摘　　要：目的:通过对应比较生态学中的食物链与叙词表相关关系链接成的特定概念链,将食物链的能量流动递减理论应用于相关关系的构建中,为叙词表编制工作提供新的思路。方法:假设概念链上概念间的相关性符合食物链能量流动逐级递减理论,以农业领域中一个主题概念为起点,逐级获取相关概念,并按照“概念链”的构造方法,将概念依次连接成概念链。在中国知网(CNKI)中获取各个概念2000-2021年的历年文献量,并用SPSS软件对数据进行统计分析。结果:经过统计分析,有73.3%的概念链符合假设。结论:概念间相关性递减的规律可以为叙词表的编制和维护工作提供参考。Objective To apply the diminishing energy flow theory of food chain to the construction of correlations by comparing the food chain in ecology with a specific chain of concepts composed of thesaurus correlations,and to provide new ideas for the thesaurus construction.Methods Assuming that the relevance between concepts in the concept chain is consistent with the theory of diminishing energy flow in food chains,taking a subject concept in the agricultural field as the starting point,the related concepts were acquired step by step,and the concepts were connected into a concept chain according to the construction method of“concept chain”.The data were obtained from CNKI for each concept from 2000 to 2021 and statistically analyzed by SPSS.Results After statistical analysis,73.3%of the concept chain met the hypothesis.Conclusion The law of decreasing relevance among concepts can provide a reference for the compilation and maintenance of thesaurus.
