摘　　要："词汇丰富性"反映言语产出中词汇运用的丰富程度,是词汇知识的一个重要层面,对语言习得及其它语言学科的研究具有重要意义。然而词汇丰富性需采用定量方式测量,设计难度较大,许多手段的信度和效度存在争议;而且复杂的计算和统计阻碍了大部分的研究者。本文详细介绍了词汇丰富性——主要是词汇多样性和词汇复杂性两方面——的研究历程,阐述了各种测量手段的理论依据、实施步骤、计算方式、优越之处以及存在缺陷,希望能促进研究者了解和探索相关的问题。＂Lexical richness＂, which reflects the degree of richness of lexical use in speech production, is a very important aspect in vocabulary knowledge and has significant meaning to the study of language acquisition and other linguistic subjects. However, designing the measures for lexical richness entails quantitative approach, hence is a problematic task, with certain disputes about the reliability and validity of quite a lot of methods ; in addition, compli- cated calculation and statistics obstruct the majority of researchers. This paper is intended to shed light on the re- search progression of lexical richness--mainly lexical diversity and lexical sophistication, elaborating on the theoreti- cal rationale, conducting procedures, means of calculation, strengths and existing flaws of various measures. It is an- ticipated that this paper may facilitate the understanding and probing of related issues.
