| Abstract: | In this study,291 dominant trees data In various site conditions were used to construct site index table from 7 mathematical models.The results indicated that Richards curve equation had the best fit among the selected curves.The datum age was set to 40 years.Exponential distance was 1m.Site index table of Platycladus orientalis were developed by using the method of relative advantages of higher.Tested by fit significance and forecast accuracy,the results showed that the site index table had promising precision,and it could be used on plantations of Platycladus orientalis in Shandong Province |
