对古树树龄测定方法的若干思考

准确测定古树树龄是对古树进行科学保护的前提，也是古树保护研究的重点问题之一。对现有古树树龄测定方法及其应用案例进行了分析，指出文献法、访谈法、年轮鉴定法仍存在诸多不足和局限，而针刺法、14C测定法、CT扫描法，由于受取样及当前技术条件的限制，不能实现对古树树龄的准确测定。实践中，应根据被测古树的特点，选择多种测定方法，共同实现对古树树龄的准确测定。同时提出，数学模型法是未来古树树龄测定的优势方法，并对该方法的研究重点进行了探讨。

Some Thoughts on the Method of Measuring the Ages of Ancient Trees

Accurately measuring the ages of ancient trees is not only the premise of scientific protection of ancient trees, but also one of the key issues of ancient tree protection research. This paper analyzes the existing ancient tree age determination methods and their application cases, and points out that there are still many deficiencies and limitations in literature method, interview method and tree ring identification method. Although acupuncture method, carbon 14 method and CT scanning method are widely mentioned in some papers, it is not suitable for accurate age determination of ancient trees under current technical conditions. In practice, according to the characteristics of ancient trees tested, a variety of testing methods should be selected to realize the accurate measurement of the ages of ancient trees. At the same time, it is suggested that the mathematical model method is the dominant method for the age determination of ancient trees in the future, and the research emphases of this method is discussed.
