摘要: 以秦岭华山松群落为研究对象,采用典型取样和随机取样相结合的方法在秦岭林区取400 m2的样地36块。运用植被排表分析法和Ward最小距离聚类的方法将秦岭华山松进行了分类。结果表明,秦岭华山松群落可以分为5个群丛组7个群丛:华山松+美丽胡枝子+荩草群丛;华山松+美丽胡枝子+毛叶轴脉蕨群丛;华山松+蔷薇+崖棕群丛;华山松+短梗胡枝子+深绿蒿群丛;华山松+陕西绣线菊+香青群丛;华山松+陕西绣线菊+光蹄盖蕨群丛;华山松+蛇梅群丛。同时针对不同群丛的特点提出合理化的经营和管理措施。

Abstract: Based on the data collected from 36 plots of Pinus armandii communities in Qinling Mountains,and by using vegetation tabular and Ward minimum range cluster analyses,the P.armandii forests in Qinling Mountains could be divided into 5 association groups and 7 associations types:Ass. Pinus armandii+Lespedeza formosa+Arthraxon hispidus,Ass. Pinus armandii+Lespedeza formosa+Ctenitopsis devexa,Ass. Pinus armandii+Rosa multiflora+Carex siderosticta,Ass. Pinus armandii+Lespedeza cyrtobotrya+Artemisia atrovirens,Ass. Pinus armandii+Spiraea wilsonii+Anaphalis sinica,Ass. Pinus armandii+Spiraea wilsonii+Athyrium otophorum,and Ass. Pinus armandii+Duchesnea indica.Reasonable management advices were put forward according to the characteristic of different associations.
