摘要
《中国学术期刊 (光盘版 )检索与评价数据规范》将摘要作为A ,B ,C等 3类论文的必备项。为考察林业科技期刊中论文摘要的情况和不同类别论文中各类摘要的分布情况 ,统计分析了 2 0 0 0年出版的 9种技术类林业科技期刊的摘要篇数和字数。结果表明 ,有 4种期刊的摘要具有率在 80 %以上 ,但也有的期刊只有 40 %～ 5 0 % ,甚至更低。A类论文中 ,各类摘要的篇数排序为报道性摘要 >报道 指示性摘要 >指示性摘要 ;B类论文为报道 指示性摘要 >指示性摘要 >报道性摘要 ;C类论文为指示性摘要 >报道 指示性摘要 >报道性摘要。报道性摘要、报道 指示性摘要和指示性摘要的平均字数分别为 1 90 2字、 1 1 7 5字和 77 7字 ;多重比较表明各类摘要的字数存在极显著差异。摘要字数与摘要类别有关 ,还与一次文献的信息量和研究对象的复杂程度等有关。就某篇论文而言 ,报道性摘要具有唯一性。表 3参
