摘　　要：本文利用'中国化学期刊文献引文数据库'对化学基础研究领域的38种期刊进行了引文聚类分析.聚类结果基本上反映了期刊之间的类团关系,综合性期刊在两阶段内的归类表现出不稳定性.对23种专业期刊再次进行聚类,结果表明,消除综合性期刊的干扰之后,聚类结果与实际情况吻合得更好.Using the Citation Database, established for 38 chinese core journals in the field of chemistry, the hierarchical clustering of these journals has been studied. The achieved results in great extent coincide with the ordinary classification of chemical journals in library practice. Clustering study has been carried out in two stages. During this course some changes have taken place in hierarchies of comprehensive journals of chemistry, i.e. on these journals can be find papers in almost all fields of chemistry, After clearing up the influence of the comprehensiveness of these journals on their practical hierarchies the results gained by hierarchical clustering method are better keeping with the actual situation of the classification of chemical journals in general.
