| Abstract: | 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). |
