In this study,natural secondary Abies nephrolepis forest of Wangqing County,Jilin Province is regard as research object using 172 subcompartment data,178 reset sample plot and 96 anatomical tree data.Based on the site classification results,the height of dominant Abies nephrolepis at the basal age,and the unit area stand growing stock,the site quality comprehensive evaluation system of the Abies nephrolepis secondary forest of Wangqing district is established.The stand unit area growing stock,the site quality is classified into three grades:good(I),medium(II) and poor(III).The site with good quality(I) has relatively high altitude,thick soil layer,gentle slope most of which are shade slopes,good forest form,complete structure and high comprehensive benefit.The medium (II) quality site is the key point of tending and management to keep the stability of the stand and to promote progressive succession.The poor (III) quality site has lower altitude,thinner soil layer,bigger slope most of which are sunny slopes,bad and complicated forest form for which differential measures can be taken based on the site evaluation results during the course of forest management.
