摘要
According to the data of analytic trees,an empirical equation of tree growth was constructed,with annual growth as variable and time and annual precipitation as independent variables. Through arithmetical operation including derivation of function and so on,the effect of precipitation on tree growth was studied through the rejection of effect of time factor.
