摘　　要：利用浙江省开化林场杉木人工林36块标准地和144株解析木资料,比较分析5个树高生长模型后,选择Krof式生长函数H=aexp(-b/Ac)作为优势高生长模型。在分析优势高生长过程的基础上,确定基准年龄为20a,立地指数级距为2m。通过公式变形和推导,使用较简捷的方法编制了浙江省开化林场杉木人工林立地指数表。检验结果表明所编立地指数表精度符合要求。The data collected from 146 plots of China fir plantations and stem analysis of 246 China fir trees were used to construct height growth models.Krof function H=aexp（-b/Ac） was selected for dominant height growth model of China fir in Kaihua Forest Farm.By analyzing the characteristics of dominant height growth,the results were as follows：baseline age was 20 years and the interval of site index class was 2m.Through the formula deformation and deduction,site index table was constructed by using a simple method.The test results show that the site index table precision meets the requirement,and the table was more practical.
