Most importantly, the method can reduce resource waste and is beneficial to protecting ecological environment under the condition of ensuring the normal growth of trees. However, we cannot know the radial growth of the tree accurately. Therefore, in tree-annual ring study, we consider the annual ring as an approximate circle, and determine the radial growth (BAI, basal section growth increment) by the area of the ring. The collected sample core leaves a corresponding circular arc at the position of the medullary core. When the circular arc left on the sample core is known, and the BAI of the tree annual ring is calculated, the position of the circle center needs to be accurately estimated, and the corresponding radius is measured to obtain the area of the circular ring. In the past, drawing is mainly performed by using a ruler to determine the circle center and the measurement radius, and the method is time-consuming to operate and low in accuracy. In addition, in the existing working mode, a large amount of time is consumed in the process of determining the circle center and calculating the BAI, the BAI of 15 sample cores is completely calculated, more than 8 hours of working time is needed, time and labor are wasted, and the workload is large.
