基于词汇丰富性的汉语二语作文质量研究
Study on the Quality of Chinese Second Language Composition Based on Vocabulary Richness

本文通过分析HSK动态作文语料库的近15万字作文语料，以词汇丰富性为基点，从词汇复杂度、词汇密度、词汇多样性以及词汇等级四个角度出发，通过SPSS统计分析，发现词汇复杂度与作文质量呈现显著性相关，词汇密度与作文质量无显著性相关关系，词汇多样性则因其计算方式的不同而呈现出较为复杂的态势，词汇等级也对作文质量具有相当的影响。
In this paper, through the analysis of HSK dynamic composition corpus nearly 150000 words com-position corpus, based on vocabulary richness, from the vocabulary complexity, vocabulary density, vocabulary diversity and four levels, through the SPSS statistical analysis, it is found that there is a significant correlation between vocabulary complexity and composition quality, but no significant correlation between vocabulary density and composition quality. Vocabulary diversity shows a more complex trend due to its different calculation methods, and vocabulary level also has consid-erable influence on composition quality.
