摘要
通过对解析木材料的研究,得出树木生长的拟合经验方程,即以年生长为变量、以时间和年降水量为自变量的函数,通过对函数的求导等数学运算,得出通过时间要素影响的剔除,来研究降水对树木长的影响作用。
Through studying the data of analytic materials,the fitted empirical equation of growth of trees was obtained,taking the annual growth as variable and taking the time and annual precipitation as a independent variable,through mathematics operation(derivation of the function and so on)and the rejection of affecting factor of time,the effect of precipitation on growth of tree were studied.
