摘　　要：以Richards生长函数为基本模型,根据安徽省贵池市各林场的29块意大利杨树无性系临时标准地和标准木调查材料,拟合出林分生长预测模型,对其生长量和生长率进行估测。并对胸径、树高、单株材积、蓄积量分别用拟合样木,检验样本以及拟合数据与检验数据合并组成的样本数据进行了拟合效果检验。According to Richards function,several models were imitated for estimating poplar growth and its rate yearly based on 29 plots of poplar temporary and fixed standard stands in Guichi Anhui.The predict effect of diameter in breast high,height,volume of timber were examined by the data of imitated sample and examined sample.
