| 摘 要： | 将长白山白河林业局劲松林场的５４块样地用聚类分析法划分成６个植被类群，再用ＰＣ－ＶＴＡＢ程序中经过改进的Ｂｒａｕｎ－Ｂｌａｎｑｕｅｔ学派的植被排表分析法进行综合，产生了鉴别概要表，为各个等级的植被类群筛选出诊断种。此外，还用鉴别种地样地记录进行主成分分析，以验证诊断种的有效性，结果表明，ＰＣ－ＶＴＡＢ中的植被排表分析法是筛选鉴别种的有效方法，而鉴别种以显著地提高植被分析和排序的质量。

| Abstract: | Based on cluster analysis, 54 sample plots surveyed in Jingsong Forestry Farm, ChangbaiMountian are classified into 6 vegetation groups. Then, by means of an modified Braun Blanquet vegetation tabular analysis presented in computer programs, PC-VTA13, a diagnostic summary table is obtained and diagnostic species are determined for each group. Inaddition,to evaluate the efficiency of diagnostic species, a principal component analysis(PCA) is conducted using the available diagnostic species. It is proved that vegetationtabular analysis in PC-VTAB is an efficient way to select diagnostic species, and diagnostic species can significantly imporve the classfication and ordination of plant communities. |
