摘要
树木年轮的轮数和宽度是进行树轮气候学、树木生长规律及森林生产力测算研究的重要基础,是研究树轮相关科学中的重要数据,在测量树轮数据时偏差的大小将直接影响各项研究的准确性和精度.针对树轮检测定年过程中遭遇的各种问题,为了树木年轮判读过程中的准确性和年轮测定速度的提高,从而基于Java语言设计实现了简单的树木年轮分析系统.旨在借助计算机程序对树木年轮样品的树芯图像进行自动判读,来确定树木年轮轮数、轮宽等数据,以此达成通过简单操作便可以高效、快捷的获取树木年轮数据的目的.最终实现对树木年轮检测的自动化,为研究树轮学等需要树木年轮数据的学科提供支持,提高效率.
The number and width of tree rings are an important basis for tree climatology,tree growth law and forest productivity measurement research.It is an important data in the study of tree-ring science. The magnitude of deviation in the measurement of tree-ring data will directly affect the accuracy and precision of each study.In view of the various problems encountered in the tree wheel detection and dating process,in order to improve the accuracy of the tree ring and the speed of the annual ring measurement,a simple tree ring analysis system based on Java language design is realized.It is intended to automatically determine the tree core image of the tree ring sample by means of a computer program to determine the number of wheel rings and wheel width of the tree,so as to achieve the purpose of obtaining tree ring data efficiently and quickly through simple operation.Finally,the automation of tree ring detection is realized, and research is provided to support the disciplines that need tree ring data,such as tree-wheeling,and the efficiency is improved.
