| 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。

| Abstract: | 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. |
