METHOD OF MEASUREMENT perimeter and area of ​​leaves in trees

摘要

1. A method of measuring the perimeter and area of ​​the sheet of woody plants, comprising a substrate with a white surface laying on the measured bottom sheet and top sheet superposed on the transparent map mosaic for the measurements, the longitudinal axis of the sheet plant combined with a mosaic grid lines, then the sheet through mosaic with a transparent grid photographed after the picture is placed in the memory of a computer, and measurements of length and width of the sheet operate in cells of the grid in the zoomed image mosaic plant leaf, wherein Thu a further measured sheet perimeter with the scale mosaic cells by the number of cells through which the ridge line of the sheet edge, wherein the area of ​​the sheet is defined as the sum of the total cells within the sheet surface and incomplete cells along the perimeter of the sheet also taking into account the scale mosaic cells, and then leaves, located on one of the local crown area woody plant, calculate descriptive statistics and indicators on them estimate the required number of repeats of measured leaves on separate dates vegetation fox Tevi wood rasteniya.2. A method of measurement of perimeter and area of ​​the sheet of woody plant according to claim. 1, characterized in that prior to the measurement picture of the sheet in the computer memory undercut extra edge to the perimeter of the sheet, and then increase the convenience for cell counts to A4.3 format. Method perimeter measurements and leaf area in woody plants according to Claim. 1, characterized in that the length and width of the sheet is measured by the number centimeter cells with the addition of small cells with regard to their magnitude, e.g., 2 × 2 mm, and the ends of the photographic image of the sheet edges and of shares m
