Annual ring width measurement method and system

Abstract

The invention discloses an annual ring width measurement method and an annual ring width measurement system, and relates to the technical field of tree measurement. The method comprises the following steps: taking a tree disk as a base disk; obtaining an annual ring width of each annual ring on the reference disk except for the annual ring closest to the heart center; obtaining the total width of all the annual rings on the tree disk to be measured except for the annual ring closest to the heart center; calculating the annual ring width of each annual ring on the tree disk to be measured except for the annual ring closest to the heart center. Due to the steps, the conventional method for measuring the annual ring width is not applied, so that a lot of actual measurement work is reduced, and the measurement efficiency and the measurement accuracy are improved; furthermore, the annual ring widths of other disks are only needed to be measured once except that the annual ring width of each year on the reference disk is needed to be measured, so that the operation is simple; meanwhile, the annual ring closest to the heart center is measured independently, and is not regarded as a proportionality coefficient, so that the error of other annual ring widths is eliminated.

Description

technical field [0001] The invention relates to the technical field of tree measurement, in particular to a method and system for measuring the width of annual rings. Background technique [0002] In order to study the growth process and characteristics of the same tree species under different tree species or different site conditions, the method of "dissection" is often adopted to divide the tree into several segments, saw the disc, and then decompose its diameter at breast height, tree height, volume, shape and number. We call this method trunk analysis. [0003] Although the technology of tree trunk analysis has a history of hundreds of years, it seems to be very mature, but there is something unreasonable, that is, when measuring the annual ring width of each section of a tree, the annual annual ring width on each disc All must be measured directly. When there are a large number of disks to be measured, if the annual ring width of each disk must be measured separately, ...

Problems solved by technology

[0003] Although the technology of tree trunk analysis has a history of hundreds of years, it seems to be very mature, but there is something unreasonable, that is, when measuring the annual ring width of each section of a tree, the annual annual ring width on each disc It must be measured directly. When there are many discs to be measured, if the annual ring width of each disc is measured separately, the workload will be very large, time-consuming and labor-intensive, and accidental errors will easily occur.
