摘要
本文研究了柏木生长量与树龄的关系、生长率与树龄的关系,提出了用来描述这种关系的几个简单公式。这些简单公式能比较方便和比较精确地根据树龄测定出柏木的生长量和生长率。
This paper deals with the relation between the current annual increment and the age in terms of the diameter breast height on Chinese Weeping Cypress and also with the relation between the growth percentage and the age.Several simple formulae to describe the relationship were studied, which are more convenient and more accurate to obtain the current annual increment and the growth percentage from ages for Chinese Weeping Cypress (Cupressus funebris Endl).
