species within each cell;
in this step, the coverage of the species within each cell is set to 0.5 or 1, and the number of cells with a coverage of 0.5 and 1 is counted in species, specifically:
if the ratio of the total area of the vertical projection of a certain species in a small square grid to the total area of the small square grid is more than 0.5, recording the coverage of the species in the small square grid as 1;
if the ratio is not greater than 0.5, marking the coverage of the species in the small square as 0.5;
the number of small squares with a coverage of 0.5 and 1 was counted for different species.
Step 13: and adding and summing the coverage of a certain species in each cell to obtain the coverage of the species in the grassland sample investigation area to be detected.
For example, as shown in fig. 2, which is a schematic diagram illustrating the evaluation of the grassy sample coverage according to the embodiment of the present invention, for species a in the diagram, it is first counted whether the ratio of the total area of the vertical projection of species a in each cell to the total area of the cell is greater than 0.5, and if so, the coverage of species a in the cell is marked as 1; if not, marking as 0.5;
then counting the number of small squares with the coverage of 0.5 and 1 aiming at the species A;
