摘　　要：在查阅种质资源调查和母树林建设的基础上,通过对秦岭南坡的洛南、柞水、镇安县栓皮栎天然林分进行标准地调查试验对比,选出3处优良林分,然后在得分最高的1处优良林分利用优势木对比法选出栓皮栎优树10株。并根据基层工作参考有关资料进行秦岭南坡优良林分及优树选择研究,旨在推进秦岭南坡建立栓皮栎良种选育和母树林培育提供借鉴。该研究仅在秦岭南坡商洛市等县开展,在区域位置、环境气候方面具有一定的地理位置、环境气候局限性,但其优良林分和优树选择研究方法和研究结果可以为秦巴山区、陕西周边区域发展栓皮栎、推广优良品种、推进系列产品开发提质增加资源方面提供有益参考。Based on the investigation of germplasm resources and the construction of parent forest,three excellent Quercus variabilis stands in Luonan,Zhashui and Zhen’an counties on the south slope of the Qinling Mountains were selected through standard site investigation and comparison,and then 10 superior Quercus variabilis trees were selected from the top one by using the dominant tree comparison method.Based on the relevant information of grassroots work,the author conducted a study on the selection of fine stands and superior trees on the southern slope of the Qinling Mountains,aiming to provide reference for the establishment of fine variety breeding and parent forest breeding of Quercus variabilis on the southern slope of the Qinling Mountains.This research is only carried out in Shangluo City and other counties on the southern slope of the Qinling Mountains,which has certain geographical location and environmental climate limitations in terms of regional location and environmental climate.However,the research methods and results of the selection of excellent stands and superior trees provide a useful reference for the development of Quercus variabilis,the promotion of excellent varieties,and the promotion of the development and quality improvement of a series of products to increase resources in the Qinling Bashan Mountains and the surrounding areas of Shaanxi.
