Abstract

Data from 233 sample plots of Pinus thunbergii and Pinus densiflora plantation were collected at different site conditions in Shandong Province.Firstly,the feasibility was verified in establishment of a common site index table for Pinus thunbergii and Pinus densiflora.The guide curve equation was Richards equation for Pinus thunbergii and Pinus densiflora,and the coefficient of determination (R 2) was 0.958 0. Then,site index table was established by means of relative dominant height,in which the baseline age was 30a,the interval of site index class was 1m,and the site index ranged from 5m to 12m.The site index table was demonstrated to be of high accuracy through significance test and prediction accuracy test,and it was applicable for site quality evaluation for Pinus thunbergii and Pinus densiflora planation in Shandong Province.The site index varied from 7m to 9m for 59.4% of the total 233 sample plots,and these sample plots were grouped into medium site quality.

Key words： Shandong Province; Pinus thunbergii; Pinus densiflora; site index table; site quality evaluation
